3D Printing On Top Of Laser Cut Acrylic

Julius Curt sought a more precise marking method for acrylic panels than traditional rastering. Experimenting with direct 3D printing onto acrylic sheets, he discovered a successful approach. To securely hold the sheet during printing, he initially considered gluing it to the bed. However, he opted for a cleaner and safer method.

The bond between 3D prints and acrylic is exceptionally strong. To facilitate the process, Julius created a 3D model consisting of a constraining “fence” to enclose the panel and the desired artwork floating above. He paused the print mid-way to insert the pristine panel after building the fence. A quick re-prime and wipe ensured a smooth transition.

The video offers valuable insights. To maintain adequate tolerance between the fence and panel, it’s crucial to consider the layer width, associated tolerance, and laser kerf of your machine. Additionally, the hot nozzle can damage the acrylic surface during travel moves, making Z-hopping essential.

This technique can be further utilized to fully integrate an acrylic sheet into a print. By pausing at the appropriate height, dropping the panel, and continuing the print with an overlapping section, the plastic bonds very firmly to the acrylic, as demonstrated by Julius in the video.
