Nylon PA12 MJF 3D Printing Online

STRONG, DURABLE & HIGH QUALITY

Our MJF Nylon PA12, also known as HR PA12, is produced by HP Multi Jet Fusion Industrial 3D Printing Process. MJF Nylon PA12 have good thermal and mechanical properties suitable for functional prototypes, outdoor and end use applications. With comparable material characteristic as Nylon PA2200 via EOS SLS, both materials are interchangeable and complements well together.  It’s recommended for user to select whichever works best or provide the best and cost advantage.

HIGH QUALITY

Right out of production, this material is raw grey in texture. We provide bead blasting and black dyeing as a default finish to polish all our MJF Nylon PA12 giving it a polished matte black finishing. The current colour options available in this material is polished matte black or raw grey. For more aesthetic demanding applications, we can also provide further post processing to attain full gloss, near injection moulded aesthetic under our 2K spray painting services.

MJF Nylon PA12 Close Up

PROFESSIONALLY CRAFTED

Our MJF Nylon PA12 is professionally produced by renowned HP Multi Jet Fusion, also known as MJF Industrial 3D Printing Process. Using this process, parts are constructed by fusing nylon material with agents via a precisely controlled heat source. During the build process, parts are self-supported by surrounding nylon powder which enables the creation of complex parts without the worry of cumbersome support structures, allowing excellent freedom of design. The MJF process is well known for its high output debunking the myth of 3D Printing being slow and unscalable for end use production.

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

  • 0.15 mm (tight fit), 0.3 mm (standard fit) and 0.5 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.
