MATERIALS.
PA12 - Polyamide (nylon 12)
Strong & Durable | Watertight | Chemical Resistant | 80% Powder Reusability
Polyamide 12 is the main material we use, it is extremely versatile so can be used for a wide range of applications from enclosures down too custom fasteners. Specific additive design techniques such as internal lattices and variable shell thickness can be used achieve further attributes.
KEY PHYSICAL PROPERTIES
Tensile Strength: 48 MPa
Tensile Modulus: 1800 MPa
Flexural Modulus: 1730 MPa
Heat Deflection: 175° C
PA12 DESIGN TIPS
Minimum wall thickness 1mm. Down to 0.5mm in small areas.
Max wall thickness: 8mm. We can print large solid models but will recommend that we hollow or add lattice to reduce the chance of dimensional inaccuracies such as warping or sinkage.
Minimum gap between surfaces not to be fused should be 1mm. Smaller gaps can be achieved between tangent surfaces.
Large flat surfaces can may distort, especially with variable wall thickness.
Sudden changes in thickness may lead to distortion.
The Adams Engineers and Equipment inc, have a very useful handbook on design for MJF.
As part of our added value service we provide free design feedback and advice on achieving desired aesthetic and mechanical properties. Unless specified we will print the model in the orientation that we believe will bring the best finish.
