This paper discusses the results obtained from studies on different rapid tooling process chains for improved design and manufacture of foundry equipment for sand casting of prototypes in final material for functional and pre-production tests of vehicles, using the three-dimensional printing process as core technology. Subsequently, while considering aspects such as time, cost, quality (accuracy and surface roughness), and tool life, a framework for evaluation and selection of the most suitable process chain in accordance to specific requirements is presented. Apart from only using these process chains for prototype manufacturing, initial results from a study to apply one of these process chains in automated sand casting full production is also presented. This research builds on an in-depth characterization of the accuracy and repeatability of a three-dimensional printing process.

The three-dimensional printing is a manufacturing method involving the addition of materials by using certain principles valid in printing techniques. There are various techniques of a three-dimensional printing method and the most of them could be applied inclusively to generate objects of polymers. The objective of the research presented in this paper was to analyze the capabilities of 3D printing process or equipment of generating fine details and to identify a way of evaluating these capabilities when using polyester PLA as filament material. The systemic analysis of the printing techniques which use a fused polymer filament deposition showed that there are some groups of factors able to affect the obtaining of fine details. An experimental research was designed in order to highlight the influence exerted by the diameter of the nozzle orifice and by the values of sharp angles of isosceles triangles on the heights of these triangles, thus obtaining an image concerning the possibilities of generating sharp edges by three-dimensional printing. To evaluate the capacity of the 3D printing process of obtaining thin walls, a spiral including linear segments with a decreasing thickness from 1 mm was also achieved on the test piece. By mathematical processing of the experimental results using a specialized software, empirical mathematical models were determined to evaluate the intensity of influences exerted by the two process input factors on the heights corresponding to isosceles triangles characterized by sharp angles.

Three-dimensional printing technology based on deterministic electrochemical deposition method has been developed, which is generated from the electroplating. The traditional electroplating system has been improved to ensure the printing process controllable. Through accurate control of the deposition region, deposition rate, and the dwelling time in the printing process, a three-dimensional object of almost any shape can be obtained by deterministic manufacturing process. Through addition of alcohol to the electrolyte, Marangoni effect is generated, which will improve the property of the deposited layer. The deterministic electrochemical deposition not only can decrease the cost of the printing process, but also will promote the application of the 3D printing technique in many fields.
