Like many, I'm fed up with the common MK2B heated bed. It has about 1.2 Ω when wired in 12 V configuration and 4.8 when wired in 24 V configuration. Both times it outputs about 120 W of heat when driven by the appropriate voltage, resulting heatup times to print temperature of 10 to 20 minutes.
Heatup time can be reduced to 2 minutes by simply driving it with 24 V while wiring it in 12 V configuration, but well, this almost max out a seperate 500 W 24 V power supply I dedicated to driving the heated bed. Additional requirements for this setup are at least AWG 15 wire and a high current MOSFET or SSR.
The additional cost of a 500W 24 V power supply, high current SSR and heavy wire is not neglectable at all, since the can easily be half of a printers price tag. Also, bulky power supplys and wires do not contribute to the overall design and weight aspects of a 3D printer.
There are many benefits of a mains voltage heated bed: I will be driven directly from mains, skips the need for an expensive power supply and can be driven by a cheap low current SSR without heatsink. It's also cheap and provides a structural support for your printing plate, be it glass, tufnol/garolite or PEI - which silicone heater pads do not do.
Thus, a mains voltage heated bed must exist, and this project is dedicated to make it real. Additionally, this is also an attempt in making this the safest heated bed available. If you have concerns with the design, please share your ideas in the comments.

- EASE OF REMOVAL OF 3D PRINT FROM BUILD-PLATE: The flexibility of the FLEKS3D™ Build-Plate makes it super easy to remove prints. We chose a highly resistant thermoset (plastic). This is because it is far more flexible and holds its form better than spring steel or other metals. We found that it is important to be able to flex the plate a lot for the really hard prints to remove. From our experience, just having a little bit of flex isn't enough for the prints that are really stuck on the build-plate
- EASE OF REPETITIVE PRINTING BY HAVING SEVERAL EASILY REPLACED PLATES: The FLEKS3D™ kit comes with 2 plates. This makes it possible to interchange them for an uninterrupted 3D printing experience.
- ULTRAGRIP WITH THE PROPRIETARY TEXTURE: The FLEKS3D™ Build-plate features proprietary texture that makes tape and hairspray unnecessary.
- LESS DISRUPTIVE TO THE LEVELING OF BUILD-PLATE: Resetting the leveling of the build-plate after each print is tedious to say the least. This is not necessary with the easy removal set-up that the FLEX3D™ incorporates. This is because it comes with 2 easily removed plates that fit snug in the permanent frame.
- BEST PRICE: Let's face it you work hard for your money. We don’t want to have you break the bank. We have made a great effort to be able to offer the FLEKS3D™ Build-Plate System at the best possible price. This is so we can offer this to as many people as possible.
- HEATED BED: We have not done extensive testing with a heated bed. This is since our UltraGrip™ texture creates a very strong grip and a heated bed haven't been necessary to avoid warping. The FLEKS3D™ is made of a thermoform plastic with a melting point at 311 F or 155 °C. If a heated bed is used the temperature needs to be set bellow this.

FLEKS3d comes in 3 standard sizes to fit 95% of the printers. Small is 6" by 6", medium 8" by 8" and large is 10" by 10" inch. In metric units: Small 152mm by 153mm, Medium 204mm by 204mm and large 254mm by 254mm. For MakerBot, there are custom FLEKS3D™ plates. These are available for Replicator 2, Replicator 2X and Replicator (5th gen) |
