Silicone & Rubber Parts Production With 3D Printing
Producing soft or flexible parts in small batches can often be difficult, time-consuming, and expensive. To overcome these limitations, many engineers and manufacturers are now turning to 3D printing to create rapid molds for casting silicone, or even to directly fabricate flexible components. 3D printers provide key advantages like CAD-based design freedom, high precision, fast iteration cycles, and minimal lead times.




3D Print Using Real Silicone
Reduce outsourcing and hand-molding of silicone, urethane, and rubber parts. Lynxter and Formlabs printers and materials offer several routes to create complex, short-run flexible and elastic prototypes—and even end-use parts—in house, in hours.

3D Print Moulds to Inject Silicone
Stop waiting weeks for tools to arrive from a service provider or for your CNC machine to free up. With in-house 3D printing, you can create custom jigs and fixtures within a day, run tests, tweak your design, and print again.

Step 1
Design
Model your mold in CAD. Depending on geometry, choose a compression mold, injection-filled mold, overmold, or eggshell mold.

Step 2
3D Print
Select the right resin from the materials library and print the mold on a Formlabs SLA printer.

Step 3
Fill the Mold
Prepare the tool with protective coatings and release, then mix your silicone and fill the mold.

Step 4
Post-Process
Demold, trim, and finish the silicone part as needed. For full instructions, see the white paper.
