Materials » Polyamide

Models in polyamide are constructed from a white, very fine, granular powder. The result is a strong, somewhat flexible material that can take small impacts and resist some pressure while being bent. The surface has a sandy, granular look, and is slightly porous.

Pricing info

  • All designs that fit within a bounding box of 125 cm³ and have a maximum dimension of 200 mm comes at 12,75€ a piece.
  • If your design fits within a bounding box of 27 cm³ (for example 30 x 30 x 30 mm) and has a maximum dimension of 100 mm, you’ll only pay 5,1€ per copy of that same design (for example you’ll pay 33,15€ for 5 copies as 12,75+5,1+5,1+5,1+5,1 = 33,15)
  • For copies of any other design that still fits within the 125 cm³ and have a maximum dimension of 200 mm, you will pay 10.2€ per copy (for example, you’ll pay 53.55€ for 5 copies as 12,75+10.2+10.2+10.2+10.2 = 53,55)

Typical use

Polyamide can be used for complex models, concept models, small series of models (several copies of a model), lamps, and functional models. This technique allows the greatest freedom of design of all 3D printing techniques.

Technology

MaterialOverview_TechnologyAltImage

Selective laser sintering is used to build your design with this material. The models are printed layer by layer by a laser that draws thin lines in the powder, which melts and bonds it together in order to form a thin layer of the model. After a layer is printed, a new layer of fresh powder is spread over the surface by a roller. The printer has a print chamber that is heated to just below the melting point of the powder; the laser beam adds the extra energy to melt the powder, forming a solid model. After a print job is finished, the result is a big block of heated powder with the printed models contained inside.

Additional information

  • Polyamide is a material that is perfect for beginning-designers who want a well-priced model, a maximum freedom of creation, and who don’t want to be bothered with the limitations of the printing process.
  • Polyamide models are not suited for outdoor use as they absorb moisture. However, in some cases the material can be treated to make it watertight.
  • Be careful for models with large, flat surfaces or plates (<25 cm). When such a model cools down, it can deform. The deformation process is known as warping.
