Some frequently asked questions about the SLS process and designing  for SLS printing:

Is laser sintering (SLS) only for making prototypes?

No. For example, thousands of our parts have been produced as production parts for installation on UAVs. These parts have amassed over 800,000 hours of flight time.

Can SLS parts be produced overnight and delivered within 24 hours?

Technically, yes. There have been special circumstances under which we were able to deliver local orders within 24 hours, but that is not the standard. We will inform you of our turnaround time when you submit a quote or if you contact us.

What is the correct name for the Selective Laser Sintering (SLS) process?

There are a variety of terms. The Industry has taken steps to promote the term "Additive Manufacturing" as a standard. Other terms include: 3D Printing, SLS Manufacturing, Additive Manufacturing, Rapid Manufacturing, Selective Laser Sintering, SLS Prototyping, Rapid Prototyping, Short Run Manufacturing, Limited Run Manufacturing, 3D Prototyping, Direct Digital Prototyping, Direct Digital Manufacturing, Desktop Fabrication.

Can I print any design?

Almost; some designs are better than others. Please email your CAD file and we will let you know if there are any concerns.

Is there a way to make parts FDA-compliant, for use with food?

Yes! Our Nylon 12 material PA2201 is FDA-compliant for direct contact with food.

Are SLS Materials RoHS Compliant?

Certain materials are restricted for use in newer electronic and electric equipment. Consult the RoHS (Restriction of Use of Hazardous Substances) regulations Statement of Compliance – RoHS and WEEE Directives for more information.

Is Northwest Rapid Manufacturing ITAR registered?

Yes! We are able to enter into ITAR compliance agreements as necessary.

Are Biocompatibility Certificates available for the materials used in the SLS process?

Yes. NWRapid has a Biocompatibility Certificate on file for PA2200, a Nylon 12. This certificate can be provided upon request, by contacting us at
