Montana has become the first state to prove 3D printing as an alternative to traditional concrete block structures. This is a big step because even though 3D-printed houses have been around for a while, they've kind of been looked upon with a certain amount of reticence because people don't really know what they're able to do. That makes sense because 3D-printed houses have only been around for a few years. They haven't really been able to be time tested the same way really old building methods have been like bricks and wood, which have been around for hundreds of years so we know how they last and how they hold up as a structure. This new regulatory approval from Montana now proves out 3D printing is a legitimate alternative to traditional manufacturing.
The machine that has been approved and the process that has been approved was created by Apis Cor you may have heard of them they're the ones who have created the largest 3D printed building in the world over in Dubai. The gentleman who actually pushed for this approval up in Montana wanted to use Apis Cor to produce a small development inside of Billions, Montana his name is Tim Stark. He is hoping that the new process will reduce the cost to build houses by about 30 percent both from the reduction of labor and the simplification of the processes and the material. He also hopes that it will reduce the time to produce new developments quite substantially as well which has been really important in the current kind of housing crisis that has existed. This is a big step for them regulatorily but it also proves that their materials and their processes have finally reached a point where they can be considered reliable.
3D-printed houses have always had the same sort of material challenges as other types of 3D printing. They are not able to run standard concrete through their nozzles as they're laying down these layers for a wall. The companies that have created these machines have had to create custom machinery and custom cement mix that are stable enough dry quickly enough and flow well enough to be able to be put down in layers and not have the whole thing melt as it's going up, which traditional concrete would do.
This is a great step forward it has proven out the technology and it has proven out that these are now ready to kind of be deployed. It'll still be a long time before 3D printed houses are really really commonplace but it is a good step. Let us know down in the comments about other things that you'd like to hear about and let us know about what you would use a 3D printed house for!
Have a great day everybody!
Here at Slant 3D, we end up producing a lot of products with PLA. We have gotten very familiar with the pros and cons of that material. We want to showcase things to be aware within the production of what can be done and what can't be done what increases cost and what decreases the cost.
PLA is one of the most common materials that we actually work with at Slant 3D. The reason for that is that many of our clients are already prototyping their products with their own 3D printers. This normally means they're very often led towards PLA because it's a very simple material to work with
at home or prototyping machines. However, PLA has a few advantages and disadvantages, especially when moving it into production that we're going to try to discuss here as much as possible.
First of all, PLA is bioplastic. There are several different grades of it it goes from a number called 4043 which is very brittle and is generally the low-cost option of PLA up to a number called 870 which is a very durable kind of less brittle more reliable almost abs replacement type plastic but it is more expensive so it is less scalable. This generally means PLA is used because of how brittle it is to be cost-effective. It's used for promotional products certain types of toys, good quality surface finish consumer products, that kind of thing, but it is almost never used for engineering products or high-reliability products. It's kind of a not tchotchke material but a consumer product brick block kind of material. that being said depending on the design it can be turned into anything, PLA does have a reasonable amount of flexibility so you can use designs like grip fins and that kind of thing within it that have just a little bit of flex to allow something to fit.
The tolerances of PLA since it's FDM there is generally fairly low pro tolerances of about 0.2 millimeters. That is the general tolerance to play with any sort of 3D printed part but if you were able to design in a wider tolerance that decreases the cost of parts long term because QC standards are lower and it's easier to produce lots of parts without having to check and have secondary processes to inspect them.
PLA has the largest color variation of almost any material the only other alternative might be like Pet-G and ABS but in PLA we were able to do custom Pantone matches for almost any color that you can imagine though those take a couple of extra weeks for creation.
PLA also is able to offer a fairly quick turnaround because it does not have as much setup cost it is quicker to start up it's quicker to set up. it's also very good for print on demand because it can produce one part out of the blue very reliable because it's a very stable material.
PLA is the lowest cost material in our catalog depending on the design but it lends itself to being highly automated with auto ejection and it is just a low-cost source of material that may be changing in the future so check back with future updates to see if other materials have become less expensive but in general that's a good rule of thumb.
Another thing to watch out for with PLA is its strength lower inner layer adhesion is not amazing compared to other materials it is more brittle so you do not want vertical surfaces that have layer lines going through them pointing straight up in the air because they will snap off with a reasonably small amount of force so those either need to be very reinforced or just try to avoid them if possible. the closer you can get to a sphere or a block is something that you want to do
PLA into scale generally kind of bottoms out fairly high certain other materials like pet g is actually cheaper at mass production if the part is right because the cost of raw materials is less even though PLA is easier to work with so there's a trade-off there depending on the design of the part Itself.
PLA has a very good surface finish, in general, it's very consistent because it flows smoothly and does not require any sort of complexity and setup or settings and it's also the most robust for adjusting to different types of geometries just again because it's a very robust material inside of the 3D printing process
PLA a fairly good general option for products with some sort of aesthetic leading component lamps, consumer products, household items, and certain types of toys PLA is not able to stand up to the outdoors it melts inside of a hot car it will literally deform and soften so it is not something for functional parts inside of a hot car in Arizona but it can be used within a house within a controlled environment
Hopefully that covers kind of the pitfalls in the general outline of PLA and where it can be used if you have any other questions comment down below and we'll try to create a video to cover some more of that stuff and let us know if there's anything else that you'd like us to talk about having a great day, everybody.
Bring the Rain with this durable and team-oriented squirt gun that makes water sports an actual battle.
Squirt guns have always lacked the team-based nature that make paintball and air-soft so much fun. Thus the idea of Splash Blaster was born. When having a water gun fight, it's always hard to have a team battle and be able to tell which team did the most damage. Splash Blasters eliminate this problem with Red/Blue Team Colors for your guns and ammo! With push action technology and an easy-to-grip knob, all ages can get in on the fun. Rugged and Simple, Splash Blasters are ready to let any age "Bring the Rain"
Made For Team Play
Traditional squirt guns are just made for free-for-alls, but what's the fun in rolling solo? That's why we created a squirt gun that is made for team play. Splash Blasters come in Red & Blue Team Colors so you can always tell the difference between friend and foe.
But we didn't just stop there, Splash Blasters also come with red and blue dye packets that you can add to your teams water supply. Wear all white and paint the other competitors with your color! This dye is washable and non-toxic, designed to color swimming pools and water features. But please don't spray the walls of a white house. Go to the park or something.
Multiple Firing Options
A good battle strategy always come with leaving your opponents guessing. Splash Blasters give you multiple firing options so you can be effective from any range. Storm the frontlines and engage in close-quarter combat with burst fire. Or sit back and snipe your enemies from up to 30 feet with one long stream. Coordinate a battle plan with your team to deal damage from all distances!
We got tired of shaking squirt guns to know how much ammo was left. So we wanted to make sure Splash Blasters actually showed how much was left in a wildly clear way. The barrel of the Splash Blaster is not only 360 transparent but also has milliliter markings to show how much longer until you need to reload.
In a pinch? Sometimes there just isn't enough time to pull water through the nozzle. With Splash Blasters, you can just remove the plunger, scoop your ammo, and get back in the fight!
Join The Battle
Splash Blasters bring a team-based aspect that other squirt guns can't compete with. Say goodbye to the days of free-for-all battles that leave you wondering who reigned supreme.
So, are you ready to take your water gun fights to the next level? Choose Your Side and Leave Your Mark, only with Splash Blasters.
