I have been working with Mamorubot for some time now. They make excellent high quality filament, really nice build surfaces, and were also selling 3D printers. Their printers generally had a uniqueness to them that many other printers on the market lacked. They had 400x400x500 coreXY 3D printer, and a 200x200x200 h-bot that used an amazing sturdy steel frame with linear rails. Once I saw they were releasing a DLP printer I was pretty excited. Now Mamorubot doesn’t sell their printers direct anymore and they are sold through other companies, one of which is called Hieha. This review is for the Mamorubot UVee/Hieha UV DLP 3D Printer

Unboxing and First Impressions

I received a small, well packaged printer box a bit bigger then the printer itself. There was something that sounded broken from shipping when I was carrying it into the studio. Upon opening to box I could see that they used an appropriate amount of protective styrofoam however there was a mount inside the electronics area that had broken for one of the components. I mentioned this to Mamorubot and they said there would be an improvement to avoid that.

I removed the printer and accessories from the box and checked the inventory. It arrived with a USB and a scraper and my particular test unit had been used at the factory. There was noticeably no resin which was due to shipping limitations.

The build size is a very typical for a DLP printer at 115mm x 65mm x 155mm and it uses a 2K LCD screen. It uses 405nm UV resin and it comes with a 3.5 inch touchscreen with a very simple and clean interface. It uses a white steel fold up cover with darkened window which has a nice aethestic to it from my perspective.The UVee accepts prints from a USB drive into a USB port is located in the right side of the printer. It is more convenient then others DLP printers I’ve used with a USB port located on the rear of the printer. I also noticed the rail for the z axis is different then I’ve seen other printers use. It’s an all metal linear guide that appears to do its job as required.

Assembly & First Prints

I use the word assembly very loosely here as there is not much to assemble in all honesty. You need to make sure the vat is tightened down with the two side screws, and that the build plate is tightened down onto the z axis assembly. I asked about build plate leveling, however Mamorubot said this is done at the factory. I wish the leveling was a more elegant solution than the 4 screws tightening down on the steel plates however it did the job.

The next step was slicing. I downloaded Chitubox to use as a slicer for this printer, and went ahead with setting up the slicer with the provided settings from the pdf on the provided USB drive. Slicing for resin printing is not like FDM printing. I recommend researching proper slicing methods for DLP 3D printing. I inserted the USB drive into the USB port on the right side of the machine and loaded a test print via the touchscreen, which was very responsive and worked well. I also liked the mini 3D preview image shown in the touchscreen. I poured some of the Monocure rapid grey resin in the vat about 1/4 up the side.

Mini Phil

The first print being a small Phil-a-ment came out great. I was happy with the 50um resolution and the quality. Using the yellow scraper that came with the kit popped the print off the build plate. I rinsed it in 99% isopropyl alcohol and water, followed by some time in my DIY LED curing chamber. After it was cured I noticed I should have washed the print a bit better before curing but in general it came out pretty good for a first print.

Printing and Maintenance

I moved onto some more prints and I did have a few failures with the Monocure Rapid grey. I inquired with Mamorubot and they sent me a link to try Elegoo resin which I hadn’t used before. It was priced very well a $19.99 CAD for 500ml and I ordered it on Amazon. The FEP sheet that was installed still had plenty of life left, but for the purposes of the review I wanted to swap out the FEP sheet with some replacement FEP I had in stock. I unscrewed all the screws on the base and removed the old sheet. I cleaned the vat up with isopropyl alcohol, added the replacement sheet, and tightened all the screws. I poured some Elegoo resin in 1/4 up the side wall of the vat and the next print came out great again, a little blue Marvin.

I printed a bunch of successful prints with the Elegoo blue resin, like the Captain America and the Night King busts shown above, and I did not have any of the issues I was experiencing with the previous prints. I sliced them, printed them, cleaned them, and cured them.

I proceeded to try Elegoo black resin as well. Using the exact same settings the print came out the same quality as the blue.

Conclusion

I have been really happy with the Mamorubot U-Vee. It is a simple machine that prints well with minimal fuss. The community is pretty small for this brand but the company is responsive from my experience and the community is growing. I like the simple look this printer has vs some of the other DLP/SLA printers out there. I wish the leveling of the build plate was more refined for future maintenance when leveling is required but that hasn’t caused any issues for me. Mamorubot delivers another competitively priced DLP printer to the market with the UVee that works.
