Introduction
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.

Size of Parts
- 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)
-
Walls and Features
- Minimum wall thickness 5.0 mm
- Minimum feature opening/aperture size: 5.0 mm
- Engraved features: 2.0mm deep
- Embossed features: 2.0mm high
-
Other Design Guidelines
- 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.
-
Text
- 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 Properties
- 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.
