Abstract
¡®Three dimensional (3D) printing¡¯ is defined as a technology to
use a 3D modeling designed by a computer or a solid state of
model data produced by a digital 3D scanner and to convert
into a physical model which is directly touchable by hand

through a mechanically stacked formation (layer by layer).
The 3D printing technology was invented by Charles W. Hull
in US, and the first commercial 3D printing equipment was
made available in 1988. For the last 26 years it has made a
rapid development in many areas such as processing, material,
software and related infrastructure, so as to emerge as a key
technology that will bring an innovation in conventional
manufacturing processes and a great change in future life that
we never imagined in the past.
The biggest change in the manufacturing industry is to make a
mold production of any shape possible, which was impossible
in the past without the 3D printing technology, if a 3D digital
modeling process of the shape is possible. In addition, the
initial level of modeling techniques now available has reached
to a level of making a directly usable product, so as to properly
make a 1:1 ??customized production or a small quantity batch
production for a variety of products in near future. These
phenomena will be reflected as an increase in the number
of pro-sumers and individual manufacturing enterprises
who make production and consumption at the same time.
On top of it, an easy digital data storage and transformation
and a long-distance transportation innovation will bring an
economic benefit soon by significantly reducing the heavy
long-distance shipping and warehousing costs that result from
the traditional manufacturing supply chain logistics.The 3D
printing technology is also an essential technology to meet
the environmentally safe management bases like global low-
carbon green growth and sustainable production movements
for the protection of global environment.
Currently, approximately 20 kinds of 3D printing methods
and systems are in active use, including some exemplary
schemes like SLA, SLS, FDM, DLP, POLYJET, etc. along with
a variety of materials like metal, plastic, rubber, silicon, wood,
ceramic and concrete. Recently, bio-diverse and human 3D
printing researches have been on-going to make human
body tissue, skin, blood vessels and even organs. Besides, a
food printer has also appeared to 3D digitally print foods like
chocolate, cookies, pizza, etc. The prevalence of a diffusion-type
3D printer give wings to the rapid popularization of 3D printing
technology in many application fields.
Those applications of the 3D printing technology are in a
very wide range covering electrical and electronic consumer
products, automotive, aerospace, medical and dental devices,
military equipment, architectural models and education tools.
In particular, the present discussion is made specifically in
the field of architectural BIM (Building Information Modeling)
and its related 3D printing technology on which an active
research has been made recently. Additionally, the 3D printing
technology is developed from a level of the past architectural
modeling production up to that of the current and future
architectural buildings where moon rocks are used to make
a moon base construction. Therefore, in this paper new
possibilities of the 3D printing technology are studied on future
architecture and construction fields, manufacturing of plastic
and metal subsidiary materials and setting-up of concrete
buildings using the concrete printer.
