“…Laminated object manufacturing is suited for building of medium‐ to large‐scale prototypes because profile cutting is required without extensive filling operations as in other techniques . Furthermore, relatively large parts may be made, because no chemical reaction is necessary . Other advantages of LOM include low internal tension and fragility of the parts, high surface finish details, and lower material, machine, and process costs …”

Three‐dimensional printing (3DP) technologies, which are sets of powerful deposition methods employed to fabricate 3D objects with materials in the fields of material sciences and engineering, biomedical and biocompatible structural components, automotive, aviation, and polymers, among others, are currently rapidly developing manufacturing technologies. The methods have significant advantages, which include designing flexibility, enhanced geometrical freedom, low cost, and net shape manufacture, among others, over the traditional “subtractive” method. This review highlights the major 3D printing techniques, especially in the fields of advanced polymeric material fabrication and engineering, as well as the synergy in the incorporation of different types of polymeric materials and composites in a process that will lead to an enhancement of dimensional accuracy for 3D technologies. Furthermore, composite ink systems especially polymer‐based and hydrogel‐based in tissue engineering applications are also discussed.

“…The single pattern (casting model) can be 3D printed from materials characterized by low ash-free burnout [ 13 , 21 ], e.g., high impact polystyrene (HIPS), acrylonitrile butadiene styrene (ABS), photopolymer casting resin (ash content thermogravimetric analysis (TGA) 0.0–0.1%) [ 22 ]. The most commonly used 3D printing techniques for disposable casting patterns are: fused deposition modelling (FDM), stereolithography (SLA) [ 23 ], SLS (selective laser sintering) [ 24 ], daylight polymer printing (DPP) [ 25 ] and digital light processing (DLP) [ 26 ].…”

Heat Transfer Analysis of 3D Printed Wax Injection Mold Used in Investment Casting

et al. 2022

Investment casting is one of the precise casting methods where disposable wax patterns made in wax injection molds are used to make a casting mold. The production capacity of precision foundry is determined by the time taken for producing wax patterns, which depends on the time taken for wax solidification. Wax injection molds are usually made of aluminum or copper alloys with the use of expensive and time-consuming computer numerical control (CNC) processing, which makes low-volume production unprofitable. To reduce these costs, the authors present a heat transfer analysis of a 3D printed wax injection mold. Due to the low thermal conductivity of the photopolymer resin, the influence of different cooling channels’ shapes was investigated to improve the time of the manufacturing process. Transient thermal analysis was performed using COMSOL software based on the finite element method (FEM) and included a simulation of wax injection mold cooling with cold air (−23 °C), water, and without cooling. The analysis showed that use of cooling channels in the case of photopolymer material significantly reduces the solidification time of the sample (about 10 s shorter), and that under certain conditions, it is possible to obtain better cooling than obtained with the aluminum reference wax injection mold (after approximately 25–30 s). This approach allows to reduce the production costs of low-volume castings.

“…The competitiveness of enterprises is very often associated with the implementation of the newest manufacturing techniques and corresponding control techniques, which translates into easier and faster satisfaction of the increase in customer requirements for manufactured products. At the same time, the development of more and more complex products entails the necessity to produce prototypes whose properties will correspond to the production (final) part as much as possible [1,2]. One of the techniques allowing for small-lot and accurate production of complex-shaped castings is the investment casting method [3], both in the traditional form and in the version based on 3D-printing technology [4].…”

Non-Contact Multiscale Analysis of a DPP 3D-Printed Injection Die for Investment Casting

et al. 2021

The investment casting method supported with 3D-printing technology, allows the production of unit castings or prototypes with properties most similar to those of final products. Due to the complexity of the process, it is very important to control the dimensions in the initial stages of the process. This paper presents a comparison of non-contact measurement systems applied for testing of photopolymer 3D-printed injection die used in investment casting. Due to the required high quality of the surface parameters, the authors decided to use the DPP (Daylight Polymer Printing) 3D-printing technology to produce an analyzed injection die. The X-ray CT, Structured blue-light scanner and focus variation microscope measurement techniques were used to avoid any additional damages to the injection die that may arise during the measurement. The main objective of the research was to analyze the possibility of using non-contact measurement systems as a tool for analyzing the quality of the surface of a 3D-printed injection die. Dimensional accuracy analysis, form and position deviations, defect detection, and comparison with a CAD model were carried out.
