Printrbot Simple Metal Heatbed Mod

I've moved over to YouMagine.com All updates on this design can be found here: https://www.youmagine.com/designs/edit-thing-printrbot-simple-metal-heatbed Thanks.

Designed with a heated platform that matches the maximum build platform and is thermally insulated from the rest of the bot. You can easily reach a max temp of 115- 120C in a few minutes with this design for optimal large part ABS prints.

The stock Printrbot Metal Simple is a fantastic little printer with an exceptional degree of accuracy for its price, I really wouldn't change a thing about it. Recently I had to print a few large flat designs and wanted to try attaching a heat bed to get them perfectly flat.

Print four of these brackets and attach the 6X6 aluminum print bed heatbed and thermistor from http://printrbot.com/ BOM and other details in the instructions.

The ideology of mounting the heat bed on a raised platform design posted here is that you are able to insulate the moving parts from heat, use less power and reach a higher maximum temperature. Your Printrbot Simple Metal can print PLA super flat, and experiment other filaments like ABS and Nylon. If you plan to print with high temperature filaments, I recommend printing these parts in ABS for long term durability.

• WARNING - You must replace the laptop style power source and add your own 12 volt power source with enough amps to run the heated print surface. An ATX power supply that you would find in an old PC tower is a really good option. More details in the instructions.
