Abstract In this paper, the application of Rapid Prototyping in the fabrication of a robotic hand is presented. Using the Selective Laser Sintering Sinterstation 2000 of DTM Corporation of Austin, TX, prototypes of mechanical joints were fabricated experimentally. The designs of these component joints were then used to fabricate the articulated structure of one four degree of freedom finger of a five-fingered robotic hand. This robotic finger and joints have been fabricated in one step, without requiring assembly while maintaining their desired mobility.

In this paper, the application of Rapid Prototyping in fabricating non-assembly robotic systems and mechanisms is presented. Using two Rapid Prototyping techniques, Stereolithography and Selective Laser Sintering, prototypes of mechanical mobile joints were fabricated. The designs of these component joints were then used to fabricate the articulated structure of experimental prototypes for two robotic systems: (1) a three-legged parallel manipulator, (2) a four degree-of-freedom finger of a five-fingered robotic hand. These complex multi-articulated, multi-link, multi-loop systems have been fabricated in one step, without requiring assembly while maintaining their desired mobility. The feasibility and usefulness of Rapid Prototyping as a method for the fabrication of these non-assembly type mechanisms and robotic systems is the focus of this work.

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.

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.
