Just noticed a new consumer level FDM machine that uses linear motors for the X-Y axis instead of the usual steppers and belts. Full closed loop positioning. Wonder if that's going to be a trend in consumer machines. By "linear motor" I mean it's a magnetic rail, like a railgun, https://peopoly.net/products/magneto-x

Well, Ultem has a Tg & HDT of only ~350F.
The collector can get hotter than that.
For this application- it just needed to hold up long enough to get me quietly down the road about 10 miles.
That's just what I needed it to do.
It was tossed in the trash afterward- as it was no longer required.

It would also have been super easy to make the same part in 6061 on a milling machine- if it was required to be a more permanent solution.

If the need were such that I were to consider 3D Printing another one of those for a longer term application- I'd use my newly developed SLS HT-25 material- that stuff will take almost 600F.
