3DFashion - Wet Marks

Wet Marks Appear Around or Behind 3D Print

PQ - wet marks 1

Wet marks appear on the fabric around the 3D print or behind it. This is called wetting effect.

Possible Causes and Solutions

Flex Touch Coating is Applied in Between the Elements

The Flex Touch coating Full option applies a coating layer to the top surface and in between the elements of the 3D print. This increases the contact area between the Flex Touch coating and the fabric surface.

Solution 1: Print the Fabric Analyzer and follow instructions as described in the relevant best practice guide Printing on Fabric with J850 TechStyle - EN PolyJet Best Practice

Solution 2: Apply the coating layer only to the top surface of the 3D print to reduce the contact area by selecting the Flex Touch Smart coating option in GrabCAD Print.

Notes:

  • This reduces the wetting that appears around the 3D print, but it does not prevent wetting. The appearance of wetting can be reduced with a thicker fabric.
  • If you do not use the Flex Touch coating option, the 3D print may feel sticky when you use flexible printing material.

Type of Geometry and Flex Touch Coating

The type of geometry of the 3D print along with using Flex Touch coating can affect the level of wetting on the fabric.

For example, the left image is a 3D print with a fully-segmented geometry, and the right image shows a high level of wetting from the Flex Touch coating on the back of the fabric:

Solution 1: Print the Fabric Analyzer and follow instructions as described in the relevant best practice guide Printing on Fabric with J850 TechStyle - EN PolyJet Best Practice

Solution 2: Change the geometry to reduce the wetting effect.

For example, the left image is a 3D print with a partially-segmented geometry, and the right image shows a low level of wetting from the Flex Touch coating on the back of the fabric:

 Sparse Geometry

The design has a few elements that are not close together.

Solution 1: Print the Fabric Analyzer and follow instructions as described in the relevant best practice guide Printing on Fabric with J850 TechStyle - EN PolyJet Best Practice

Solution 2: Use a dense geometry design (many elements that are close together).
