I purchased a XYZ Davinci Jr 1.0 about two years ago. It has been sitting on the shelf most of the time. I let a friend borrow it for a few months and he returned it to me about 3 weeks ago. It has been running nearly nonstop ever since.
This printer can be had for $200 on Amazon. It definitely has its pros and cons but for a plug and play 3D printer I can not complain. I have only had one issue with it and that was the printer head clogged during a print. Since I cleaned it, it has not given me any further issues. I assume this could happen with ANY 3D printer and not just this one.
Before I purchased this unit, I had never touched a 3D printer. Until I let my friend borrow it, I might have only printed four things on it that had been downloaded from Grab-Cad. While finishing my Mechanical Design CADD Degree, I needed to go that extra step so I decided to use it for my presentation in the class and 3D print the ice cream scoop that I was assigned to draw in F360. This was my very first print designed by myself and it turned out perfectly and gave me a functional prototype for demo purposes for my presentation. (When I say Functional, I just mean it moves as the real one does, I would not try it on ice cream though.). I was very pleased with how it turned out and so were the instructors and other students.
During the process of printing the ice cream scoop, I found that the Green Masking Tape aka FrogTape works much better than the blue masking tape. (I have not tried any other methods as of yet other than the blue tape.) With the FrogTape, I can usually get multiple prints on the tape before having to replace it. So I am happy with the results of the FrogTape. I felt as if I was going to crack the glass bed when trying to remove the pieces with blue tape but this issue went away when I switched.
Currently I am printing my longest print. I will be sharing it here on the forum as soon as it is finished and I have been able to test it. I designed a custom dust shoe for the 611. The rough draft print came out well but the tolerances Just were not there and I broke a few layers. This did not surprise me much bc I had used the absolute roughest and fastest setting on the printer. (I am still tinkering and learning the capabilities of the machine so this first print was just an experiment to test for concept) That print took 8 hours. Since the proof of concept turned out well, I reconfigured the setting and the printer is halfway through my second attempt at the highest resolution at the slowest speed. This second model is turning out Much Nicer! All in all it looks like the print will take approximately 48hrs to fully print the shoe. But the detail is much higher and the body seems much sturdier since I raised the infill from 10% to 50%. The layers are also 0.1mm thick as opposed to 0.4 mm thick.
I am very pleased with how my design is coming out and can’t wait to test it to see how well it actually works on the 611. I will share more when I get further along with the project.
3D printing is great and it now looks like I have a new addiction. Lol.
The printer that I have is a great beginner printer for someone with no experience with 3D printers. Especially since it is Sooo easy to set up. This printer does have it shortcomings though. So an experienced individual will probably shy away from it. But if your new to the game and want a plug and play to print a few things or to just get your feet wet, then this might be a good candidate for you. It is not top of the line by any means but I feel as if I am getting my $$$$ our of it for the time being. I will most likely be adding another printer in the future for multiple reasons but will keep this one up and running also.
I wish you luck with your endeavors. I know that I am enjoying my 3D printer and hope that you enjoy yours just as much, if not more.
I am anxious to share my new dust shoe and will do so soon. And if anyone wants access to my STL file, I will be more than happy to share it with the community.
