    They bought the part & the seller told them it was ABS (melts at 90°~100°C), but it was PLA (~50°C). The og part was made from fiberglas (~80°C).

      Fiberglass resin is good far beyond 80C. With the right resin they can rate to 200C.

      Porsche used fiberglass resin in their lemans cars in the 70s.

      Gunna nerd out right quick.

      Even if the og part was fiberglass, it would have to be have a binder to hold it together(which is usually epoxy resin).

      But even then!

      ABS is still a temperature sensitive polymer, deposited in layers!

      The only 3d printing that could hold up reliably would be lithography via resin with a rising “bed” and extended curing (forgive me for not using the correct terminology, I’m an old school 5 axis CNC operator that’s still learning about the new stuff)

      Nothing that could fail catastrophically under stress should be used in the aeronautical industry.

        There are some crazy plastics you can 3d print (with high end printers) like PEEK. Most consumer grade printers can’t print those sorts of advanced materials that would be suitable. Most consumer resin prints are very brittle and not very suitable either.

        If you ordered it from a print shop with the right equipment and materials, FDM printing should be fine.

        Yes!
        The nerds in the linked comments nerded out about that too - with fibre materials construction matters (the weave if you won’t), it’s not just about the material.

          Hey! I’ve been thinking about a fiber reinforced plastic submarine used to send billionaires to go see the Titanic!

          We will be using an Atari joystick to control forward, reverse, left and right. The button is for dive (downwards)

          It’s going to be great!
