Available materials for MJF 3D printing
MJF produces parts from engineering thermoplastics. Here is the list of our standard MJF 3D printing materials.
Material | Description |
|---|---|
HP PA 12 (Nylon 12) | Nylon 12 is a robust thermoplastic with all-around excellent physical properties and chemical resistance, ideal for functional prototypes and end-use applications. |
Glass-filled HP PA 12 | Glass-filled nylon is reinforced with glass bead and creates parts with higher stiffness and thermal stability than standard nylon.
|
Available surface finishes for MJF 3D printing
Additional post processes can be applied to improve the appearance or mechanical properties of parts produced with MJF.
MJF parts with a wall thickness greater than 4 mm are watertight up to 20 bar without additional finishing.
Gray
Description
As printed MJF parts are typically gray in color and have a smooth surface, without visible layers, and a powder texture.
Dyed (black)
Description
MJF parts are dyed black by immersion in a warm color bath. The color penetration reaches a depth of about 0.5 mm and covers all surfaces.
Spray painting *
Description
MJF parts can be painted white, black or in a specified RAL or Pantone color.
Tumble smoothing *
Description
The parts are placed in a tumbler that contains small ceramic chips, gradually eroding its surface down to a polished injection molding-like finish.
* These finishes are available by contacting yanyan@Yanmisz.com.
Ideal MJF applications
Our in-house manufacturing experts recommend using MJF for the following use cases.
Functional prototyping
MJF is ideal for fabricating functional prototypes from durable, chemically resistant engineering thermoplastics.
Requirements
Strength: Medium/High
Appearance: Smooth surface
Quantity: 1 - 5 parts
Low-volume production
MJF is cost-competitive to injection molding for low-volume manufacturing of end-use plastics parts for quantities up to 300 units.
Requirements
Strength: Medium/High
Appearance: Injection molding-like
Quantity: 10-300 units
Design guidelines for MJF
The table below summarizes the recommended and technically feasible values for the most common features encountered in 3D printed parts.
Feature | Recommended size |
|---|---|
Unsupported walls | 1.0 mm (0.040'')
|
Minimum detail size | 0.25 mm (0.010'')
|
Supported walls | 0.7 mm (0.030'')
|
Minimum hole size | 1.0 mm (0.040'') |
Moving parts | 0.5 mm (0.020'') between moving surfaces |
Assembly clearance | 0.4 mm (0.016'') between mating surfaces |
Maximum wall thickness | 20 mm (0.8''). Thicker parts must be hollowed and contain at least two escape holes for powder removal with a min. diameter of 8 mm (0.3'').
