LS production parts are strong, water and air-tight, heat resistant and repeatable. If the user has a need for a different plastic for a specific application.Laser Sintering (LS) is a way to build prototypes early in the design cycle or production parts in a wide variety of applications. It offers far superior living hinges, snap-fit, and other mechanical joints than any other technology.Above: An Example of SLS 3D Printer – The Formlabs Fuse 1 SLS 3D Printer Image Credit FormlabsSLS 3D printers mainly use nylon powders or polymers with similar properties to nylon. Our customers count on this robust SLS printer for the toughest applications, year after year. Impact-Resistant, Durable Parts. 3D Systems sPro 140 Prints in a Range of Production-Grade Duraform Nylon Materials.
Multiple technologies have emerged over the years such as FDM/FFF, DLP, SLS, Binder Jetting, Rotational 3D printing, Cold Spray AM, and many more. Experts believe that it has ushered the 4th Industrial revolution and will prove to be one of the most revolutionary technology ever developed.3D Printing is not a single process but a set of technologies which operate on similar principles of additive manufacturing. Laser Sintering 3D Printer SLS Nylon Ink Coating PA11 PA12 Powder for EOS.This article focuses on one of the most widely used 3D printing technologies in the world i.e., Selective Laser Sintering (SLS) 3D Printing technology.Additive Manufacturing, or 3D Printing as it is most popularly known, is a rapidly evolving technology. We manufacture and sell 3D printer filament that will fulfil your 3D printing needs.
Most common material is Nylon PA12Roller or Leveller: This transfers new layer of material from the powder delivery system and spreads it evenly on top of the previously printed layer in the build chamber for next printing cycle. THE COMPONENTS OF SLS 3D PRINTER Above: A Diagrammatic representation of the working of Selective Laser Sintering TechnologyLaser: This is a powerful laser which is used to melt the particles to fuse them togetherScanning System: This system perfectly directs the laser to the desired location and then traces the geometry for each layer.Build Chamber: This chamber houses the powdered materialPowder Delivery System: The powder delivery system is responsible for carrying and delivering the powder for each layer of printing.Powdered Material: This is the actual material in its powdered form.

This process continues till the complete object gets printed. This time the adjacent particles are fused together along with the fusion of current and previous layer forming two completely bonded layers. The laser again starts and traces the next layer of the material in the build chamber. In an SLS machine, almost all of the parameters are preset by the machine manufacturer and there is a limitation on the manual modifications by the machine operator.Once the bed drops, the roller brings a new layer of powder to the build chamber again and spreads it on top of the previous layer. The default layer height used in SLS printing 100 μm. This completes printing of the first layer.On completion of the first layer, the laser pauses and the build chamber drops down by approximately 50 to 100 μm.
This proves to be a double-edged sword.Since the chamber has to be filled with powder, the material is heated every time an object is printed. MORE ABOUT SELECTIVE LASER SINTERING (SLS) TECHNOLOGYSince Selective Laser Sintering uses materials in a powdered form and the printing occurs inside a build chamber, the build chamber is always filled with the material. It can be further post-processed by bead blasting, dyeing, painting, powder coating, tumbling, stove enameling, metal coating, lacquering, etc. Parts made in SLS machines are gritty but are layer lines are not as prominent as in the case of FDM. Once the part is removed it is cleaned by blasting it with compressed air. This can take a significant amount of time.

Which publishes the latest 3D printing news, insights and analysis from all around the world. Therefore, Aerospace industry is the biggest beneficiary of this technology.About Manufactur3D Magazine: Manufactur3D is an online magazine on 3D printing. This helps in optimum use of the machine and material.Selective Laser Sintering is most suited for a single piece or small quantity production of high-quality parts. And positively, since the powder engulfs the object, it can be used to build several parts simultaneously in a single run.
