PLA objects can be fabricated by 3D printing, casting, injection moulding, extrusion, machining, and solvent welding. PLA filament for use in 3D printing. PLA is used as a feedstock material in desktop fused filament fabrication by 3D printers, such as RepRap printers. [39] [40] PLA can be solvent welded using dichloromethane. [41]
MakerBot Replicator 2 Desktop 3D Printer. In September 2012, MakerBot introduced the Replicator 2. This newest model again increased the build volume, this time to 28.5 cm × 15.3 cm × 15.5 cm (11.2 in × 6.0 in × 6.1 in, L×W×H) and can print at 100 μm per layer. The dual extruder was changed back to a single extruder head, while the ...
3D printing filament is the thermoplastic feedstock for fused deposition modeling 3D printers. There are many types of filament available with different properties. [1] Filament comes in a range of diameters, most commonly 1.75 mm and 2.85 mm, [2] with the latter often being confused with the less common 3 mm. [3]
In addition, several RecycleBots have been designed and fabricated to convert waste plastic, such as shampoo containers and milk jugs, into inexpensive RepRap filament. [18] There is some evidence that using this approach of distributed recycling is better for the environment [19] [20] [21] and can be useful for creating "fair trade filament". [22]
OpenSCAD is a free and open source software that uses scripting to design 3D objects. [16] Many 3D printers can be upgraded with 3D-printed parts. Thingiverse users produce many improvements and modifications for a variety of platforms. Popular examples of community-based 3D printer projects include the RepRap project and the Contraptor project ...
Josef Průša was a core developer of the RepRap project who had previously developed a PCB heated "print bed". He adapted and simplified the RepRap Mendel design, reducing the time to print 3D plastic parts from 20 to 10 hours, changing to the use of two Z-axis motors to simplify the frame, and including 3D printed bushings in place of regular bearings.
