Dimensions and details for Ultimaker Heated Bed for use with Ultimaker 2

Posted · Dimensions and details for Ultimaker Heated Bed for use with Ultimaker 2

I'm looking to purchase a heated bed to upgrade an existing printer, and currently the Ultimaker Heated Bed for use with Ultimaker 2 is near the top of my list.  However, to decide if it is acceptable, I need some details about it that I haven't found online.


  1. First off, is it capable of reaching 125 c, or is it limited to 100 c?  Obviously this depends on cooling conditions: in this case the unit will be in an enclosed printer, with no significant airflow.
  2. If I have the heater board does it accept direct analogue electrical input (say if I have a variable V-I power source), and does it provide analogue thermocouple output, or do I need a motherboard/controller to interface with it safely?  The connector looks like it's just a simple input port, but I just want to be sure there's no chip I'm going to fry if I try to wire it up to our analogue power supplies.
  3. What are the board's external dimensions (L, W, t), preferably in cm or mm.
  4. Are there any raised features on the underside: mounting brackets, bumps, anything like that?  Is the bottom face flat and parallel with the top face?
  5. Is it recommended that I clip an aluminum or glass plate to the top face of this unit for good thermal uniformity and flatness?  If so are there standard clips, or is everyone just using those pinch binder clips?


Sorry for all the odd questions, this is outside my normal area: I'm a printing materials specialist, not an equipment specialist.  But it's gotta get done, so ¯\_(ツ)_/¯
