Hi folks, I just started with 3D printing and since I managed to do a couple of cool prints I am looking for advice on how to finish/polish the models. I couldn’t find any thread which pertains to making prints of different materials look great so I thought it would be worthwhile to create a thread to collect different ideas and techniques for various materials. I bet that the treatments will vary wildly with the material used.
I know that some people use their 3D printer just for rapid prototyping so they might not really be interested in making the end product look good, but I hope that there are enough folks here who want to make gifts and decorative objects for their home to engage in this discussion.
Example: I just started printing with HIPS and while I believe that I am in a good range in terms of print quality (future me will probably laugh about that statement ), I am looking for advice on how I can treat the surface of my model to get a great finish. Should I buy a Dremel with a couple of bits or should I buy sand paper? What grit size do you recommend? What about steel wool? Any experience with coatings? Are there paints and coatings I should stay away from because they can damage my model?
