Do you heard about 3D printer? Printer was the machine
that draw on paper what words and images displayed on monitor. As the printer,
3D printer prints 3-dimensional thing by looking at the three-dimensional
design view depicting a particular software. The early 1980s 3D printer was
made first by 3D Systems Co.
What is the
principle that 3D printer prints things? 3D printer analyzes finely cut thing
laterally 10,000 or more. And completed from the bottom of a very thin membrane
and layers by stacking products to the top. This 3D printer developed to date,
build up height 2.8cm per hour. Material entering the 3D printer is mainly
powder and liquid, and yarn. Solidify powder and liquid, and dissolved a very
fine layer. Then stacking the countless layers by making things.
Creating purpose of the 3D printer, was to make a prototype before
issuing the goods. Creating a prototype in its entirety is formed at a low cost
easy to materials, it is possible to know that there is any problem in the
actual product. It’s 3D printer’s representative merit.
And it can make complex things. Dr. Stefan Danforth, New Jersey
State University, says “It’s possible that making difficult by hand or complex
shape can be printed at a time. The things that can make 3D printer are
virtually infinite.” Recently, the European aviation defense industry (EADS)
was named "air bike" by printing a bicycle in a 3D printer. The
reason that the air bike is special is not to assemble wheels, pedals, and
saddle when creating a separate body, but to have printed a single bicycle
finished product. So expert expects to be able to produce efficient products by
reducing the existing complex production process by using 3D printer.
However, 3D printer’s dark side also present. These are infringement duplication and
illegal firearms production problem. Infringement duplication is open to become
social problems be-cause it infringes the copyright that is associated with the
product. Also, the illegal firearms manufacturing problem, by using a 3D
printer, it is possible to mass produce anything gun if they have three
dimensional designed.
Also 3D printer’s disadvantage are high cost and poor durability. And take long time
to complete also disadvantage.
3D printer’s technology is day-to-day development. Experts, already realize
funny magic such as come out chocolate drinks beginning to the mug. Of course,
all of this is done simply by pressing the ‘Print’ button. The future
is approaching more and more where you can enjoy a morning coffee with strange
form of cup, the perfect sweets cookie, and every morning wearing only one of
the clothes in the world. It’s why that day is
awaited ‘to become each
household have one of 3D printer.’
