Generally when designing a piece of industrial hardware or a product prototype designers have to create all the models from scratch. But there are online resources full of functional 3D models that are explicitly designed for functional use. There are also resources for custom on-demand 3D Printed parts.
McMaster supplies 3D Models for many of their hardware products. These models are provided in the .STEP format so they can me edited and integrated large CAD assemblies, or printed to use in prototyping.
Part Mason is a partner company to Slant 3D. It is a repository of 3D printable models that can be created and used in as final parts in applications. Parts can be downloaded in a number of formats from 3D Printable .STL's to editable .STEP. They can also be ordered printed at any volume, whether it be 10 or 1000. Part Mason is basically a fully digital on-demand parts store.
Finding the 3D models is a challenge by itself. But then you need a 3D Printer that can reliably print those parts. Check out the Mason 3D Printer as a resource for 3D printing functional industrial parts.
3D Printing is truly starting to scale up. It is often a comparable process to injection molding both in volume of parts it can produce and the cost of producing those parts. Currently, based on Data from projects done at Slant 3D, 3D printing is on average less expensive than injection molding up 50,000 parts and we are working to push it to 100,000. But that is an average. What are the factors that make 3D printing more or less expensive than injection molding?
If you make more parts they cost less per part. This is true for injection molding and for production FDM 3D Printing at large volumes.
Many people have seen the graph below. The graph that shows that 3D printing costs remain constant regardless of volume. Nothing is more incorrect, those graphs are created by services with just a few machines.
Large scale 3D printing scales much the same as injection molding. The larger the job the better economics on materials.
Below is a chart of a part that could be produced with Injection Molding or 3D printing. The part requires 40g of material. The Mold would cost $10,000 upfront. The vertical axxis is on the logarithmic scale.
As you can see 3D printing follows a very similar curve to injection molding. And is in fact about 20% less expense up to 20000 parts and breaks even at about 45000 parts.
Warehousing and Inventory
While the graph above shows a situation where 3D printing and injection-molding eventually even out and have a mild price difference there is still the a cost that is not accounted for. Warehousing and lost inventory.
It is estimated that 15-25% of inventory is scrapped each year because it is not sold. There are also the warehousing costs of that inventory which can add another 5-15% to the cost of a product.
Even though 3D printing is higher cost than injection molding at very large quantities, its just in time capabilities ensure that almost no inventory is lost and very little of it every spends time in warehouses. Additive manufacturing allows a part to exist only in cyberspace until it is needed.
Design to minimize surface area, not the volume. This the general rule for FDM additive manufacturing. Volume is not really relevant to the cost of the parts. Surface area is. Surface area requires the most printing time and the most material. Internal volumes we are able to filling with internal lattices that maintain strength but do not add much material to the print.
The clearest depiction of this is with a simple cubic shape. With injection molding it would likely need to be design with ribs of some kind. But printing that design is expensive because it requires that the whole part be solid infill plastic. Which uses a lot of plastic increasing the print time and cost of the part.
If the part is to be optimially designed for affordable additive manufacturing it should be designed solid. We will then use our various softwares to design an internal lattice that matches the strength of the injection molded ribbed part. But since the walls can be thinner it will often use less material is an more efficient to print. Saving cost
LittleBots is an excellent example of good design for additive manufacturing. Each part is simplified and monolithic. Allowing internal lattices to provide strength and light-weighting. For this reason they will never have to transfer to molds because the cost of 3D printing is always equivalent on a per part basis.
There are about 20 large design conisderations that can affect price of 3D printed parts. Including overall complexity, need for support, part size. But minimizing material and print time are the largest the best way to do that is to minimize surface area.
Now let us invalidate all this with a giant "it depends." The cost of a part, with either process, depends on the size, design, tolerances, and materials of that part. Some pieces will never be economical with 3D Printing. Some pieces will be impossible with injection molding.
But there is an easy way to find out. Get a quote. We have qualified sales engineers who are ready to help you with the design and the quoting process to make sure that you are getting your product made correctly.
Many startups and small businesses are using 3D printer farms to test and scale products. The problem is that they don't have the experience to scale production to really large volumes.
Trainlab, Slate Robotics, Ohmnilabs, and others are all startups and small businesses that are using 3D printing to produce their final products. All of them have been faced with the choice of whether to bring production in-house or outsource it to services such as Slant 3D, Carbon, or Voodoo Manufacturing. But what are the benefits or dangers of both methods of mass producing 3D printed parts.
In-House 3D Printing
Many startups attempt to build a 3D printing pipeline in house. While this allows them to have more vertical integration, it is a process that has very high risk and high-long term cost.
Answer this question. If you are making an injection molded part why don't you buy an injection molding Press. Because it is expensive? Because you don't have the experience to operate it? Exactly. So why does 3D printing seem easier.
Desktop 3D printing has created the myth that anyone can use the process to make parts. But creating a few good pieces to test is very different from producing thousands of production quality parts consistently. Supply-chain, servicing, and part optimization all become factors. This requires that the startup essentially dedicate personnel to managing printers, and recreating the infrastructure that already exists in companies dedicated to production 3D printing.
There is also the problem of the machines themselves. A startup becomes dependent upon the company that manufactures the machines that they use. If that company should go out of business (which 3D printing companies have been very prone to doing) or just abandon support of the machine that the startup uses, then they are left up the creek without a paddle. Or with dozens of 3D printers that will have to be replaced.
Building a 3D Printing farm in-house does have the advantage of slightly faster turn-around, a bit more control. It also can decrease startup financial costs. But operationally it is expensive and risky because printer farms require skill, maintenance, and personnel to operate. These farms are also very inefficient because the startup has to create operational processes from scratch and source at low volumes.
Production 3D Printing Service
Services solve the problems of in-house 3D printing. Companies like Slant 3D, are able to dedicate all of their time, resources, and personnel to creating high quality plastic parts at scale. A scale that often makes the 3D printed parts more affordable than in-house versions with high overhead.
Slant 3D, itself manufactures its own machines. Ensuring that the factory is always supported and ready to produce. So if you make a part with us this year. You will be able to make the same part 5 years from now. It also ensures that Slant 3D is able to scale rapidly to implement new demand from clients as they grow.
Services are also able to take advantage of scale. Through strategic partnerships, and in-house filament production, the material costs of parts are less than if a startup were to source materials for their small projects.
The last advantage of services are the processes. 3D Printing is all these companies do. They are not creating a product and creating a smaller company inside the company to create that product. Since services are so focused they can implement the best in the industry hardware and automation, and ensure it is all operating at peak capacity.
This is what Slant 3D does. We produce 3D printed parts at scale so that companies don't have to. The same way injection molding services produce injection molded parts so that companies don't have to.
High Volume, Production 3D Printing is able to produce thousands of parts per week, eliminating warehousing and providing more flexibility in the design and production of parts. But there are several misconceptions and great abilities that people overlook.
3D Printing is often considered a slow process for making parts. 1 part at a time that is true. That is why we deploy hundreds of 3D printers, in our printing farm, all working in parallel so that even though a single part might take an hour to print, we are still producing hundreds of parts per hour.
Capacity constraints can sometimes slow down production of orders, just as with any process. But we are constantly building out more capacity so that is mitigated as much as possible.
FDM 3D printing has a decided advantage over all other 3D printing processes. We are able to to create any pantone required by the client in our plastics. Other processes are generally limited to black, gray, or white. If you want a specific color it is exorbitantly expensive. FDM printing allows us to create a part in any color of the rainbow, and everything in between.
FDM is one of the most versatile 3D printing processes created. If a material can be put into a thermoplastic filament then it can be printed with our machines. For this reason we are able to manufacture parts with materials ranging from simple Bio-plastics and ABS up to Carbon Fiber Nylons. We have even started work with metal printing which will allow us to print parts and then sinter them to create complex metal parts.
Out own material production capabilities also allow us to continue to experiment and develop new materials and mixes. So if you need a plastic we can make that plastic
3D Printed parts are often considered to be weaker than injection molded or machined parts. It is true that the properties of a part vary based on the direction of loading, based on the orientation during printing. This property is refereed to as anisotropic.
But this issue is vastly over-stated and often just wrong. The reason it is so prevalent is that designers have been attempting to apply traditional design principles to the 3D printing process. That is the equivalent of trying to make an aluminum plane the way you would make a wooden one. Similar end goal, very different details.
If an additive part is appropriately designed for the process then it can meet or exceed the performance of traditionally manufactured parts. And we have a team of engineers who are standing by to help you optimize your designs for the process.
Slant 3D has also developed new methods of 3D printing parts which reduces the anisotropic nature of the pieces. In many cases we can achieve 90-95% the strength of an injection molded part the part in the Z direction using additive processes.
This is another common misconception. The idea that 3D printing is 5-10x more expensive than other methods at scale.
Large scale 3D printing is generally less expensive than injection molding up to 20-50000 units just on the savings of tooling. Long term, the on demand nature of additive can make production cheaper than other large volume processes because warehousing costs are reduced which can constitute 10-25% of the cost of a part over its production lifetime.
Then there is the traditional understanding that 3D printing is cheaper than molding at low volumes just because of the savings in tooling. In this situation 3D printing can be 5-10x less expensive than molding.
Hopefully we have cleared up an fogginess about the capabilities of 3D printing and the parts that is creates. Is it a perfect process for everything? No. No process is. But it does offer a lot of advantages in cost and supply flexibility.

High volume Additive manufacturing offers an affordable option for creating industrial components like gears and rollers.
Over the lifetime of Slant 3D, we have had many opportunities to manufacture amazing products for clients. These have ranged from robotics components to Amazon Echo Covers. But there are a group of products that we have a special love for, Wheels and Gears. These fundamental parts are used in every aspect of engineering. They the transistors of the Mechanical world. But they are very expensive to manufacture.
The engineering time alone in the creation of good gears and rollers can be a large portion of the budget. But it has to occur in order to create a component that will work for your particular application. Just last year Slant 3D manufactured rollers for machinery handling pears. Pear Rollers are not an off the shelf component. So the engineering had to be done to create a roller with the correct profile. But once that was done 3D printing was a very viable method to produce several hundred rollers affordably and reliably. The alternative was to machine the parts which would have been exceptionally expensive for such a large part or to mold them which also would have been exceptionally expensive. Neither process allows any iteration either.
Whereas 3D printing was quick and affordable. And it allows the client to change the design 10 units in without substantial added expense.
Gears for agricultural equipment are also a common need. Large, bulky, sturdy gears for farm equipment are expensive to machine from a block of delrin. And they are nearly impossible to mold in some cases. 3D Printing allows for the creation of strong gears that can take the abuse of the farm.
And again, since 3D printing is so material efficient these large gears can be created for the same or less cost than off-the-shelf parts that will not fit the application.
Slant 3D is working on several initiatives to make wheels and gear more accessible and affordable via additive manufacturing. Stay tuned for those in the future.
But if you need your rollers, wheels, or gears manufactured today get a quote from Slant 3D and compare production 3D printing to all the other processes available.
What is the Process of preparing a product to be manufactured with high volume production 3D printing?
Production 3D Printing is able to produce 100,000's of parts more affordably than injection molding. This savings is a result of the eliminated upfront cost of tooling and reducing design time and the long terms costs of warehousing.
But what is the process of moving a product into Production 3D Printing? It is very important to know this process to ensure that there are as few delays as possible as you are going into production.

The Most Important Thing
The most important thing is to make sure that you part is designed and optimized for production 3D printing. This makes sure that the quality, performance, and cost of the part is the best case possible. Additive manufacturing is rarely an exact replacement to injection molding. It is an alternative process that must be considered during design. That is why we keep a team of engineers who are the world leaders in design for additive manufacturing and they are here to make sure that your part meets your needs.
3D Printing is increasingly being used by businesses. And it is not just being used for prototyping. The ability to iterate on products and create complex geometries are both enticing to create parts at production scales. And with technologies such as our Production 3D printing Farm, large scales are feasible. But during the design and prototyping stage sampling, verfication, and design can increase up-front costs to create a 3D printed product. That is why we created the Mason 3D printer for businesses
The Mason is a 3D printer derived from the production 3D printers used in our large scale 3D printing farm. Because of that, any part made on the Mason will be identical to the parts coming out of the Slant 3D Printing Factory. This means sampling is no longer necessary. Clients only need to make a prototype on the Mason that is up to Spec, and then thousands more can immediately be produced with identical settings and characteristics on the Slant 3D farm. Prototype to production with no steps in between.
There only leaves the problem of getting those settings right on your prototype. Design for production 3D printing is an entire discipline, and very few truly understand how to optimize a part for large volumes. And while the machines may be identical from prototype to production, materials could vary if the client is using a spool of filament off of Amazon.
So to standardize the workflow completely. We created OnSite. Onsite is program that connects a Mason 3D printer directly into Slant 3D. An Onsite Subscription provides stardaized materials and access to profession file preparations and optimization. So every variable is eliminated in the prototype stage. Mason+Onsite gives you completely final production-ready prototypes. Not to mention machine insurance, discounted setup, zero sampling costs, and low cost high quality filament.
With the Mason 3D printer combined with an Onsite subscription we have made is possible for businesses to create, and quickly scale 3D printed products as easily as a software company might make an app.
Sculpteo's annual "State of 3D Printing" for 2019 shows how enterprises are increasingly using 3D printing and additive manufacturing for end-use products.
These and many other fascinating insights are from Sculpteo’s 5th edition of their popular study, The State of 3D Printing (29 pp., PDF, opt-in). The study’s methodology is based on interviews with 1,300 respondents coming from Europe (64%), United States (16.6 %) and Asia (20.2%), which is the fastest growing region internationally today as measured by this survey over five years. Eight industries are included in the research design including Industrial Goods (13.6%), High Tech (10.6%), Services (9.9%), Consumer Goods (8.6%), Health & Medical (6.2%), Automotive (5.7%), Aerospace & Defense (5.5%), and Education (4.9%). For additional details on the methodology, please see pages 6 and 7 of the study. Key takeaways from the survey include the following:
3D Printing has creating an incredible opportunity for designers to bring physical products to life. Websites such as Amazon, and Etsy, and businesses of all sizes have seen an influx of true 3D products that are as good, if not better than, traditional manufacturing processes.
But there has been a problem. Most of these products are made by very small concerns and have little ability to scale. This is because the cost to create and scale a 3D printer farm that can meet large scale demand is as great, or greater, than the cost to build traditional tooling.
At Slant 3D we have been working to eliminate the barriers to bringing physical products to market. We started by building one of the largest and highest volume producing factories of 3D printed parts in the world. With this next step, we are making it easier to access and utilize that 3D printing factory.
Here is the Mason and the Onsite Program, a pipeline from prototype to production of 3D printed parts
The Mason 3D Printer
Many clients that come to Slant 3D have a product that they have been printing with traditional FDM Machines. But since they are using some consumer machine the parts they make might not be the same as the pieces produced by Slant 3D. So a few cycles of sampling and verification have to occur. Which can slow down a product launch and add expense. If they had access to a printer that gave the same results as those used in our 3D printing factory then it would eliminate that setup process.
At Slant 3D we have spent several years developing new 3D Printer technology. Working to create industrial machines that are able to be deployed by the thousands to produce 100,000's of parts for clients as an alternative to injection molding. We have become very good at making 3D Printers.
The Mason 3D printer is a prosumer machine derived from our industrial printers. With it, users are able to make prototypes at their business with a workhorse machine, and when they are ready to scale up production of those parts all they have to do is send the final design and print settings to Slant 3D and they will translate directly into the production process. Eliminating sampling, and redesigns. The Mason now makes it as easy to create a product and scale it as making an app.
When you create an app you test it on your phone. If it works there it works on most similar phones. Now, when you create a product you can build it on the Mason. If it turns out right there then it can be produced by the Thousands immediately by Slant 3D.
The Mason is now available for preorders now for $750. Shipments will begin in early June of 2019. To get more details on the specs of the Mason visit its main Page.
The 3D Printing industry suffers from a huge lack of reliability. Colors and quality of filament change. Machines and the companies that make them disappear and go out of date. We want to eliminate all of those problems.
With Onsite we provide insurance for your Mason 3D Printer. If it breaks down then we will replace it within 2 days to ensure that you are never held up in your work. We also provide a 20% discount on all of our premium filament. This is the same filament that Slant 3D uses in production. So any part made with that filament on the Mason 3D printer will be identical to the parts produced by Slant 3D. Creating a perfect pipeline from prototype to production of 3D printed products.
And if you are a business or Designer that has a high demand for 3D printing, the Onsite program with discounted filament will easily pay for the printer in under a year. And you have the added value of the manufacturing backend of the Slant 3D Factory.
Another problem that many businesses run into is simply the operation of 3D printers. Preparing a CAD file for printing is a skill unto itself. With the Onsite Business Subscription companies immediately gain access to 3D printing expertise.
To implement Onsite Business the Mason 3D printer of the business will be upgraded with cloud connectivity. Then whenever a Design needs to be printed it will be uploaded to Slant 3D and one of our experts will slice it and print it at the client's desired machine. It is like having 3D printer experts in house.

We are very excited about the Mason and Onsite. The are going to fundamentally change the product development process. It will no longer be a set of disjointed suppliers and experts. We have created a clear and easy path to go from prototype to production without interruption. It is now possible to create a physical product and scale it as easily as it is to create a scale digital product.
Production 3D Printing offers a low-cost-of-entry and flexible alternative to injection molding when creating new toys. Allowing designers and businesses to more readily break into the global toy market and scale up.
Toys are one of the largest markets for final plastic products in the world. Valued at nearly 89 Billion dollars per year, toys are also lucrative. The trouble is that toys are risky and subject to little more than the whim of the consumer. Literally one weeks consumers will be buying the latest fidget spinner, and then the next week stocking up on branded Avengers Endgame action figures.
The toy industry is dominated by the Likes of Lego, Hasbro, and Mattel. Organizations that can afford the cost of design, tooling, and marketing of literally hundreds of SKU's of toys from 1 month to the next. With 10's of thousands of dollars for each variations, the cost to create a toy is very high. And when the toy is made there is really no guaratee of its success. They are subject to the 50-70% failure rate of any business.
So how does a small company, startup, or lone inventor break into the toy industry, when the the cost of entry and risk is so high?
The problem is in the tooling. That high upfront cost to get started. And the high cost to change if a product is not successful. Molding and traditional tooling are what makes the cost-risk relationship so bad. But there is a process that does not have that high initial tooling fee but will allow you to grow should your toy take off. Additive Manufacturing or Production 3D printing.
Additive manufacturing is when a part is literally grown from a feed of plastic. Traditional manufacturing carves of stamps a shape. 3D printing just makes it appear. Additive is also a digital process. Meaning that, to use it, all you need is a 3D model of your product and it can be created.
Another benefit of the Digital nature of 3D printing is that if a product needs to be changed, updated, or completely replaced, all it takes is an e-mail with the updated 3D design. With no new tooling or molding costs a physical part can be tweaked while it is being made.
Production 3D printing has also reached a scale where if you gain success and are selling thousands, 10's of thousands or more, it can keep up and maintain pricing comparable to injection molding. If a part costs $0.25 for 10,000 units with injection molding after the mold costs, it is likely that production additive can have a similar cost profile without the molding costs.
Additive manufacturing also eliminates the need to create 10,000 pieces. This might be more expensive per part that making large quantities, but it allows a business to experiment and test a market, and not be stuck with the high cost of having to ship and store thousands of pieces. Companies like Slant 3D also often have fulfillment systems, so you create a product and upload it to our system and then when a customer makes an order, the part is printed and shipped right from one of our facilities. (You can learn more about 3D printed product fulfillment here.)
Toys are a risky business. But they can be very lucrative when they are successful. But startups and inventors need a resource that allows them to experiment with production quantities and scale easily without high up-front costs. Traditional manufacturing does not meet those needs. Production Additive manufacturing does allow for this. It lets toy designers make 10 toys and test them, make 1000 toys and sell them, and then make 100,000 and get rich. Just imagine what you could create if the cost to make a toy was not so high
Slant 3D is one of the leaders in high-quantity additive manufacturing. We work continuously with small business and corporate clients to bring new products to market affordably using our production 3D printing farm. Learn more about our capabilities here.
