Possible temperature range

[ChristofWH 1]

Hi,

we want to introduce a new 3D printer filament to market. Does Ultimaker 2 temperature range include a temperature of 150°C ? Are the settings customizable?

Greetings,

Christof

Interesting, what kind of material?

150c is ok.

You can set custom material profiles, just export the materials.txt file from the printer to SD card, change it in a text editor (f.e. notepad++) and add or change materials settings. Then import again from the SD card.

In the menu:

material / settings / export to SD

Thank you a lot for fast response. Our material will be based on pure PHA. PHA consists mainly of long fiber of PHBs. Our material will directly be produced in bacteria with the perfect properties for 3D printing. Since we are at a point where we want to test our filaments, we need a 3D printer.

Seems it will be an Ultimaker2. :-)

So what kind of use do you foresee for this material? What are the expected properties after printing? Not very heat resistant is presume

Something else, there is an lowest temp limmit build in the printer to prevent it from printing with a cold nozzle, not sure whats the default lowest temp (probably much lower than 150) , but as the UM2 is open source any setting can be changed easily.

And last, if you'r playing with "beta" filament it might be wise to get a "olsson block" (www.3dsolex.com) so you can easily clean nozzles and use larger sizes.

To prevent cold extrusions the minimum extrusion temperature is 170°C by default. That's a common Marlin feature and not special to Ultimaker.

The default of 170°C is set after power on and after leaving the "Move material" menu, but can be changed by executing a M302 gcode command.

In case of an Ultimaker2 one could even prepare an autostart gcode-file on the sdcard with this command.

As a conclusion: no need to fiddle with the firmware, just do it - we're curious!

Thank you all. Also for the olsson block. It seems we will need it.

Attached is a image with some properties of our filament. But i think we have to print it and to make a small video to show was it can do. :-) I will let you know.

We will play arround with PHA Phi1 and PHA Phi2

Umm a plastic that never hardens *o*. So flexible umm weird material. Can't wait to see that

I am also curious to see how it will be. But we need a few weeks. I will give you an update, asap. :-)
