Technologies/Techniques

You-SLS

https://www.indiegogo.com/projects/you-sls-the-first-desktop-open-source-lasersinter

What are the advantages of the SLS process?

Laser sintering allows you to build parts without any design restrictions or the need of support structures, as the powder supports itself. Therefore overhangs of any degree will be built perfectly in unreachable resolution. This is a huge advantage over FDM and SLA machines that are currently popular for home-use. Another huge advantage of SLS over other 3d printing processes is the variety of materials that become printable. Anything that is available as powder, ranging from sugar to professional grade sintering nylon, can be printed. The strength of nylon sintered parts is also well beyond anything that can be created with FDM or SLA machines.

FFF vs SLS vs SLA

http://sd3dprinting.com/fff-vs-sla-vs-sls/

Fused Filament Fabrication (FFF):


FFF is a relatively new method of rapid prototyping which works by laying down consecutive layers of material at high temperatures, allowing the adjacent layers to cool and bond together before the next layer is deposited

Stereolithography (SLA):


SLA is another example of building a model layer by layer, but instead of extruding molten plastic through a nozzle, the process requires a liquid plastic resin called a photopolymer which is then cured by an ultraviolet (UV) laser


Selective laser Sintering (SLS):


SLS is a very exciting technology which directly fuses particles together layer by layer through a high energy pulse laser

ABS  (Acrylonitrile Butadiene Styrene) plastic filament is a polymer
Its strength, flexibility, machinability, and higher temperature resistance make it often a preferred plastic for engineers, and professional applications. The hot plastic smell deter some as does the plastics petroleum based origin. The additional requirement of a heated print bed means there are some printers simply incapable of printing ABS with any reliability.

PLA -Polylactic Acid (PLA) is one of the most popular plastics used for 3D printing.  (but its cheap)
The wide range of available colors and translucencies and glossy feel often attract those who print for display or small household uses. Many appreciate the plant based origins and prefer the semi-sweet smell over ABS. When properly cooled, PLA seems to have higher maximum printing speeds, lower layer heights, and sharper printed corners. Combining this with low warping on parts make it a popular plastic for home printers, hobbyists, and schools. With a little more work, PLA can also be sanded and machined. The lower melting temperature of PLA makes it unsuitable for many applications as even parts spending the day in a hot car can droop and deform.


Most Paint will NOT stick to it, so you need a primer paint (like an auto primer paint).  or use the expensive  games-workshop paint.


Rumor has it a fine airbrushing of paint will work on pla.
