More possibilities for your Form 4
Move from prototyping to demanding industrial applications with three purpose-built materials, validated for a straightforward Open Material Mode workflow.
High stiffness + heat resistance
Ultracur3D® RG 3280
For demanding tooling, injection molding inserts and industrial applications where standard resins fall short.
Flame retardant
Ultracur3D® RG 9400 B FR
For electronics housings, industrial fixtures and components in demanding thermal environments.
Dissolvable tooling
Ultracur3D® xMOLD
For rapid Freeform Injection Molding with complex geometries and without conventional metal tooling.
At a glance
Find the right resin for the job
| Material | Best for | Key performance | Typical applications |
|---|---|---|---|
| RG 3280 | Rigid, heat-resistant tooling | HDT > 280 °C | Injection molding inserts, wind-tunnel parts, fixtures |
| RG 9400 B FR | Flame-retardant components | UL 94 V-0 at 2 mm; HDT 255 °C | Electronics housings, industrial fixtures, thermal environments |
| xMOLD | Dissolvable injection molds | Rapid, residue-free dissolution; up to 90% lower tooling cost | Bridge tooling, complex molds, low-volume injection molding |
Tooling and high-temperature applications
Ultracur3D® RG 3280
Ceramic-like stiffness and exceptional heat resistance for demanding tooling and industrial applications.
- High mechanical stiffness for tooling and industrial parts
- Heat deflection temperature above 280 °C
- Suitable for injection molding inserts and wind-tunnel testing
- Low viscosity supports easier handling, faster recoating and lower sedimentation risk
Flame-retardant industrial components
Ultracur3D® RG 9400 B FR
A UL 94 V-0 flame-retardant resin combining strong mechanical, thermal and chemical performance.
- UL 94 V-0 rated at 2 mm
- Almost 2× higher tensile strength than comparable FR resins
- 25% higher stiffness
- More than 2× higher heat resistance: HDT 255 °C versus 111 °C
- Improved chemical resistance
Freeform Injection Molding
Ultracur3D® xMOLD
A dissolvable mold resin for producing real injection-molded thermoplastic parts without the cost and lead time of conventional metal tooling.
- Fast and reliable Freeform Injection Molding workflow
- High dimensional accuracy and rapid, residue-free dissolution
- Enables complex mold geometries that conventional tooling cannot achieve
- From CAD to molded part in days, with tooling costs reduced by up to 90%
- No equivalent in the standard Formlabs material portfolio
