INFO & FAQ

Why Are Prices So Cheap?

We are able to drop our prices so low because the majority of our components are lightly used or refurbished. We also charge little to no extra cost on 3d printed goods, so you pay the real price, not a gross estimate.

What Is the Difference Between the 3D Printer Materials?

PETG, TPU, PLA, and ABS are all popular 3D printing materials, but they differ in properties and use cases. PLA (Polylactic Acid) is a biodegradable, easy-to-use material known for its low printing temperature and good surface finish, making it ideal for beginners. ABS (Acrylonitrile Butadiene Styrene) is stronger and more heat-resistant than PLA but can be harder to print with due to its tendency to warp. PETG (Polyethylene Terephthalate Glycol) combines the strength of ABS with the ease of PLA, offering good chemical resistance and flexibility, making it popular for functional prints. TPU (Thermoplastic Polyurethane) is a flexible, rubber-like material ideal for prints requiring elasticity, such as phone cases or wearable items, but it can be more difficult to print with due to its soft and stretchy nature.

How Long does Inventory Stay In Stock?

We try to keep hold of our inventory for as long as possible, but when it becomes clear that a product wont sell (~1 year), then we recycle or donate the component or product.

Can I Get Items For FREE?

Yes! If a product doesn't sell, The price will briefly become free before we can donate or recycle the product or component.
