Formlabs Fast Model Resin (Form 4) - 1L is the definitive high-speed material for the Low Force Display (LFD) print engine, capable of print speeds exceeding 100 mm per hour. This resin is specifically formulated to allow for the rapid production of dental models, orthodontic appliances, and high-fidelity prototypes with exceptional surface quality. Consequently, it represents a significant advancement over legacy Draft resins, providing the ideal balance of speed and precision for Australian laboratories and engineering firms requiring immediate physical iterations.
Maximum Throughput with Formlabs Fast Model Resin (Form 4) - 1L
The Formlabs Fast Model Resin (Form 4) - 1L leverages the high-intensity light source of the Form 4 to cure layers in seconds, dramatically reducing total lead times. This material is validated for 200-micron layer heights for maximum speed and 100-micron heights for applications requiring finer detail. Furthermore, the resin maintains high dimensional stability throughout the post-curing process, ensuring that orthodontic models and mechanical prototypes fit correctly every time without the risk of warping or distortion.
Technical Performance and Material Properties
Whilst speed is the primary objective, the material properties ensure that parts are robust enough for handling and vacuum forming. The following properties are achieved after a 5-minute post-cure at 60°C:
| Mechanical Property | Value (Post-Cured) |
|---|---|
| Vertical Print Speed | > 100 mm/hour |
| Ultimate Tensile Strength | 47 MPa |
| Tensile Modulus | 2.3 GPa |
| Flexural Modulus | 2.0 GPa |
| Heat Deflection Temp @ 0.45 MPa | 73°C |
Streamlined Post-Processing for Fast Model Resin
The Formlabs Fast Model Resin (Form 4) - 1L workflow is designed to be as efficient as the print itself. Parts require a brief 5-minute wash in Isopropyl Alcohol (IPA) followed by a short cure cycle. Because the material is highly reactive, it is essential to store the cartridge away from direct sunlight and within the recommended temperature range to preserve the shelf life. This resin is an essential tool for any professional workspace prioritising rapid prototyping and high-volume model production.
