People here are "making" their own
toys and household items without stepping into a shop. All they need to do is
to click on a digital design they desire, from websites dedicated to the
sharing of such files, print it on their 3-D home printer and - presto - the
digital design will be physically transformed into a solid object made of
sturdy plastic.
Developed in the 1980s, 3-D printers build tangible
objects from computer design by repeatedly depositing thin layers of material
one over the other, layer by layer, to form a three-dimensional object.
3-D home printers use plastic materials such as ABS
(acrylonitrile butadiene styrene) and biodegradable bioplastic called PLA
(polylactic acid), which gives the product a glossier finish. They usually
cannot print products longer, taller or wider than 20cm. Depending on the
density of an object and the details needed, printing can take between one and
six hours or more.
Now3-D home printer can cost more than US$2,000 (S$2,499). But if
that’s too X, you could just pass a 3-D file of your design to companies which
offer 3-D printing services and get your prototype within a couple of hours or
days, depending on how big the item is.
Unlike home models, professional 3-D printers cost
between $90,000 and $1.5 million. Highly precise, they can capture details such
as the dimply texture of orange skin or the finer texture of hair.
Printing industry insiders estimate that about 40
home printers are being sold here every month, up from about 20 in 2011. It is
believed that home printers first arrived in Singapore around 2008, through
orders placed on online stores, mostly American ones.
At least two companies here started selling home
printers recently. SG Tooling at Fook Hai Building in South Bridge Road started
with DIY 3-D home printer kits from local company OrangeKnob LLP last year. It
has since switched to, and now sells only, American brand MakerBot, the market
leader in ready-made home printers. It is its main distributor here. The MakerBot Replicator 3-D home printer costs
between US$2,199 and US$2,799.
DIY 3-D home printers such as Panther 3-D printer
can be bought from OrangeKnob LLP, believed to be the only local maker of 3-D
home printers here. Its home printers are said to cost between US$480 and
US$960.
Another local firm Pirate3D, which has an office in
Mountbatten Road, is developing what it hopes will be the world's most
affordable 3-D printer, the Buccaneer. It is estimated to cost about US$347.
The 3-D printer-making company made its debut
recently on online crowd funding site Kickstarter.
