QuoteRalf I did some testing last year, but I haven't had the time to move on with a more systematic test. It was fun to build the rig, but very time consuming to actually do some tests. I have mostly done tests with ABS, which just confirms that higher temp=higher strength, within reason of course. Nice setup. Nice to see someone like-minded. Hiw much did your setup cost?by strantor - General
Quoteaduy Quotestrantor Quoteaduy Ive found that getting proper adhesion is fairly consistent amongst different materials, for example all thermoplastics perform better when they are dried before printing, except for pla using a heated build chamber always helps with adhesion.

Quotejamesdanielv strantor : I just viewed it, here is a video with an analog Gage. those analog gages tell a lot to people. Yes, as I mentioned in the video I also tried with an analog scale, and the recoil stripped the gears in the scale once the part broke. I considered purchasing this big game scale, but decided against it, as on top of the fact that it might also break, the scale worby strantor - General

Quotejamesdanielv I always used tensile strength to compare plastics performance. not that it is perfect, and it really does not tell me much. this tells me that bonding strength is different for each plastic. now I'm curious as to why, is it temp difference or something else. I actually found this data very useful. graphs are nice, but seeing video of some sort of Gage or measurement devicby strantor - General
QuoteSrek Thanks for the info, i were actually looking for something like this. PET (like T-Glase) might really be interesting to you, it is lightweight and seriously strong while much easier to print than nylon and less warp prone than ABS. Yes, I have T-glase in the mail headed my way as speak. It is what I am waiting for before posting my test results.by strantor - General
Quotejzatopa If you are going to continue doing testing on your own you will really need to make sure you track everything. Some of the main factors are design, print material type, print material brand, temp controlled environment (oven), acetone treatment, print temp and infill. Could you add that information to the data you are sharing? Sure thing. I will create a new thread for this purby strantor - General
Hello RepRap forum, this is my first post. I'm relatively new to 3D printing. I got a 3D printer for one reason: to build a prosthetic hand for my father. For this, I need strong (in all 3 axes), durable prints. You could say that getting super strong prints is all I care about, and I'm feeling almost all alone in that. Since entering the world of 3D printing, I find an overwhelming amount of inby strantor - General
