See-Through Casting Compounds
Create transparent molds to monitor fill levels, differentiate parts at a glance, and avoid damaging parts when cutting the mold away. These casting compounds are two parts that activate when mixed.
Urethane compounds are tougher than silicone compounds, so your molds will last longer. Although not required, curing urethane molds inside a vacuum chamber improves their clarity. By removing trapped air bubbles, the chamber prevents the finished mold from looking speckled.

Flexible 3D Printer Resins
Stretchy, soft, and sturdy, these resins make durable parts that resist breaking from repeated use. They’re often used to create long-lasting parts, such as seals, sleeves, and gaskets. These resins are also good for making springs, snap-fit parts, and other components that handle high impact. Print them on a digital light processing (DLP), stereolithography (SLA), or LCD 3D printer.
Tensile strength is the best measure of a resin’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 resin.
Elongation is the amount of stretching that a material can withstand before breaking. Resins with a low elongation can break suddenly under load, while resins with a high elongation will deform before breaking. The higher the percentage, the more your part will deform before breaking.

High-Temperature 3D Printer Resins
Parts made from these resins remain strong and rigid in temperatures that would soften most plastic, so they're often used near ovens, engines, and other hot machinery. They're a good lightweight alternative to machined metal parts. Print them on a digital light processing (DLP), stereolithography (SLA), or LCD 3D printer.
Ceramic-filled resins are the stiffest in our 3D printer resin offering once cured. Use them in parts that need to remain stable and not stretch under heavy loads.
Tensile strength is the best measure of a resin'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 resin.
Elongation is the amount of stretching that a material can withstand before breaking. Resins with a low elongation can break suddenly under load, while resins with a high elongation will deform before breaking. The higher the percentage, the more your part will deform before breaking.
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.

Impact-Resistant 3D Printer Resins
Bumps, scrapes, and falls won’t damage parts made from these tough resins because they absorb impact without cracking or breaking.
