Description
Graphite heatbed for Creality K1 series printers by R3Men (part of Devil Design Team)
Note: This is advance upgrade, it require wiring up AC, before powering on please ensure product/wiring has been checked or installed by a license electrician. Please ensure you wire ground wiring to the cast bed, we recommend a external thermal fuse(125c-135c) for added safety.
Note: Order after 4th May 2025 (K1 Max has AC/Magnet Pre-Assembled, this have resulted in increase in price to account assembly cost), Future K1 will be pre-assembled once previous batch are sold through. Order after 11 August 2025, will include SSR for both K1 Max/K1 version.

Specification:
- Ultra-flat: within 0.1mm flatness
- Edge to Edge AC Heater
- No warping: bed stays super flat at 115C as well as at 60C. No need to heat soak the bed for long time like aluminum beds.
- It is over 30% lighter than aluminum and heats faster. Huge improvement for K1/K1C/K1SE after upgrading to AC heater you shorten the heat to 100C time from around 5 minutes down to less than 2 minutes.
- Works with Eddy current sensors (Cartographer, Beacon, BTT Eddy). Magnetic sheet and build plate are enough for eddy current sensor to work properly.
Note: Suitable for both 110V or 220V, for International customer, please contact us for documentation or check original R3Men documentation as wiring will depending on your local country or power AC you using your machine on. We will only note documentation for 220v.
Graphite thermal expansion
- Graphite is unique due to its thermal expansion properties (CTE). Typically, when a material or substance is heated, it expands. However, graphite has a remarkably low coefficient of thermal expansion.
- Graphite thermal expansion coefficient is −1.4 × 10−6/°C to 1.1 × 10−6/°C from room temperature to 1350 °C
PTFE coating
- PTFE thermal expansion coefficient is about 150 times higher than graphite. It is 151 x 10-6 per °C. It is even over 10 times higher than steel.
- Coating graphite in PTFE may result in coating separation after heating cycles due to huge difference in CTE.
- Our graphite beds are high purity graphite and they are not coated. They were tested for months in hundreds of heating cycles and showed no issues.
Part/Tools that Not Included, which you will need (For K1 / K1C / K1 SE)
Part/Tools that Not Included, which you will need (For K1 Max)
IMPORTANT:
- If you wipe the graphite plate with alcohol or any liquid make sure that it is completely dry before gluing the heater and magnet!!! Graphite has pores and liquid will be trapped inside it and will make the glue bubble when heated. Please ensure you let the adhesive cure at least 24 hours with even pressure is applied on build plate/heater/magnet during the cure time .
- I suggest gluing the magnet on a 100C hot bed (the last step of installation) to make sure the graphite is dry and it glues flat. This was tested couple time and worked great. [Please take care, we recommended using heat resistant gloves when performing this step]
Shipping Note:
We ship items in a flat cardboard sandwich box to prevent warping during transit. This item cannot be combined with non-flat items for shipping, so please expect additional freight costs when bundling it with smaller parts or filament. If we can bundle smaller items within the same box, we will update the shipping total before processing your payment. Otherwise, feel free to contact support for a customised quote.
General Note: You should never cut into AC heater pad.
Preparation:
Before applying either the magnetic sheet(for steel flex plate) or silicone heater to the bottom side we recommend to scuff surface with steel wool and wipe clean with isopropyl alcohol (IPA) before application. For Graphite, ensure the surface is completely dried before applying anything onto build plate such as AC Pad or Magnet.

Note
- To make sure the optimum performance for this heater is achievable, both temperature sensing and control elements should installed to controller.
Caution
- The Heater Mat is not suitable for stand-alone operation.
- Do not cut into the heater pad
- Ensure proper strain relief on wiring and proper grounding of the cast bed.
Warning
- These heaters shall only be used where adequate electrical, thermal and mechanical barriers are provided to prevent access to hazardous parts without the use of a tool.
Estimate shipping
Deliveries within Australia
For shipping prices, please use the above estimated shipping costs. Shipping costs depend on your location, order size, and desired courier service and provider. Orders are dispatched within the same or by next business day for in-stock products from local Brisbane Queensland warehouse depending on courier.
