In order to build 3D structures and objects, various 3D printing methods are developed. Though a few have fallen by the wayside, quite a number of them are widespread nowadays. Want to know how much does a 3D printer cost? A well-known online 3D printer guidance website comes with up-to-date information.
The guide given below focuses on a few popular types of available 3D printing technologies or as in the words of a layman, types of 3D printers.
Stereolithography / SLA
It is a 3D printing method which can be used to execute those projects which requires the 3D printing of items. The SLA 3D printing machines don’t work like the normal desktop printers. They function with an excess of liquid plastic that hardens and forms to a solid object after a while. The parts printed by the SLA 3D printers normally have smooth surfaces.
Fused deposition modeling / FDM
Originally developed and implemented by Scott Crump, this technology was founded in the year 1980. With the help of FDM, you can print not only just operational prototypes but also ready for use products like plastic gears, lego and much more. It is the only technology which uses production grade thermoplastics so items printed have terrific chemical, thermal and mechanical attributes. The FDM 3D printer cost starts around $2500.
Digital light processing / DLP
This process is quite similar to that of stereolithography. Digital light processing utilizes digital micro-mirrors laid out on a semi conductor chip and is found in film projectors, mobile phones and of course in 3D printing. The printing speed is the kicker. In a few seconds a layer of hardened material can be produced with this type of printer.
Selective laser sintering / SLS
In order to form strong 3D printed objects, Selective laser sintering is a technique that uses a laser as a power supply. SLS does not need to use some other support structures as the object which is being printed is surrounded by un-sintered powder. This technology is quite popular with 3D printing customized goods due to a large selection of materials which may be used with this sort of 3D printer.
