Anyone doing any projects in 3D-printed plastic?

[ibj40]

I got some pieces through Shapeways which are printed in what they describe as White Natural Versatile Plastic.

I need to fill a couple of features on one of the pieces, and wondering what to use.

I work primarily in diecast and plastic, so if I have the same issues with those materials, depending on the size of what I am trying to repair, I use either JB Weld or Bondo.

Anyone got any tricks up their sleeve?

Thanks!

I recently 3D printed this '61 Volvo P1800, and due to the printer size, I had to cut the file and print it in halves. I joined them back together with superglue, and the filled the rest in with Dynatron Putty-Cote which is a two part body putty much like Bondo.

No issues, everything feather-edged out nicely, but more than likely when this becomes a full WIP and painting time arrives, I'll put a coat of BIN-Zinnser under the primer to ward off any paint surprises with the body putty/resin combo.

Did you put anything under the roof to reinforce the seam?

 

Thanks!

I superglued a strip of styrene from side to side on one half of the body, and then superglued the halves together. Eventually, I'll get a second bigger printer, but after spending upwards of SEVEN HUNDRED DOLLARS for a full tank of oil for the house the other day, that's going to be quite a while now. ?

That white plastic that Shapeways uses is pure garbage. I got an 1/8 scale 32 Ford grill. I tried to sand it and it just won't sand. The plastic is more like a nylon, no glue sticks to it.

I nw have my own resin printer and don't buy from Shapeways.

Shapeways keeps changing the names of their materials, but I do believe that "White Natural Versatile Plastic" is in fact Nylon.  The prints are very porous and paint/glues will not adhere very well to Nylon.

More workable are resins like "Ultra Detail" and "Extreme Detail" (used to be called FUD and FXD).

Bill, your Volvo P1800 coupe.

Are you planning to build the Saint's car from the TV series that the late Roger Moore starred in?

Those nylon parts are very porous indeed. But you can improve the material properties and paint adhesion by filling the pores with CA glue. It will absorb a lot..

CA will work as a filler but large quantities can be nasty to breathe. Be sure you’re well ventilated. Another application available by Smooth-On is XTC-3D, specifically made for that purpose.

I use CA glue ( like zapagap) and have been using Shapeways items for years now without an issue. I  use cardboard nail files from the dollar store to sand also.....

No, not exactly. I think his car was a '63 in white. Mine may be a '63 (front gullwing bumpers), but I'd like to do another color besides white.
