How is Rapid Prototyping Changing the EV Manufacturing Game

Image 53

The Federation of Automobile Dealer Association (FADA) shared details of the growth of sales in the EV sector, with EV sales increasing threefold from 1,34,821 units a year ago to 4,29,217 units in FY22. This is just one of the countless statistics and studies that indicate the future of the automobile sector.

This growing demand and change are giving birth to numerous EV startups, and the need of the hour for EV companies is coming up with innovative and user-centric EVs. But making a change in the production line or testing a new feature or change means potentially spending tens of lakhs or crores of rupees and dedicating an R&D team to the project.

This was the traditional way of coming up with something new in the automobile sector, but rapid prototyping has changed it all, especially in the 2 and 3-wheeler EV space.

Building fast with Rapid Prototyping

Rapid prototyping for electric two wheelers has made it effortless for EV companies to create and test models of EV parts or complete bodies. You can create models of parts and test them in days rather than months or years (traditionally) using CAD models.

Benefits of Rapid Prototyping and why does it represent the future?

There are numerous rapid prototyping advantages that are changing the EV industry:

  1. Cost savings: To start with, 3D printing offers cost-effective visualisation of your end product. You can replace the cost of manually creating parts with new dies and machines. It also helps you select low-cost and lighter materials.
  2. Faster time to market: Jumping from prototype to production is effortless with 3D printing. You can develop an idea, test and start manufacturing (for example motor manufacturing) in days compared to multiple months or years with traditional manufacturing methods.
  3. Cutting edge manufacturing materials: Additive manufacturing, for example, supports Aluminum, polymers, carbon fibre, and other metals for production. You can choose the best materials for your EV while reducing costs and increasing efficiency. This is especially beneficial for EV motor manufacturers.
  4. Customisations: Customising parts, shapes, designs, or other elements of your EV is effortless and quick with 3D printing. CAD models can be customised in different software, and prototypes can be printed per specific needs.
  5. Lightweight components: 3D printing makes it possible to reduce the overall weight of your EV with lightweight materials without you having to compromise on stability, performance, or safety. It increases overall vehicle efficiency.
  6. Stock and spare part issues: You can print spare parts without investing in huge inventories. CAD models can be saved electronically and used to print parts based on demand.

Steps used in Rapid Prototyping

It is worthwhile to know an example of the processes used in rapid prototyping for electric two wheelers:

  • Creating a CAD model
  • Conversion of file format to .stl, .obj, etc that can be used by slicer software
  • Slicing the 3d object into layers and generating instruction file (g-code)
  • Manufacturing
