Woodworking Palette Knife

My Favorite Print Removal Tool

Removing a print from the bed of your 3D printer can sometimes be a harrowing experience. You wait for hours for the print to complete, maybe even dealing with a few failed attempts and then go on to break or mangle your print trying to get it off the printer bed.

My Lulzbot TAZ6 came with a nice little kit of tools but the print removal tool was basically a clam knife with a thick handle like a steak knife. I tried using that tool to remove my first print and it made the only gash I have in my PEI print bed. I then went on to buy a dedicated print removal spatula for about $8 on amazon. It was incrementally better — looks like a long frosting knife and was a little bit flexible, but was still thicker than I wanted and took some work to get a print off the bed. After looking at that tool I thought about some real nice palette knives I have in my woodworking tool kit that are flexible and machined down to the point that they are almost sharp.

I dashed out to the shop and grabbed one — the shape I least liked and least used for my woodworking was by far the best I’ve ever used for 3D print removals. (See photo above) That sharp corner and VERY thin edge is great for getting up under a print and quickly removing it.

Since I switched to using this tool with my printer I have not lost a single print due to issues getting if off of the bed. The knife tapers down to 0.008″ (twice the thickness of a human hair) at its thinnest and is about 1/16″ near the tang. This profile with a point off to one side (far right in photo below), along with the ability to easily flex the knife allows the user to easily pop printed items off of the bed. All I do is get the corner under the print and make a quick sweeping motion and the print comes right off the plate.

If you’d like to get a set of these useful palette knives you can find them at Lee Valley here. The set only costs $11.50 USD and should last a very long time. I also use them a lot for applying wood glue to my woodworking projects.

If you give them a try or have your own tips for consistently getting a print off the printer bed, please leave a note in the comments section below.

Take care,
