Ultimaker 3 - build plate

Recommended Posts

Hi all, 


I have two questions regarding Ultimaker 3.

First of all could you explain the function of the build plate heating in detail?

As you can see in the picture, which plate is going to be heated?


Second one: For some tests I want to build a tentering frame on the build plate. More precisely between the glas and metal plate. For this I what weight ist the maximum load for the printing bed? Especially no discrepancies in x- / y- / z-axis should occur. I couldn`t find any details in the manual.


Many thanks for your support.

Hi Barbara - welcome on board!


Regarding your first question, the heating element is underneath the aluminum plate below the glass. So when the bed is heated up the heating element heats up the aluminum plate which then heats up the glass.


For the second question, I don't understand what you mean or what you want to build. But regarding weight, I have not seen any numbers or recommendations yet about how much weight can be put on the build plate, but I would not go much higher than the weight of the usual models. Some users pause their print and put some weight (sand) inside the model, so a little bit more is possible, but you should avoid that the bed is hanging lower in the front than in the back due too much weight.

Hi Smithy, 


many thanks for your support. 

My plan is printing on textiles. Due to high elasticity of textiles I thought about building a tentering frame, that should be placed at building plate. Could you suggest an approximate weight for the maximum load? Or what's your experience on the weight of usual models?

Ok, now I think I understood what you mean (In German: Du meinst einen Spannrahmen?)

But why would you like to put the tentering frame between aluminum and glass plate? I am just interested...


Regarding weight, I have no idea, but 0.5 - 1kg should be no problem, maybe even more. There are some metal fill filaments and they are also heavier than normal material and this is also no problem. Is your frame so heavy?


And printing on textile sounds interesting, please post some results and describe which technique and settings you have used.

Not sure how you are going about it but most people that print on textiles will print the first layer or 2 of the print and then stop the print and place the textiles over the top and just tape it down and restart the print.


I think you should be more worried when adding anything between the platform and the glass about the glass then hitting the print heads due to it being higher, also about the loss of heat transfer between the platform and glass. 


Not 100% sure what you plan to print but i feel you might be over thinking the set up when just good old tape or bulldog clips might just do the trick just fine.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
