![]() To print the enclosure on Cetus, Richard puts together in F360. This positions the temperature controller, power supply, and MOSFET board all together. Thermocouple and wires are attached using a capton tape and finally the heated bed is remounted. A simple voltage divider is used to drop 24V down to 12V, the required temperature to turn on the MOSFET board. He then connects the MOSFET board to power supply and operates it using relay output of a temperature controller. And a bi-metal switch is placed with its input, for the heated bed to stay in safe temperature range even with full power. Resistors are wired up in 4S-2P configurations to ensure current draw from power supply is almost 4.2A for a 100W output. Thermal adhesive can be used for the purpose too. He starts by attaching the power resistors with the two part epoxy. The switching MOSFET and power supply are more than what is needed for application but are used in the project because they were readily available with him. He uses 8 * 2.74 Ohm 15W Power Resistors Omron S8JC-Z15024C 24V 6.5A PSU 100 Deg C Bi-metal Switch High temperature PTFE coated Wire Omron E5CC Temperature Controller High current Heated bed MOSFET break out board. He wanted to upgrade his 3D printer, so he took some inspiration from a Youtube video of Marco Reps, and rolled up a powerful heated bed. Richard, the initiator of the project is into Magnetic Materials Engineering, and has a great deal of interest in everything related to CNC (Computerized Numerical Control) . Additionally, the heated bed would provide extra power supply to the printer so that overload can be avoided and would give over-temperature protection beyond the usual monitoring. Temperature plays an important role in the printing process too hot or too cold temperature can lead to a mess. ![]() This DIY heated bed is designed to monitor and set up the print bed temperature. It assists in improving the print quality drastically by maintaining ideal conditions for the printer to function. – Fast shipping, fullfilled from local warehouse, easy to get spare parts and accessories.Heated bed is an added module to 3D printer, that ensures a controlled printing process. – Professional support team with quick response.
