Forust™

 

 

Powered by Desktop Metal®’s binder jetting 3D printing technology, Forust is a sustainable alternative to traditional wood manufacturing. It is now possible to produce isotropic, high-strength, and sustainable wood parts for many industries while helping in building a greener and sustainable future.

• Minimum part size: 50 x 50 x 6 mm
• Maximum part size 320 x 200 x 150 mm
• Fill per cent > 10.0% (part volume/bounding box volume)

• Minimum wall thickness 5.0 mm
• Minimum feature opening/aperture size: 5.0 mm
• Engraved features: 2.0mm deep
• Embossed features: 2.0mm high

• Try to avoid thick-to-thin structures.
• Minimum wall thicknesses are a guide only for large pieces walls should be thicker.
• Where possible, split parts into flat sections for printing.
• Add features to parts for assembly.
• For parts that fit together, allow 1.0 mm clearance.
• Cantilevered struts should be less than 20.0 mm long.
• No snap fit features
• No moving parts.
• For hollow parts, the part must have an opening for powder removal that is at least 20 mm diameter.

• Minimum point size for raised text: 36 point or 12.7 mm
• Minimum point size for engraved text:36 point or 12.7 mm

• Material: Wood powder mixture of hardwoods with bio-based epoxy resin.
• Flammability: The material will burn.
• Flexural Strength: 40 MPa
• Tensile Strength: 28 Mpa
• Modulus: 3.6 GPa
• Flexibility: Some
• Texture: Grainy surface that is slightly smoother with matte, satin and gloss finishes
• Food safe: NO (if food safety is required food safe resins can be used)
• UV Resistant: NO (UV-resistant coatings can be applied)
• Heat resistant: NO
• Watertight: There is some residual porosity. Parts can be made watertight with a coating

 

*Due to the nature of finishing by spraying, some complex geometries may have areas where there is no surface finish. Subsequent coats of lacquer and water-based finishes may slightly change the dimensions of the parts.
