I am planning on getting a 3D printer soon and I was just wondering, what do you do with 3D prints that either failed or were prototypes that you no longer want? I tried looking online but the closest I got was effects on environment, turning prints…

Can I mix ABS and PLA when recycling filament?

I'm thinking of recycling some filament from a couple of recently failed prints. I can reuse them in the future for basic prototypes, so I'm not concerned with whatever weird mixture of colors come out (they are of a few different colors). The thing…

Uses for PLA scraps

I recently got a 3D printer and have been experimenting with it a lot, resulting in a lot of failed prints (as well as successes, fortunately). I'd like to, if possible, find a way to reuse the material from these failed prints. I am thinking about…

Using the end of a spool

I've seen several Q&As on recycling and reusing plastic from failed prints, but what have you done with the last few meters of filament? I've been keeping the ends of PLA (or sections I needed to cut) to maybe use for friction welding pieces…

Optimal ratio of fresh to used nylon powder

I am operating a laser sintering machine, using polyamide 2200 powder (with a grain size of approximately 50 micrometers). During a print, a lot of powder goes unsintered and can theoretically be reused. However, using purely recycled powder…

Is there a machine (for hobbyists) that will make filament based on the type of plastic I put in. I will sort the plastic before I will put it in the machine. I have seen the filabot but this uses only plastic from previous prints not plastic types…

Every time I try melting a scrap piece of plastic it ends up turning brown, smelling, and smoking before even melting down completely. My entire home ends up filled with cancerous fumes and there's no way I'm baking any food in my oven ever again.…

Cleaning IPA with the help of Mercury wash-and-cure?

I have seen that you can clean used IPA from resin by putting it in the sun a while, making the resin dissolved in the IPA cure. Could I do the same thing just using the cure-mode in with the Elegoo Mercury wash-and-cure-station?
