Aluminum Heated Build Plate for 3D Printer

thingiverse

Aluminum Heated Build Plate It was designed to be used as heated build surface of typical 3d printer with 200 x 200 mm XY build area. Plate is compatible with MK2, MK2A and MK2B heat bed PCBs. Material is 4mm thick T6061-T6 aluminum alloy. Plate has sufficient thickness to prevent twists and to maintain high flatness across whole building area. Thing uses countersunk mounting screws to eliminate possibility of hot end to run into a screw and damage itself. Another convenient feature is the milled channel for thermistor installation on the bottom of the plate. This feature makes assembly easy and clean, thermistor wiring is hidden in between plate and heated bed PCB. Anodized aluminum plate kits for purchase:http://reprapchampion.com/build-plate-short-kithttp://reprapchampion.com/build-plate-full-kithttp://www.ebay.com/itm/321336349749 Plate design features: Thick 4mm plate maintains flatness across whole area. Scratch resistant anodized surface. Hidden countersunk mounting screws. Kit uses high temperature resistant silicone rubber spacers instead of typical springs. Thermistor is hidden in the milled channel on the bottom of the plate. Instructions If you wish to build this plate yourself: Consult with drawings and supplied BOM. Great source of raw materials is onlinemetals.com go there and buy 12" x 12" x 1/8" 6061-T6 aluminum alloy sheet. 1/8" material is thinner than 4mm, but still can be used with success. Cutting thick aluminum without CNC mill or router could be hard. Assuming builder has an access to CNC router and CAM software - supplied STL or STEP file can be used to generate G-code. 1/8" 2-flute endmill at high rpm could do cutting job on aluminum plate. Source for all hardware is mcmaster.com. See BOM for part numbers. Connecting bridge for MK2B is not really necessary, if you build plate yourself. M2 mounting hardware for connecting power cable can be omitted too - soldering the wires directly to PCB connecting pads would work. High temperature thick wall silicone rubber tubing is great to make spacers and replace old fashion springs. See BOM for mcmaster part number.
