Aluminum Heated Build Plate for 3D Printer

thingiverse

The aluminum heated build plate, measuring 200 x 200 mm, is designed for use with typical 3D printers featuring MK2, MK2A, or MK2B heat bed PCBs. Made from 4mm thick T6061-T6 aluminum alloy, it ensures flatness and resists twisting. The plate uses countersunk mounting screws to avoid damage from the hot end and features a milled channel for concealed thermistor installation. Anodized aluminum plate kits are available for purchase at various online stores. Key design features include a 4mm-thick scratch-resistant surface, hidden countersunk mounting screws, high-temperature resistant silicone rubber spacers instead of springs, and a concealed thermistor in the milled channel on the bottom. For DIY enthusiasts, instructions are provided to build the plate using drawings, a BOM, and recommended materials from OnlineMetals.com. Cutting aluminum can be challenging without CNC mill or router; however, a 1/8" material is still suitable. G-code generation from STL or STEP files is possible with CAM software and a 2-flute endmill at high rpm. Hardware can be sourced from McMaster.com using the provided part numbers. A connecting bridge for MK2B and mounting hardware for the power cable are optional, as direct soldering of wires to PCB connecting pads is an alternative method. High-temperature thick wall silicone rubber tubing serves as a replacement for traditional springs, with a recommended McMaster part number in the BOM.
