3D Printing
A 3d
printing is a computer aided manufacturing (CAM) device that creates three
dimensional objects. It starts with a virtual design of the object to be
printed; the computer software can scan existing items or allow you to create a
unique design. The computer then takes that model and slices it into thousands
of horizontal layers. The printer reads each one of those slices and prints it
out layer by layer to build a solid three dimensional object. This process is
called additive manufacturing.
Many different materials can be used
for 3D printing , such as ABS plastic, PLA, polyamide (nylon), glass filled
polyamide, stereo lithography materials (epoxy resins), silver, titanium,
steel, wax, photopolymers and polycarbonate.
Types of 3d printing
1) Fused Deposition Modelling- It is an additive manufacturing technology commonly used
for modelling, prototyping, and production applications.
2) Stereo lithography- It is an additive manufacturing process which employs a vat of liquid
ultraviolet curable photopolymer "resin" and an ultraviolet laser to
build parts' layers one at a time.
3) Selective laser sintering- It is an additive manufacturing technique that uses a high
power laser (for example, a carbon dioxide laser) to fuse small particles of
plastic, metal (direct metal laser sintering), ceramic, or glass powders into a
mass that has a desired three-dimensional shape
