“…based on the same material phase change properties, in which a photosensitive polymer resin is exposed to a low-power laser. Laser polymerisation is used for polymers resins having low strength therefore, used in the field of prototyping and non-structural applications (Pham and Gault, 1998;Corbel et al, 1994;3D Systems, 2018;Zhang et al, 2002;Singh et al, 2012). Stereo-lithography, direct laser printing, continuous liquid interface production by Carbon and daylight polymer printing by Photocentric are the variants of vat polymerisation [Figure 4(c)] (3dexperience, 2019).…”

Purpose This paper aims to present a systematic approach in the literature survey related to metal additive manufacturing (AM) processes and its multi-physics continuum modelling approach for its better understanding. Design/methodology/approach A systematic review of the literature available in the area of continuum modelling practices adopted for the powder bed fusion (PBF) AM processes for the deposition of powder layer over the substrate along with quantification of residual stress and distortion. Discrete element method (DEM) and finite element method (FEM) approaches have been reviewed for the deposition of powder layer and thermo-mechanical modelling, respectively. Further, thermo-mechanical modelling adopted for the PBF AM process have been discussed in detail with its constituents. Finally, on the basis of prediction through thermo-mechanical models and experimental validation, distortion mitigation/minimisation techniques applied in PBF AM processes have been reviewed to provide a future direction in the field. Findings The findings of this paper are the future directions for the implementation and modification of the continuum modelling approaches applied to PBF AM processes. On the basis of the extensive review in the domain, gaps are recommended for future work for the betterment of modelling approach. Research limitations/implications This paper is limited to review only the modelling approach adopted by the PBF AM processes, i.e. modelling techniques (DEM approach) used for the deposition of powder layer and macro-models at process scale for the prediction of residual stress and distortion in the component. Modelling of microstructure and grain growth has not been included in this paper. Originality/value This paper presents an extensive review of the FEM approach adopted for the prediction of residual stress and distortion in the PBF AM processes which sets the platform for the development of distortion mitigation techniques. An extensive review of distortion mitigation techniques has been presented in the last section of the paper, which has not been reviewed yet.

Rapid manufacturing is a new mode of operation that can greatly improve the competitive position of companies adopting it. The key enabling technologies of rapid manufacturing are rapid prototyping (RP) and rapid tooling (RT). This paper classifies the existing RP processes and briefly describes those with actual or potential commercial impact. The paper then discusses five important RP applications: building functional prototypes, producing casting patterns, making medical and surgical models, creating artworks and fabricating models to assist engineering analysis. Finally, the paper gives an overview of indirect and direct RT methods for quickly producing up to several thousand parts together with examples illustrating different applications of RT.

Computer-aided manufacture of three-dimensional objects by laser space-resolved photopolymerization

Abstract: Abstract. The local absorption of the light of suitable energy can lead to the polymerization of a liquid monomer. By moving the incident laser beam, one can create objects of very fine quality. This idea is the basis for the computer-aided manufacture of three-dimensional objects.
