Printrbot sells a few different 3D printers, the smallest of which is the Printrbot Jr. This desktop 3D printer is light, it’s compact and it uses only non-toxic, biodegradable materials. However, what that means is it cannot use ABS plastic, only PLA filament.
The Printrbot Jr. has one print mode and can print up to 70 millimeters per second, which is about mid-range compared to other devices. Its max build volume is 99 cubic inches, with a max build depth of 4 inches, a build length of 5.5 inches and a build height of 4.5 inches. Its minimum print layer thickness is 0.4 millimeters.
This printer only uses PLA (polylactic acid) filament. We prefer 3D printers that also use ABS (acrylonitrile butadiene styrene).
This home 3D printer is not itsy or bitsy, but when compared with other desktop 3D printers, it is definitely small enough to have earned its “junior” title. The printer is 600 cubic inches – 10 inches long by 6 inches wide by 10 inches high – and weighs only 11 pounds. Due to its size, this home 3D printer is easily portable, which is ideal when moving between work stations.
Although the smaller size is great for compact spaces, there are a few design elements missing, including a heated platform, which is disappointing.
The Printrbot Jr. 3D printer includes a power supply and printing software, which is a plus, but it is missing a USB cable, which isn’t a deal breaker, but it would have been nice for it to be included with the purchase.
Connectivity for this 3D printer is a bit of a letdown, as you can only connect using a USB cord, which you have to buy separately. We really wish the 3D printer had Wi-Fi connectivity capabilities, or even just a slot to slide in your SD card.
Printrbot does not provide a warranty for the Jr., which is disconcerting.
If you plan to purchase the home 3D printer assembled, but still run into technical difficulties, you can email support. If you choose to build the kit yourself, you can watch a six-video series on YouTube. The step-by-step picture guide on Printrbot's website is much easier to follow, however.
The Printrbot Jr. 3D printer is small of size and unfortunately, small on charm. We are missing several features in this version, including a heating pad, a USB cable, more connectivity options and telephone support. Although, we do appreciate how portable the printer is.
Small and lightweight, this 3D printer can go wherever you need it to go.
A heated platform is not included with this 3D printer.
The Printrbot Jr. is a good option for making small objects, and with its wood frame, it is extremely light.
