STRONG, DURABLE & HIGH QUALITY

Our MJF Nylon PA12, also known as HR PA12, is produced by cutting edge HP Multi Jet Fusion 5200 Industrial 3D Printing Process. This material will have excellent thermal, chemical and mechanical properties. It is also certified for biocompatibility, FDA skin contact and IP rated water tightness, making it 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 MJF for dark colour parts and EOS SLS for light vibrant coloured parts. Ultimately, whichever works best or provide the best and cost advantage.

HIGHEST QUALITY

Right out of production, this material is raw grey in texture. We provide DM polyshot surfacing 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 cosmetic demanding applications, we can also provide further post processing to attain full gloss, near injection moulded aesthetic under our 2K spray painting services.

PROFESSIONALLY CRAFTED

Our MJF Nylon PA12 is professionally produced by renowned HP Multi Jet Fusion 5200 system, 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 highly accurate and 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 PLASTIC

Minimum Wall Thickness

We recommend the following minimum wall thickness:

1 mm (parts ≤ 10 cm)
2 mm (parts between 10 cm to 30 cm)
3 mm (parts ≥ 30 cm)

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 Fitting

It is very important to allow clearance between the space of 2 objects, so as to give a freedom of movement between the gap. We recommend:

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

You are advised to test out several iterations to attain a perfect fit.

Hollowing Model

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

Wall Thickness of ≥ 3mm for model below 35cm
Wall Thickness of ≥ 4mm for model between 35 to 60 cm

‘Escape Holes’ may be added to your model to drain excess material.

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.

Add ribs in moderation, adding them excessively may result in uneven cooling and further accelerate warpage.

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.
