Composition
Formlabs General Purpose Resin is tailored for SLA 3D printing. Emphasizing a balance between mechanical strength, ease of use, and aesthetics, this resin is ideal for a broad range of applications, from prototyping to artistry. Boasting a smooth finish, impressive detail capture, and various colour options, it stands as a top choice for professionals and enthusiasts alike.
Physical Properties
- Density: Typically around 1.1–1.2 g/cm³
- Tensile Strength: Generally in the range of 40-55 MPa, depending on the post-curing process
- Heat Deflection Temperature: Usually falls between 50-70°C after post-curing
Aesthetic Quality
Formlabs General Purpose Resin produces prints with a smooth surface finish and is available in various colors, including clear, white, and grey. The material captures fine details well and offers good dimensional accuracy, making it suitable for both aesthetic and functional parts.
Durability and Usage
Designed for a wide range of applications, this resin offers moderate tensile strength and thermal resistance, making it versatile enough for prototyping, art projects, and some functional parts. While it may not match specialized resins in mechanical properties, it provides a good balance for general-purpose printing.
Post-Processing
The post-processing steps include washing the print in a solvent (usually isopropyl alcohol) to remove any uncured resin, followed by UV curing to improve its mechanical properties. The material can be sanded, drilled, and painted, and generally adheres well to common types of adhesives and coatings.
Environmental Impact
Like most SLA resins, Formlabs General Purpose Resin is not biodegradable and should be handled and disposed of responsibly to minimize its environmental impact. The resin is also not derived from renewable resources, making it less eco-friendly compared to bio-based materials like PLA.
In summary, Formlabs General Purpose Resin offers a versatile, well-balanced material suitable for a wide array of SLA 3D printing applications. Its moderate mechanical properties and good aesthetic qualities make it a popular choice for both professionals and hobbyists for a variety of projects. Although it isn’t the most eco-friendly material, its flexibility and general ease of use make it a valuable option for those who require a multi-purpose resin.
