I have a really hard time finding a D-Limolene supplier in Europe (D-Limolene is a solvent that dissolves HIPS plastic used as 3D printing material ) so my next best option is ABS . I want to print a mold core and after lamination to dissolve it , if i print in ABS i have to use acetone to dissolve it . I  must soak my core in acetone for an hour max , would this be enough to ruin my part ? I dipped a small part i made in acetone for couple of hours and i notice some small softening of the surface part but nothing major ,as far as i can see. Since i want my part to take loads i don't feel really comfortable using acetone . What is your view on this?
