If your new to the exciting world of 3D Printing there is a minefield of technical terms, materials and processes to consider. We have set our FAQ section to answer most questions.

If you have a question that isn’t covered on our FAQ’s please get in touch.

What clearance do you recommend for fitting parts?2018-03-12T09:19:54+00:00

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.

Does Graphite-SLS have anti-static properties?2017-04-04T14:29:25+01:00

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).

Are the materials certified food safe?2017-04-04T14:30:04+01:00

No, the materials have not been certified and therefore we would recommend avoiding contact with food or drink.

Are my files treated as confidential?2017-04-04T14:30:41+01:00

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.

Can I specify orientation of the part?2017-04-04T14:31:26+01:00

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.

Can I get any additional discount?2017-04-04T14:32:45+01:00

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 together. Shorter turnaround times and technical support are what we offer through Graphite Additive Manufacturing but costs are higher. There is a comparison chart on our homepage.

Can I combine parts together to reduce cost?2018-03-12T09:18:34+00:00

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.

Can I hollow a part to save cost or weight?2017-04-04T14:34:25+01:00

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.

What is the smallest hole size you can produce?2017-04-04T14:35:12+01:00

For short holes that are open both ends, around 2mm.

What is the minimum wall thickness?2017-04-04T14:36:07+01:00

All geometry should be at least 0.8mm thick to build. Ideally though, we’d recommend 1.2mm to give stronger parts.

What file formats do you accept?2017-04-04T14:36:49+01:00

STL files and we’d recommend a resolution set to 0.01mm. (Set to Binary rather than ASCII if you have the option)

What is the largest size of part?2017-04-04T14:37:35+01:00

We can 3D print parts up to 300mm long in one piece. If your part is larger, we may cut it and ship in sections. We would aim to cut the part in a sensible location and add features to aid gluing for you where possible.

What is the accuracy?2017-04-04T14:38:18+01:00

It will depend on the geometry, but we’d expect it to be in the region of +/-0.2mm

How quickly can parts be made?2017-09-29T17:17:34+01:00

Typically 7-21 working days depending on material and service selected.

Can you print in any other materials not listed?2017-04-04T14:39:41+01:00

No, as we are not using cheaper filament type machines, we cannot offer multi materials.

What is the difference in materials?2017-04-04T14:40:27+01:00

Graphite-SLS is a reinforced material with excellent performance to price ratio. The Carbon-SLS has the best stiffness to weight ratio of any 3D printed plastic. Both materials are slightly conductive. More information can be found at our other site here: Graphite-AM
