The 27-May 3D Printer Workshop at CTH went well. Our new pal Josh brought in his older AirWolf 3D AW3D XL printer. This thing has a huge 200×300 mm heated build plate. However, the build plate was a PCB-style which flexed and warped when heating up. This gave an inconsistent print surface height. If you’ve printed before, you know the height of the print surfaces has to be pretty darn consistent to get first-layer adhesion. Josh bought a replacement aluminum build plate, but unfortunately, the mounting holes were not the same! We can fix that…
The build plate bolts directly to an aluminum frame. We removed that frame from the printer, clamped the new build plate to the frame and transfer-drilled new mounting holes in the frame. After that modification, re-assembly was a breeze.
Along the way, an aluminum standoff was lost. Instead of heading to the hardware store, we just machined a replacement here out of some scrap aluminum. Having the tools and supplies to keep your project moving forward is one of the benefits of belonging to a hackerspace.
The new build plate came with a new thermistor and power wires. We swapped the connectors from the original, ran the new wires through the original wire loom and Bob’s your uncle. This AW3D XL now has a new and improved heated build plate that looks like it came that way from the factory.
