Ultem 9085

Recommended Posts

Well not as a standard but perhaps with a lot of effort it could perhaps be made to.

Challenges:

- i think Ultem requires a processing temp of around 350-360C and the UM2 is limited to 260C.

Possible solution: hw and sw modification is possible, I think Anders Olsson managed to go up to 350C with 3dsolex I2K washer (to prevent the PTFE coupler from softening) when using a modified fw to allow for higher temps.

- I think Ultem 9085 is only available in 1.75mm size from what I've seen.

Possible solution: modify extrusion train to accept 1.75mm, it can be done.

You might want to examine the Stratasys Fortus line of machines, many of them support the Ultem 9085 material.

I wonder if brass nozzles would work well or if any other nozzle material is needed?

Please go ahead and try, I am interested in the results :)

Another challenge :

Layer bonding or interdiffusion

Ultem Tg = 180° ---> T° of the building chamber = 195°

I think it will be difficult to reach this temperature only with the original heating bed and the steppers will not like it.

You have another follower ;)

    • Architect Design Contest | People
      The goal of this contest is to design a set of people figurines that could be used in such a project to make an area, office or mall seem populated. 
      Think of different types of people in different environments, like walking people, people standing still, working people, and both men and women.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
