Formlabs also recently introduced a new 3D printing resin specifically designed to withstand higher temperatures.

We recently collaborated with Formlabs on a technical paper they published, detailing how their 3D printers can be used to make prototype injection molds.

You can download the paper directly from their website here.

Here’s a webinar from Formlabs that talks about how 3D printed molds can be used for short-run injection molding.
