    Makerbot Replicator 2 Review

    MakerBot Replicator 2 is a beautifully designed desktop 3d printer, which also makes it one of the more expensive 3d printers compared with others. The Makerbot Replicator 2 uses a PLA filament which is a renewable bioplastic that sticks to the platform reliably with practically no peeling, curling, sliding or shrinking.

    The Good:

    • Beautiful looking Steel chassis
    • LCD screen makes printing a little easier
    • Prints fast

    The Bad:

    • Expensive
    • No Starter filament
    • Not user-friendly

    Technical Specifications:

    • Print Technology: Fused Deposition Modeling
    • Build Volume: 28.5 L x 15.3 W x 15.5 H cm (11.2 x 6 x 6.1 in)
    • Layer Resolution: 100 Microns
    • Positioning precision: xy: 11 microns, z: 2.5 microns
    • Filament Diameter: 1.75 mm
    • Nozzle Diameter: 0.4 mm
    • Chasis: Powder coated steel
    • Body: PVC panels
    • Build Platform: Acrylic
    • XYZ Bearrings: wear-resistant, oil-infused bronze
    • Stepper Motors: 1.8 degree step angle with 1/16 microns stepping
    • Product Dimensions:
    • without spool: 49 L x 32 W x 38 H (cm) (19.1 x 16.5 x 14.7 in)
    • With Spool: 49 L x 42 W x 38 H cm ( 23 x 21.5 x 17 in)
    • Weight: 25.4 lbs (with packaging 37 lbs)
    • Software:
    • Makerbot Makerware
    • File type: STL, OBJ, THING
    • Operating system: windows 7+, Mac OS X (10.6+), Linux (Ubuntu 12.04+)

    Printrbot 3D Printer 2

    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.

    The Printrbot Simple 2014 fully assembled 3D printer has an open platform with an aluminum print bed and a frame constructed of machined aluminum and laser-cut birch wood for fabricating objects to maximum dimensions of 4 x 4 x 4 inches/100 x 100 x 100 mm (H x W x D) using PLA (polylactic acid) thermoplastic filament. The printer has a vertical resolution of 100 microns (0.10 mm) and comes with a direct drive 6061 aluminum extruder with a shrouded cooling fan, and an Ubis hot end that accepts 1.75 mm PLA filament.

    The unheated 6061 aluminum print bed has a matte finish and provides a level build surface that will not warp. The printer is commanded through the provided micro USB cable using G-code numerical control instructions. An SD memory card slot can store G-code instructions on a memory card (sold separately) for operation without a connection to a computer. It can be used with 3D printer management software packages (sold separately). The frame is made of laser-cut birch wood. Machined aluminum axis rods with linear bearings and injection molded gears help ensure precise movement. The size 17 stepper motors meet the National Electrical Manufacturers Association (NEMA) standard ICS 16-2001. The printer comes with a sample spool of PLA filament.
