This section details the measurements needed to achieve your "desired fit", or as you may here us in the shop say: Tolerancing.
| Desired Fit | Clearance Gap (in) | Clearance Gap (mm) |
|---|---|---|
| Press Fit | 0 | 0 |
| Tight Fit | 0.005 | 0.127 |
| Normal Fit | 0.01 | 0.254 |
| Loose Fit | 0.02 | 0.508 |
Please make sure that any holes you have in your CAD model have the appropriate fit to them before printing! We have lost so much time printing useless 3D prints because a bolt could not fit through a hole. The reason? In CAD, the bolt had a press fit instead of a normal or loose fit. Verify the appropriate clearance gap exists in your parts before printing.

Slicing is the process of converting a CAD model into G-Code, which is executable code for CNC machines and 3D printers.

Valor uses Cura as our go-to slicing software. If you are installing Cura on your own computer, watch the following video for a quickstart on how to setup a printer, and how to edit your slicing configuration.

Regardless of if you are installing Cura on your own computer, or using the Valor Render Box in the shop, verify that the printer you are using matches the following setup:

If you are printing a part that has overhangs, requires additional slicing configurations, or seems a little more tricky than the common part, please see the Advanced section below for more details on additional setup.
