The Prusa did the worst overhang-wise, which I found surprising. The results are mixed, they all did pretty well but it seems like the Ultimaker did best with two out of four closest diameters. One thing to keep in mind is that you have to confirm the printing temperature when you start a new print, otherwise it doesn’t start heating up. The printer itself is very easy to work with though: you move through the menu with the knob just like most other printers, and it has a nice & clear interface. After a couple of tries, we decided to leave it out of our comparison, since the results wouldn’t be fair to compare because it’s sliced and printed in a different angle. The nozzle may have to be slightly calibrated, but we were very surprised to see the deformation of the bottom of the print. We didn’t manage to get a full print out after 6 tries. The INFI-20 really didn’t want to work with us. However, when I calibrated the bed again and printed something on the Ender covering the entire bed to see if it had an issue, it printed very regularly on the entire bed, so it seems to me that there is nothing wrong. I haven’t really had issues with it in the past so it seems like a new issue. In the end we just calibrated it the best we could, printed it and it went pretty okay. We swapped out the stock bed for a Prusa metal bed, but the issue persisted. The Ender had some issues: Pieter found out that the bed we were printing on wasn’t flat but rather convex. Printing the overhang looks more stable than printing the overhang on the Prusa. ![]() There are only two knobs, so if you have a problem in the back of the bed, there isn’t really a way to fix that easily.Īlso, the printer breaks the fourth wall when walking you through the calibration steps: ![]() You have to wiggle a paper between the nozzle and the bed, and move the bed with the knobs in the front manually. The calibration process for the Ultimaker is a little annoying, and it doesn’t feel very accurate. The nozzle was printing too far from the bed initially. The Ultimaker did pretty well after we calibrated the Z axis. We also noticed that when printing the overhang, the print bounces around a little. The Prusa did have some old filament stuck to the hot end, which stuck to the print at some point. It was a matter of loading filament and file, and go. The Prusa and the Ultimaker gave us the best and fastest results. We are also comparing workflow and ease of use.
