Composition
Formlabs PU Rigid 1000 Resin displays unique properties as a polyurethane-based photopolymer tailored for SLA 3D printing. Renowned for its unmatched rigidity and tensile strength (75-90 MPa), it’s an optimal choice for demanding applications like structural components and precision molds.
Physical Properties
- Density: Generally falls within the range of 1.2–1.3 g/cm³
- Tensile Strength: Exceptionally high, often in the range of 75-90 MPa, depending on post-curing treatment
- Heat Deflection Temperature: Remarkably high, frequently exceeding 110°C after post-curing
Aesthetic Quality
Formlabs PU Rigid 1000 Resin produces prints with a smooth, high-quality surface finish. The material is typically available in neutral or light colours, making it suitable for both functional components and aesthetically pleasing models. Its ability to capture fine details makes it ideal for intricate designs.
Durability and Usage
This resin is engineered for applications that require extreme rigidity and low deformation under load. It is particularly suitable for structural components, engineering models, and high-precision molds. The unique blend of polyurethane resins and reinforcing additives provides unparalleled stiffness, making it one of the most rigid materials in the Formlabs lineup.
Post-Processing
The post-processing steps generally involve washing the printed object in a solvent like isopropyl alcohol to remove uncured resin, followed by UV curing to maximize mechanical properties. The material can be sanded, machined, and painted, although specialized adhesives and coatings may be necessary for optimal results.
Environmental Impact
As with most SLA resins, PU Rigid 1000 is not biodegradable and requires special disposal methods to minimize its environmental impact. The material is also derived from non-renewable resources, making it less eco-friendly compared to bio-based materials like PLA. Responsible use and disposal are essential for mitigating its environmental footprint.
In summary, Formlabs PU Rigid 1000 Resin offers a specialized material that excels in rigidity and strength, making it ideal for a variety of challenging industrial and engineering applications. While its environmental impact is a consideration, its advanced performance characteristics make it invaluable for specialized, high-stress applications. Responsible handling and disposal are essential given its environmental impact.
