Rapid Prototyping: A boon during a Pandemic Lockdown

With the situation, we face today of coronavirus, the time for the development of the new product is scarce as the product has to be tested and launched quickly in the market to counter health situation today. The traditional method of manufacturing and testing the iterations seems to be against what is required today as those methods are costlier, time-consuming and difficult due to lockdown situation which makes it difficult for manufacturing moulds, products etc. The traditional method of manufacturing like moulding requires moulds to be produced for the different iterations to be tested which is costlier and may take several days for the product to be manufactured and tested to check on product feature and make changes for desirable results and this long cycle goes on. The lockdown situation makes this process even worse with the unavailability of workers & stringent time factor we are fighting against.

An effective prototype is one that can give product developers an accurate idea of how the final product will perform. Whether that’s reviewing the texture and colour or putting the part up to rigorous testing, engineers need a prototype that’s up to the task. When it comes to product development, time is essence: especially if you had to put design iterations on hold during the lockdown. Rapid prototyping is blessing in disguise to counter the situation. Rapid Prototyping is a group of techniques used to quickly fabricate a scale model of a physical part or assembly using 3D CAD data. Construction of the part or assembly is usually done using 3D printing or additive layer manufacturing technique. Your product development timeframe need not be affected with rapid prototyping at your service. Improving parts with 3D printing is quick, simple and cheaper with much iteration that can be produced and tested as compared to traditional methods. In few hours or a day the original design can be updated on the software and the file can be shared to the manufacturer digitally and the prototype would be in your hands within few hours or days as per the complexity and size of design. The manufacturing errors can easily be eliminated with rapid prototyping as compared to traditional methods of production. The models can easily be scaled as per the need with limitations arriving only at the maximum size of product a given model of machine can produce. Cutting down on costs is necessity for industries battling these tough times but this in sense doesn’t mean to kill innovations necessary for progress.

Rapid prototyping enables innovation with its freedom of design to engineers for manufacturing parts with intrinsic and small detailed designs and geometries with interlocking features which is not possible to manufacture with tradition methods. This helps in creating product assembly with many components into a single component product which in turn saves cost. Additive manufacturing offers huge varied combinations of technologies from laser sintering to fused deposition modelling and materials from aluminium to PA 12 that engineers can choose from to optimize their designs .It provides with variety of textures and colours to choose from. The input files can easily be changed to fulfil design requirements.
