    Desktop Metal FORUST wood 3d printing logo



    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.
