Combination of 3D printing and injection molding: Overmolding and overprinting

Abstract: Nowadays, two of the most important polymer processing technologies are injection molding and 3D printing. Injection molding is ideal for mass production, while 3D printing is ideal for producing products with a complicated geometry. When these two technologies are combined, such complex products can be manufactured economically that would be too costly if produced traditionally. We present the possibilities of combining injection molding and 3D printing. We introduced a novel concept to study and compare the … Show more

“…Optimising the fibre alignment within each layer to alternating orientation from point to point has not been adopted, albeit due to the nonavailability of necessary commercial tools. Moreover, MEX composite parts are fairly lucrative in terms of overall economics but have poor mechanical and thermal material characteristics [ 12 , 13 ].…”

“…However, AM’s bottleneck is the production rate in the long run, which is three to four orders of magnitude slower than that of injection molding [ 6 ]. A combination of a relatively high production rate and customized production can be achieved with hybrid technologies, where several plastic processing techniques are combined to manufacture a single part [ 7 , 8 , 9 , 10 ].…”

“…This method allows engineers to generate products with three‐dimensional complex geometries. [ 30 ] The high‐pressure shear flow in the closed cavity has a profound impact on the structure and properties of polymers. The complex injection molding process has attracted widespread attention in academia and industry.…”
