Grey Pro Resin

Formlab’s Grey Pro Resin is a great alternative to Standard Resin when printed parts need to be mechanically stronger. Grey Pro works great for large prints that need high precision, moderate elongation and low creep. It’s also a great material for printing small jewelry prototypes, the enhanced mechanical properties of this material ensures important features on small prints do not break.

PROS OF

Grey Pro Resin

When it is a perfect material choice

Great for concept modeling

Works great for prototyping jewelry parts that do not need to be casted in metal

Use Grey Pro for Standard Resin prints that need more strength

Ideal for plastic and silicone mold masters

CONS OF

Grey Pro Resin

When to seek other material options

Prints with supports that need to be removed and sanded

Not great with chemical resistance

No custom color options available

Not available on SLA XLbuild volume

PRINT SETTINGS

You need 3D printing and you need it FAST! That’s why we offer some of the quickest turnaround times in the nation.

QUALITY FOR

Grey Pro Resin

This number of microns determines how thick each layer is. The smaller the micron count, the thinner the layer, this results in higher surface detail, better surface finishes and less stepping!
