The cumulative time and cost required to produce prototypes can pose an economic challenge to start-ups. Many national and international companies are now choosing to rely on 3D printing to achieve a balance between economic and time costs.
In an e-mobility project in Austria, designers designed a component to improve the charging efficiency and power of an electric vehicle. The choice was made to print the gears using a laser sintering 3D printer. This approach ensured a high degree of flexibility and fast delivery in the construction of the prototype, and importantly the 3D printed component was tested and found to still function after a million cycles, with almost unmeasurable wear and tear and 2-3 times the durability of traditional processes.
