-The Fresh Prints of 3D

You can do some pretty neat stuff with just a glass bed and some painter’s tape.

Here’s how it works.

  • Printing on a glass bed gives a smooth, glossy bottom layer.
  • Printing on painter’s tape gives a textured, matte bottom layer.

Apply painter’s tape to the glass bed, then cut some designs into the tape with an Exacto knife to create an artistic matte vs. gloss contrast.

Step 1: Clean Your Glass Bed

Step 2: Tape And Cut

Step 3: Print And Peel


  • Make sure you’re print bed is perfectly level. This has a tremendous impact when printing large flat pieces.
  • Thoroughly clean your glass bed before printing. A little acetone, a few paper towels, and some elbow grease go a long way.
  • Use a large layer height for the bottom layer. I often go with 0.35 mm – 0.4+ mm. This helps offset the height difference between tape and glass.
  • Use a wide extrusion width for the first layer. I usually go with 200% (computed over height) in my Slic3r settings.
  • Sketch your design on the masking tape in pencil before cutting it away. An eraser is your friend.
  • If you have access to a laser cutter, you can try cutting your design with that. It will be more precise than you will be by hand.
  • Apply a light solution of Elmer’s glue in water to your glass bed to ensure the layer sticks.
  • Get creative! Experiment with the process. It’s what 3D printing is all about.
