Injection Moulding Materials

Proper material selection is critical in prototyping and low-volume part production. You should consider the mechanical properties, mouldability characteristics and cost of the material.

If you choose to supply your own resin for injection moulding, please complete this customer-supplied resins form, which requires you to upload the resin’s MSDS and process data sheet documents. A representative from Proto Labs will contact you with shipping information and a material ID number once your information has been processed.

For additional information on the material strength, resistance, dimensional stability and other characteristics of Proto Labs’ frequently used thermoplastics, download our Resin Guide PDF.
