PolyCast™ is a filament designed to produce investment patterns for investment casting applications. 3D printing significantly cuts down both the cost and lead time by eliminating the tooling process.

This mateiral is a PVB material and does not need any special printer requirements to print.
Print slower than standard PLA. Recommended top Max Volumetric Speed of 15mm^3/s.
Increase printing temperature to 220˚C if printing at this fast 15mm^3/s.
Keep fan speed on at full blast for best surface quality. Reduce if noticing any layer adhesion issues.
The burnout temperature for our PolyCast is 1,100 - 1,200˚C to entirely burnout.
You can find more information on this on page 7 of our application notes for this material:

How do you use PolyCast™?
What makes PolyCast™ unique?
PolyCast™ features two unique technologies: Layer-Free™: PolyCast™ can be easily smoothed with IPA for a smoother surface finish which is reflected on the casted model. Ash-Free™: PolyCast™ burns out very cleanly with minimum ash residues.
Will the spools work in an AMS?
Yes! We have redesigned the edges of our spools so all Polymaker products will now spin great in the AMS.
Printing Requirements
None! This will print great on any stock 3D printer!
You will just want to print slower on stock, older style printers.
