3D Printer (3DP) is an new printer that can print the shape of
any object , but 3D printing can only print the shape of the object, it can’t
brint the function of the object. It is widely used in model design,
education, medical, industrial samples building etc.
A
3D printer, also known as a 3D printer (3DP), is a kind of cumulative
manufacturing technology, or rapid prototyping technology. It is a digital
model based file, using special wax, powder metal, plastic and other adhesives
to create three-dimensional objects by printing layers of adhesive materials.3d printers are now used to make products. The technique of constructing objects by printing them layer
by layer. The idea behind a 3D printer
is to put data and raw materials into a 3D printer, and the machine is
programmed to build the product layer by layer.
The
biggest difference between 3D printers and traditional printers is that the
"inks" they use are real raw materials, stacked in a variety of
forms, and can be printed in a variety of media, from a wide range of plastics
to metals, ceramics and rubbers. Some printers
can also combine different media to make an object hard at one end and soft at
the other.
Types
of 3D Printers
1) FDM printer, Fuse Deposition Modeling, the most polupar printers on the market.
FDM printer is rapidly formed by molten deposition, mainly ABS and PLA.The advantage is that it's cheap and you can print anything
you want.Disadvantages are low accuracy,
slow printing speed, too rough surface.
2) SLA printers, Stereolithography, which are also relatively more widely seen in
the market, mainly model players and families buying desktop-grade SLA printers. This type of printer is formed by light curing via lcd
screen and it is mainly made of photosensitive resin.
The price is a bit more expensive than the FDM printer, but it has high
accuracy and can meet the needs of model players and home users.
3) 3DP printer, which is relatively rare in the market and
mainly used for industrial production, because the price is relatively
expensive, families and schools generally will not buy this type of printer.These printers are bonded by a three-dimensional powder.Main materials powder materials, such as ceramic powder,
metal powder, plastic powder.
4) SLS printer, seen in
the market relatively few, mainly for industrial production and military
industrial production.This type of printer is mainly
made of powder materials through selective laser sintering.
5) LOM printer, which is relatively rare in the market. This
type of printer is not needed in our daily life, but it still has its value.This kind of printer is divided into solid manufacturing,
main material paper, metal film, plastic film.
6) DLP printer, the market also relatively more, less domestic
sales, foreign sales relatively more, this kind of printer through light curing
molding, the main material photosensitive resin.It
is highly accurate and can meet the needs of both model players and home users.These printers are similar to SLA printers.
7) FFF printer, is also more printers seen on the market. FFF printer is manufactured by fuse, mainly PLA, ABS.It's cheap and you can print anything you want. Disadvantages are low accuracy, slow printing speed, too
rough surface.Similar to the FDM printer.
The eighth category is the EMB printer, which is mainly used in
the human skeleton and military aerospace industries.
EMB printers are made of titanium alloy by electron beam fusion.
Here we suggest some lcd screens that suitable for SLA 3D
printer:
The SLA 3D printer lcd screen is used under the extremly UV light environment, it bring high challenge to the life time of LCD screen, because the regular LC materials is hard to stand the strong UV light for a long time, a traditional lcd screen might be only stand 500 hours under strong UV light environment, while the 3D printer lcd screen, it takes anti-UV materials to make the screen, it can stand more than 5000 hours under extremly UV light environment.
The transmissive ratio of 3D printer lcd screen is also very import for industrial 3D printer, a high transmissive ratio of 3D printer lcd display can speed up the curing time of 3D printer. if use the trandistional TFT lcd screen as 3d printer lcd display, its curing time would be around 15s, while if use 3D printer lcd screen, it curing time only 1~2s, because 3d printer lcd display has high transmissive ratio than traditional lcd screen.
The high resolution of 3D printer lcd screen is also important, the high resolution would bring higher texture quality that you printing
