Product Description

The UP! Mini 3D desktop printer has an all-metal enclosure and fabricates objects using 1.75 mm ABS (acrylonitrile butadiene styrene) or PLA (polylactic acid) thermoplastic filament (sold separately), with a vertical resolution from 200 to 400 microns (0.20 to 0.40 mm). The printer can build objects to maximum dimensions of 4.75 x 4.75 x 4.75 inches/120 x 120 x 120 mm (H x W x D). The included printer management software runs on a Windows or Mac OS X computer, reads Standard Tessellation Language (STL) files generated by computer-aided design (CAD) software (sold separately) and commands the printer through the provided USB cable.

The enclosure guards against room drafts to help minimize temperature fluctuation, and helps reduce operational noise and odor. A build platform heats to 51.4 degrees C to help provide thermal stability. A perforated cell board is held to the platform by full-side mounting channels for a secure fabrication base. Solid metal guide rails and precision slide bearings help ensure precise movement. The belt-driven stepper motors meet the National Electrical Manufacturers Association (NEMA) standard ICS 16-2001.

*H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

3D printers fabricate physical objects directly from computer-aided-design (CAD) data sources. Objects created by additive manufacturing are built by dispensing successive thin layers of molten material onto a moving platform base from a robotic extruder nozzle. The material is most commonly a thermoplastic or HDPE (high-density polyethylene) filament.

PP3DP manufactures UP! brand portable 3D printers and accessories. The company, founded in 2010, is headquartered in Beijing, China.

First, a few things about me. I am an industrial designer and have been using 3d printers for over 5 years at my job. I have been watching the prices come down slowly on Filament based printers for personal use and finally found this one to be the best value in a preassembled unit. I have been pleased with the print quality and the software. I couldn't give the printer 5 stars because I am having an issue with the filament randomly not feeding during a print but I'm not worried about this because the support that I have received in the past has been great. A couple weeks after I got the printer and had already printed several objects, I found that I needed to move the printer to my house from work. I started my first print job at home and I went to check on the progress and the static spark from my fingers must have fried one of the computer components because the unit shut off suddenly. I was distraught but after logging into the x-object support help desk on their website and asking for help, they sent me out a new unit! I just put the old one in the replacement's shipping box and printed the shipping label they emailed me and dropped it off at the UPS store. The new one hasn't had the same problem with static electricity and I have been printing successfully ever since. I will be resolving the current issue soon and I will comment on this review once that it is fixed.

A note: 3d printers seem to always have some sort of glitch here and there because they are complex systems. We have a Stratasys Fortus 400mc at work which cost easily 100k and we have to have a maintenance contract on it to keep it running. The tech guys have to come out yearly and sometimes more because of how many things can go wrong with these units.

The quality of the print with the Up Mini is very good. One of the best things about it is that the start and stop point of each layer is not at the same place so you don't get a "stitch" line on round objects like you do with other printers. This is the fourth model of 3D printer I've used.

The slicing and op software made for it is good, but is limited in the settings you can change such as head temperature and bed temperature settings. But, it's very easy to use.

Now for the BIG problem, the print head:

I have 2 of these printers and have the same problem with both of them, so I believe it's a design weakness: The feed gear in the head isn't very robust and doesn't always feed the filament well. I've tried over 50 different rolls of filament and on both printers and have the same problem with both. Neither of my printers will feed PLA filament at all. It just makes a clicking sound and doesn't feed, so you can't get a print. For this reason only, I would not recommend the printer until they upgrade the print head feed gear mechanism. Now, one of my print heads won't feed ANYTHING, including filament made by the company. The head is under-designed and very weak. If it wasn't for the head, it would be a great printer. However, one of my printers is just a desk ornament and the company does a very poor job of support. I can't even BUY a replacement head. Maybe I'll design and build my own someday, but don't have the time right now.

I've got several Flashforge printers and they ALL work really well and I've never had a problem with feeding. So, for just a few dollars more, I'd get the Flashforge and you can feed ANY 1.75mm filament with it and get a bigger build plane.

While my primary reason for choosing this particular printer was a combination of quality and the enclosed and therefore, semi-environmentally protected print area, this little unit provides out of the box printing. Needless to say, I have been having a blast printing various items.

That being said, and why I deducted two stars.

-½ star due to the fact that there seems to be no way to center the print table. Mine, for some reason, is off center on the X-axis (prints too close to the front), which in turn results in larger models curling. To correct this, I have to manually move the heating table to center, during the table height calibration process. Once set, I have been able to print several models without a hitch.

- 1½ star due to their horrendous warranty setup. For example, I have been trying to register my product for the past week, and have been thus far, unsuccessful. On their site, it says you have to register within 7 days or your warranty will be voided. And yet they provide no means to register the product.

Update: I finally was able to find the correct person to contact. Since I purchased this item through Amazon, I had to register it through [...] (as opposed to pp3dp.com, which the box says). The up3dusa.com site actually has a registration link under the support tab. It also contains links to not only the 3d test print bunny but the manual, software, and windoze drivers. Still working on the x-axis alignment but that has not been a serious hindrance.

That said, I love love love this printer! While it did make top ten in the maker magazine, and even then was a bit far down their list, this printer is literally an out-of-the box setup.
