What clearance do you recommend for fitting parts?
We would recommend a 0.1mm clearance in the design for assemblies. If you are wishing to combine parts together for building, then leave at least a 1mm gap.

The considered “safe” range for materials (between Conductive and Dissipative) is 100k Ohms – 35M Ohms. We have measured Graphite-SLS to be within this range at 280k – 485k Ohms. (Carbon-SLS is 20k – 100k).
No, the materials have not been certified and therefore we would recommend avoiding contact with food or drink.
Yes, this is extremely important to us. We understand that the majority of parts we see are a new product design or prototype. Confidentiality for our customers is critical. We have industry standard security on site, and we will not release images or any data without customer approval.
If you pre-orientate the part as you would like it built, it would normally be kept in this orientation. However, we may change the orientation for nesting optimisation.
The prices on 3D Print Direct are already heavily discounted and close to cost price. The only way we can keep part price so low is to be able to 100% pack our machines with parts and having a semi automated ordering process. By having longer lead times we can more efficiently pack many orders [...]
Yes you can with this service, but in some cases it can increase the cost. We may choose to build and ship the parts contained in a sinterbox (cage). This may restrict our ability to clean powder from the parts compared with cleaning components individually. For merged parts, leave at least a 1mm gap.
Hollow parts will save weight but normally do little to reduce cost. We will need plenty of access to be able to remove and clean the loose powder out of the cavity. At least 2 holes, (one at each end) that are at least 1/4 the size of the cavity.
For short holes that are open both ends, around 2mm.
All geometry should be at least 0.8mm thick to build. Ideally though, we’d recommend 1.2mm to give stronger parts.
