TPU
TPU is lovely stuff. It doesn’t do well in Bambu Labs AMS. It is bendy like cooked spaghetti and does not do well when you try to push it.
TPU absorbs water quickly and it absorbs a lot. If you take it and print it will not look its best. You need to dry it before you use it. If the print takes a long time you can see a difference between the start and end of a print. If you are printing a large thing you might have to print from a dry box to have the whole thing come out OK.
