I had this idea to 3D print on canvas a few weeks back. So while my wife and I were at Hobby Lobby the other day I decided to grab a pack of small 4" by 4" square canvas. I removed the glass print bed on my printer and taped down the canvas in the middle of the print area. After finding what I wanted to print on the canvas, I set my printer to print just a few mm above the canvas so I could make adjustments in the print code for the location of the canvas on the bed. Then I set the print nozzle close to the canvas to push the melted plastic into the fibers of the canvas. I used a 0.35mm nozzle but smaller nozzles can be used to get greater detail, such as a 0.25mm nozzle. Dual extruders can be used for two colors and/or two materials, which would greatly improve future possibilities.
Final Product!
BLAM!
