SLS process does not researchers have failed to identify is the severe require any additional support materials as the plastic deformation SPD technique.

A powder itself does the work of support material preliminary evaluation of microstructure and [43]. A simplified version of a Ti- consuming process and requires use 6Al-4V demonstration component was of machining.

Materials used for processing is successfully fabricated. This provides a scope for limited. Still SLS metal parts find its limited developing the different components using application in industrial use. Aerospace grade different materials which may be useful for aluminium and other metals are in development. Conclusions Fabrication technique to provide components The SLS process is a viable time and money well with those of conventionally processed saving method for generating complex prototype material.

The direct implementation of parts in the plastics and metals industries based successive layers of metallic parts in the future on the materials employed in the system. The lead to a replacement casting process for a benefits of using the system include: The ability satisfactory performance in terms of materials to utilize a variety of materials and the future such as copper alloys; titanium alloys, tool steel, ability to expand the variety of materials which fire-resistant steel, and aluminium alloys.

It would appear that DMLS is currently on a threshold between References limited application in prototyping applications [1]. Debasish, D, Fritz, B. P, David. R, Lee. Some of the research concluded that [2]. Kruth, J.

Proceedings of the Institution of Mechanical In view of the above, it can be appreciated that Engineers, Part B: Journal of Engineering there are certain problems, shortcomings or Manufacture, 12 , , pg. Development, CH St. Gallen, Switzerland [6]. Seyed Farid Seyed Shirazi et al. Advanced Materials, Published 5 May Kruth, P.

A finite element analysis of hollow stemmed hip prostheses as a means of reducing stress shielding of the femur. Acta Biomater. SLS is one of the most versatile and commonly used additive manufacturing technologies. Common uses of SLS-printed parts are in airplanes, wearables, machine components, and production tools.

The working principle of 3D printing is the same as that of a traditional printer. The rapid prototyping equipment using light-curing and paper stacking technology superimposes the printing materials layer by layer through computer control and finally becomes a reality. The 3d printing process steps usually include the following main steps: modeling, slicing, printing, and post-processing.

On-demand SLS 3D printing enables you to prototype your product using industrial-quality materials. Improve your designs iteratively to perfect your product before moving to production. Strong and durable, SLS Nylon produces best-in-class working properties that can either be flexible or rigid depending on the geometry of the design. See our datasheets below.

SLS is a viable production method for manufacturing parts at volume. This technology can be used as an alternative to injection molding. Some features of the site may not work correctly.

DOI: Lupone , E. Badini Published 27 December Medicine Materials Selective laser sintering SLS is a powder bed fusion technology that uses a laser source to melt selected regions of a polymer powder bed based on 3D model data. Components with complex geometry are then obtained using a layer-by-layer strategy. This additive manufacturing technology is a very complex process in which various multiphysical phenomena and different mechanisms occur and greatly influence both the quality and performance of printed parts.
