Different Types

At present, the development of techniques and technology can’t do without innovations in production. This explains the desire of mankind to look for innovative ways to produce different types of products. One of these systems is the production method of selective laser sintering. It is more promising as compared to other rapid prototyping techniques, due to the relative cheapness of materials and time-consuming to produce finished products. This article discusses the method of selective laser sintering, its advantages and disadvantages.

Slurry Layer

This research developed a feedback control system of laser compensation for the rapid prototyping (RP) machine using layer-wise slurry deposition and selective laser sintering (SLS). The slurry was prepared by silica power and silica sol with 60 and 40 wt.% with suitable rheological properties for 0.1 mm layer deposition. Four ceramics for comparison of the formability of fabricated ceramic green parts with/without the feedback control system of laser energy density for models were designed With this laser feedback control, batter quality ceramic green parts can be manufactured and the rapid prototyping machine with steady laser energy radiated on slurry layer was achieved. Experimental results validate the well performance of the measuring laser power and feedback control system.

Rapid Prototyping System

Selective laser sintering (SLS) is one of relatively mature rapid prototyping technologies at present day. This paper takes the forming of a high voltage switch casting model in the AFS-3000 rapid prototyping system as example to describe the forming process of SLS, and introduce the casting model rapid prototyping technology based on SLS. This research provides a powerful technological support for rapid development of casting products.

Deposition Modeling

A class of technologies referring to Rapid Prototyping (RP) or Additive or Layer Manufacturing or 3D Printing allows designers to quickly create tangible prototype instead of using two dimensional pictures. This technology produces models and prototype parts from 3D CAD model data created from 3D object digitizing systems. Rapid Prototyping forms parts by joining together liquid, powder or sheet materials. Physical models are built using three basic stages: pre-processing, building, post-processing. Pre-processing consists of generation of CAD model, convert into STL format and slice the STL files into cross sectional layers. In building process, construction of model takes place one layer atop another. Post process consists of cleaning and finishing the final model. Common types of Rapid Prototyping technologies popular in industry are: Steriolithography, Fused Deposition Modeling, Selective Laser Sintering, Laminated Object Manufacturing,3 D Printing. The selection of the processes depends upon the material to be cured to build the final model. Rapid Prototyping technologies are used in various industries like Automobiles, Consumer products, Medical, Academics, Aerospace, Government and Military. This poster talks about few challenges to be considered in Rapid Prototyping like shrinkage and distortion of final model, mechanical performance of RP model and limitations to mass quantity. : Layer Manufacturing, CAD Model, STL format, Steriolithography, Fused Deposition Modeling, Selective Laser Sintering.
