Details
How Long Does is Take for a Product to be Printed? Slant 3D works to produce any 3D printed part within 1-3 business days. So if your customer orders a custom cookie cutter on Tuesday, it will be shipped out to them no later than Friday. Cost? Since Slant 3D operates at such a large scale so smaller new products and stores can take advantage of of our economies and automation. That makes our cost of production very low. There is a monthly membership fee of $50 and then the quoted cost to produce your product. We understand the challenge to start a new store. But there are no minimum quantities, and you only pay for parts when a customer buys from them. What is the Quality? All of the Etsy stores that we have worked with have only 5 star reviews. BakersStreetCutters is a great example. We do not let quality drop. And if an order is not up to spec? We will reprint, reship, and refund the order immediately. Can I do more than 1 Item? You can do infinite items. We work with stores that do customization of every single item. So a doorstop may have a name engraved. And we work with stores that have 5-20 core products that we manufacture or support them with. There are no restrictions on the number of designs that we can produce for you. What 3D Printing Process do you use? We use the FDM 3D printing. This is most commonly used on Etsy and is the lowest cost 3D printing process in existence. And it allows our clients to access low cost hardware for prototyping of new designs.
Etsy is a great platform that has great opportunity for 3D printed products. And now it is easier than ever to start a small online business with 3D printed designs.

Is the shipping cost part of the quote? I only got one dollar amount and I am not sure if that includes the shipping, or if that is added extra for the customer?
