From raising $830,000 through Kickstarter to winning MAKE magazine awards, it’s clear Printrbot doesn't play around. Their printers are top tier and their assembly instructions are easy to understand. The Printrbot Jr. V2 features a super flat heated aluminum bed (flatness allows for consistency and heating makes for a more stable base), high precision ACME rods for silky smooth Z axis movement, and GT2 belts for durability and longevity of function. Additionally, it’s important to note that the included hot end (where the plastic comes out) is equipped to handle 1.75mm plastic filaments and nothing larger. That said, if you want to start printing things with higher volume and plastic density, it’s easy to swap the hot end for a 3mm compatible unit. All in, this is one of the best consumer grade 3D printer kits out there and because of the 3D printer poll, you can buy it at Massdrop price levels.
