Create molds around parts printed with these filaments. They’re PVB, so they vaporize cleanly from your mold, similar to wax in traditional investment casting and lost wax casting. For a smoother surface on your mold, before casting you can apply isopropyl alcohol to remove the layer lines from your printed parts. Apply using a brush, sprayer, or vapor bath.

Tensile strength is the best measure of a filament’s overall strength. Similar to the stress applied on a rope during a game of tug-of-war, it’s the amount of pulling force a material can handle before breaking. A higher rating means a stronger filament. A tensile strength of 5,000 psi and above is considered good; 12,000 psi and above is excellent.

Maximum exposure temperature is the point at which a printed part will begin to deform. Above this temperature, your part will start to lose structural integrity.
