Composition
Formlabs Castable Wax 40 Resin is specifically formulated for SLA 3D printing. Ideal for high-detail lost-wax casting in jewelry and dental sectors, this resin ensures precision and easy burnout, capturing intricate details effortlessly.
Physical Properties
- Density: Generally ranges between 1.05–1.15 g/cm³
- Tensile Strength: Typically around 20-35 MPa, depending on post-curing processes
- Melting Point: Lower than standard resins, designed for easy burnout without ash residue
Aesthetic Quality
Formlabs Castable Wax 40 Resin produces prints with a smooth and high-quality surface finish, often available in blue or violet shades to assist in visual inspection. The material is excellent for capturing intricate details, making it ideal for applications requiring a high level of precision.
Durability and Usage
While the material is designed for its castability rather than durability, it offers sufficient strength for handling, assembly, and short-term use. It is optimized for producing patterns for lost-wax casting, particularly in the dental and jewelry sectors, where highly detailed casts are often required.
Post-Processing
The post-processing steps typically involve washing the print in a solvent, usually isopropyl alcohol, to remove uncured resin, followed by UV curing if necessary for handling. Subsequently, the printed object is used to create a mold, which is then subjected to high temperatures to burn away the resin, leaving a cavity for casting metal or other materials.
Environmental Impact
Like most photopolymer resins, Formlabs Castable Wax 40 Resin is not biodegradable and should be disposed of responsibly to minimize its environmental footprint. It is synthesized from non-renewable resources, making it less eco-friendly than bio-based materials.
In summary, Formlabs Castable Wax 40 Resin offers a specialized material tailored for lost-wax casting applications, particularly in the jewelry and dental industries. While its environmental impact is a consideration, its unique casting capabilities and high-detail resolution make it invaluable for specialized projects. Proper handling and disposal are crucial given its environmental impact.
