I really love my Raise3D N2+ 12"x12"x24" They also make the N2 which is 12"x12"x12". You can get the printer with single or dual extruder.
Prints ABS, PLA, PC-blends, flexible, HIPS, etc. I think the only thing it won’t print is PEEK because the hot end doesn’t go up high enough.
For the times that the extruder gets clogged, it comes with a ram rod and it’s easy to get into the hot end. No having to take fans off. Just three short thumbscrews to remove the front plate and then insert the ram rod.
It’s a nice looking printer with extremely smooth and beautiful prints every time. My 0.2 layer height prints are cleaner than the prints from my Replicator 2x at 0.1 layer height. Touch screen control panel (running some version of Android software).
It runs 24/7 and has a great software interface. Manual placement or automatic support generation. You can even cut the part in the software.
we are 3D service Studio with heavy volume and as diverse audience as yours. We are doing a lot of workshops for students from K2 till high grades. We are working with Faculty and Inventors and had similar problem to find proper, easy to use, not complicated printers for our client open area.
we tested around 22 printers in the past 16 months and depends on desired size and work type we decided on Zortrax M200 and Up!Mini 2. For very large prints we are using Fusion3 F-400. Zortrax has simple but powerful ZSuite and we run 280 hrs. jobs on it, mainly unattended. Bed size around 200 mm square, Up!Mini is easy to use as well. Both are enclosed, Mini has Hepa filter. We had both printers operated by 6-7 graders or total 3D novices.
F400 is large 14 inches each (xyz axis) and needs 3D deeper knowledge.
Where is your library located?
If you are in Georgia, by any chance, please stop by in our Studio. I can also share with our tests results. Some of the tested printers we still have and using them from time to time. For place like yours, we will never recommend printers from “geeks” category ( nothing wrong with geeks, I’m one) as you have choice of running it like clockwork or spend time fixing printers
you can contact me at ssliw@usa.net if you would to have more infomation about our decisions process.
I woul recommend the N2 or N2+ from Raise3D. It’s a closed 3d printer how can reach 300 °c . It can work 100 hours without any check and the precision is really impressive.
