The purpose of this paper is to describe the basics of selective laser sintering SLS and also the benefits of designing parts to be built using this technology. Some design requirements are also included. This paper was written to assist design engineers in using the SLS technology as opposed to traditional manufacturing technologies.

About SLS , Knowledge 0 comments. It uses thermoplastic materials, typically in the form of spools of filaments. The heated nozzle of the extruder melts the material which is then deposited onto a substrate. There are several advantages of FDM. The majority of printers are desktop-sized which makes them ideal for the office.

The demand is growing due to some of the revolutionary benefits that it can provide. Like almost all technologies it has its own drawbacks that need considering. This page aims to help with the selection process. We will cover each of the advantages and disadvantages of 3D printing. This production process offers a range of advantages compared to traditional manufacturing methods. These advantages include those related to design, time and cost, amongst others.

Written by Alkaios Bournias Varotsis. In SLS, a laser selectively sinters the particles of a polymer powder, fusing them together and building a part layer-by-layer. The materials used in SLS are thermoplastic polymers that come in a granular form. SLS 3D Printing is used for both prototyping of functional polymer components and for small production runs, as it offers a very high design freedom, high accuracy and produces parts with good and consistent mechanical properties, unlike FDM or SLA. The capabilities of the technology can be used to its fullest though, only when the designer takes into consideration its key benefits and limitations.

What are the Advantages and Disadvantages of 3D Printing?

Selective laser sintering SLS is an additive manufacturing AM technique that uses a laser as the power source to sinter powdered material typically nylon or polyamide , aiming the laser automatically at points in space defined by a 3D model , binding the material together to create a solid structure. It is similar to selective laser melting ; the two are instantiations of the same concept but differ in technical details. SLS as well as the other mentioned AM techniques is a relatively new technology that so far has mainly been used for rapid prototyping and for low-volume production of component parts. Production roles are expanding as the commercialization of AM technology improves. Selective laser sintering SLS was developed and patented by Dr. Carl Deckard and academic adviser, Dr.

All About SLS Printing: Advantages, Disadvantages, History, and more

Since most starting materials for tissue engineering are in powder form, using powder-based additive manufacturing methods is attractive and practical. The principal point of employing additive manufacturing AM systems is to fabricate parts with arbitrary geometrical complexity with relatively minimal tooling cost and time. Selective laser sintering SLS and inkjet 3D printing 3DP are two powerful and versatile AM techniques which are applicable to powder-based material systems. Hence, the latest state of knowledge available on the use of AM powder-based techniques in tissue engineering and their effect on mechanical and biological properties of fabricated tissues and scaffolds must be updated. Additive manufacturing AM is a technique for fabricating parts in precise geometry using computer aided design CAD and computer aided manufacturing CAM [ 1 ].

Stereolithography SLA comes as a distant second. Identifying which technology comes third is far from definite, but a strong case could be made for Selective Laser Sintering SLS. What is SLS and how does it work?

Selective laser sintering

Additive manufacturing commonly referred to as either rapid prototyping or 3D-printing is used to construct simple and complex geometries by fusing together very fine layers of powder or liquid. Each cross-section is mapped onto the surface of the rapid prototyping material by a laser, which fuses or cures the particles together. The layers are in the XY plane while the part is being built in the Z direction. Each of these cross-sections represents a layer in the build.

Беккер поморщился. - Предпочитаю вид спорта, в котором я могу выиграть. - Победа любой ценой? - улыбнулась Сьюзан. Защитник Джорджтауна перехватил опасную передачу, и по трибунам пронесся одобрительный гул. Сьюзан наклонилась к Дэвиду и шепнула ему на ухо: - Доктор. Он смотрел на нее с недоумением.
