MojoKid writes: 3D Printing start-up Ultimaker announced its second generation printer, the Ultimaker 2. The new printer features significant redesigns from the first iteration of the Ultimaker. The company says that the new machine is more accurate, more efficient, and it’s even quieter at 49dB. Specifically, the Ultimaker 2 has a new CNC-milled case (that’s all white with glowing sidewalls) with an OLED display, and its glass and aluminum build platform is designed to cool quickly so you can peel completed projects off more easily. The Ultimaker 2 can print with multiple materials, including PLA, ABS, and PVA, and is WiFi-compatible so you can print from a mobile device or computer. Ultimaker is also launching its Cura open source software, which the company claims can pre-process 3D files some 60 times faster than other open source applications and makes it easy to load and work with 3D files.
