Polyurethane 3D Printing Resins

Produce tough, durable, and long-lasting parts with our Polyurethane Resin family. Break free of the limitations of traditional polyurethane manufacturing with newfound design freedom, reduced production costs, and improved workflow efficiencies. Reduce 3D printing overhead costs with fewer tool changes, setups, and re-prints by leveraging parts ready to withstand repeated functional use and testing

Ideal for:

High performance automotive, aerospace, and machinery components
Robust and rugged end-use parts
Tough, longer-lasting functional prototypes

3D Printing Workflow with PU Resins

Polyurethane Resins have a longer workflow requiring additional equipment and set-up costs. More attention and time are needed when setting up your prints and post-processing your parts to get consistent, high-quality results. 

Step 1: Produce 3D File
Step 1

Produce 3D File

Generate your print file in PreForm with proper supports, orientation, and layout. Send the file to the printer.

Step 2: Prepare the Printer
Step 2

Prepare the Printer

Fill the self-dispensing cartridge with the PU resin. Insert the cartridge into the printer, which is located in a dry cabinet. Load your Build Platform and Resin Tank.

Step 3: Print
Step 3


Follow the prompts on the easy-to-use touchscreen to get your print started. 

Step 4: Post-Processing
Step 4


Place Build Platform in a brief PGDA wash, then allow parts to air dry or use an air compressor. Remove parts from the platform and from supports. When dry, set the parts in the humidity cure chamber for a minimum of a couple days of post-curing.

Handling & Safety

Handling & Safety

Resin should be handled with care. Proper handling will ensure safe printing and efficient use. Our resins have been designed to be similar or safer to handle as other household chemicals or adhesives. Formlabs materials do not contain volatile solvents so special ventilation is not required. Skin contact should be avoided.

The Safety Data Sheets (SDS) are up to date for every resin product and follow the latest government guidelines. Always consult the SDS as the primary source of information to understand safety and handling of Formlabs materials. For more information about handling resin, learn more tips for resin maintenance in our Help Center.
