Validating your dimensions

Our online tools can verify that most of the dimensions of the parts you upload will meet the minimum requirements. However, in some cases it will still be possible for you to place an order with an unprintable model. We may notice these issues during production planning, and in this case we'll inform you and cancel the order. Once the print is initiated, it's impossible for us to offer a refund even if the taks fails and produced a defective item.

 

Be sure your model is designed within the following limitations:

Large parts

Parts that are larger than the printing area of our machines will be split into sections and assembled. Let our team know if you need the part to be cut in a certain way.

Details and features

If your part has internal channels or other important features, please inform our production team so they're careful with these details while preparing the parts.

Printing failures

As mentioned above, it's not possible to issue refunds once the materials have been used. Printing failures are rare but also very costly in terms of both material and time. In some cases, we can advise you as to what changes you'll need to make to your model to ensure a successful print. We can also recommend different printing technologies that may give better results with your design, but this isn't always an option. In any case, the costs of printing replacements will be added to your original order.

Effects of solvent smoothing

We've recently added a new solvent smoothing option for nearly all the materials we offer with SLS and FDM technology. While performing tests, we observed a very small reduction of thickness at the surfaces of the parts. This is caused by the solvent melting the surface material, then re-hardening it as a slightly denser layer. While this can improve the mechanical properties of the part, it also means some critical dimensions may be affected. It's therefore imperative to mention these important details when you place your order.
