This project aimed to give the Athena Delta printer a sleek looking heated bed that took advantage of the printer's shape. Previous heated bed set-ups for this printer use square beds. This shape does not take advantage of the total printable area of the delta style printer. Unfortunately, the only round heated bed I was able to find that matched the size requirement was a 24V system. Although this solution requires the use of an additional 24V power supply, it keeps the high amperage draw from the bed separate from you expensive Melzi board.

Abstract

This project aimed to give the Athena Delta printer a sleek looking heated bed that took advantage of the printer's shape. Previous heated bed set-ups for this printer use square beds. This shape does not take advantage of the total printable area of the delta style printer. Unfortunately, the only round heated bed I was able to find that matched the size requirement was a 24V system. Although this solution requires the use of an additional 24V power supply, it keeps the high amperage draw from the bed separate from you expensive Melzi board.

Bill of Materials

All prices do not include shipping or sales tax. Most Amazon Parts are Amazon prime elegable, which is why I went with those specific parts. You may be able to find them cheaper elsewhere.

This project is still a work in progress, as my current wiring is a mess. Additional panel mount connectors will be added in in the coming weeks to provide a sleek finished product.
