MJF Nylon PA12 3D Printing UK

NYLON PA12 (MJF)

Strong, Durable & High Quality

Nylon PA12 MJF Introduction

PRODUCTION GRADE NYLON MATERIAL

Nylon PA12 via Multi Jet Fusion (MJF) 3D Printing process is constructed from fusing agents to Nylon PA12 powder. Unlike SLS, Nylon PA12 (MJF) does not require support for cavities and overhanging regions.  Nylon PA12 (MJF) is ideal for smoother, more watertight Nylon polyamide 3D print with higher density and lower porosity. Nylon PA12 (MJF) comes in two finishes: natural grey finish and dyed black finish.

MATERIAL APPLICATIONS

Nylon PA12 (MJF) is suitable for functional prototypes and end user parts that require good mechanical, thermal and chemical properties; such as engineering parts, housing, tools, jigs and fixtures. Due to its consistency and high quality output, Nylon PA12 (MJF) can easily be scaled up for low volume production of up to hundreds of parts within days. It is an ideal material to replace conventional injection molded parts.

DESIGN FOR MJF NYLON PA12

Wall thickness for 3D Printing

Minimum Wall Thickness

We recommend the following minimum wall thickness:

  • 1 mm (For Parts smaller than 10cm)
  • 2 mm (For Parts between 10cm-20cm)
  • 3 mm (For Parts larger than 20cm)

Parts with Sufficient wall thickness is crucial to ensure successful print.

Embossed and Engrave Details for 3D Printing

Embossed and Engraved Details

For Embossed Details: Recommended minimum thickness of 0.5mm and height of 0.5mm

For Engraved Details: Recommended minimum thickness of 0.5mm and depth of 0.5mm

Clearance for 3D Printing

Clearance for Fitting

Clearance is the space between two objects, allowing one or both of them to have a certain degree of freedom of movement relative to the other. We would recommend

  • MJF Nylon PA12: 0.15 mm (tight fit), 0.25 mm (standard fit) and 0.4 mm (loose fit).

You are advise to test out several iterations if you wish to attain a perfect fit.

Hollow 3D Printed Parts

Hollowing Model

It is highly recommended to hollow out solid models to reduce cost and avoid shrinkage issues. We recommend:

  • Wall Thickness of 2-3mm for Model below 35cm
  • Wall Thickness of 4-5mm for Model between 35-60 cm

Include ‘Escape Holes’ to your model so as to drain excess material. It is recommended:

  • At least 4mm ⌀ for smaller models
  • At least 8mm ⌀ for larger models
  • At least 2 holes
  • Add multiple holes for larger models

.

Warp 3D Printed Parts

Reduce Warpage

For models with large flat unsupported planes, there is a risk of warpage. To prevent this, consider adding ribs as reinforcement to combat this issue. 

Multiple Parts in Single File

Avoid Multiple Parts in a single file

Uploading multiple parts within a file may cause unnecessary delay in your order due to processing issues. Simply upload each part file separately for a smooth transaction.
