Factors to consider while choosing the right manufacturing techniques
If we talk about 3D printing, it creates three-dimensional object from computer design using various 3D printing methods like SLS (Selective Laser Sintering) printer or FDM (Fused Deposition Modeling) printers etc. 3D printing is seen as a cost-effective way to make parts but I think it has is own limitations. 3D printing factors that we should consider while putting injection molding on the same page depends majorly upon batch size or the production volume, repeatability, material type and the rigidity of the material.
On the other hand, injection molding needs an initial big investment in terms of injection machine and the critical part that is injection mould. Imagine you have an initial order for say 1000 parts and you have to send 10 piece prototypes for inspection with in a limited time. Now if you follow to make an injection mould, it has a minimum lead time of 4-6 weeks – then molding, finishing and inspection. Also if some discrepancies come up, all of these process go to waste and you will have to start from the beginning. Here if you take the 3D printer, you can have rapid prototyping within some hours to a day in large cases depending upon the complexity of geometry.
