Designs are created by the designers keeping in mind the technology going to produce them. Hence the design freedom is limited to the technological capability of the manufacturing process. However, there are no such limitations when the process is additive manufacturing opening unlimited potential of the technology. Making complex shapes, lightweight parts and multi-material components are a few of the key benefits offered by AM.

Designers may face roadblocks while embracing AM because an entirely new thought process is needed while designing components for AM. Applying conventional manufacturing (CNC machining, injection molding) thought processes may not be a wise idea because both CM and AM are entirely different in their approach and considerations. Understanding the design, materials, manufacturing and post-processing are important to the success of the AM processes. Another key advantage of AM can create parts with highly optimized material allocation within the given design space.

Fabricate complex shapes

AM has the capability to create highly complex shapes with enhanced functionality which are not possible by conventional manufacturing process due to various limitations. For example, aerospace parts, strength to weight ratio is the key performance parameter. AM can create high strength complex shapes with reduced weight positively impacting the overall performance. An aeroplane can carry an extra load or could travel an extra distance saving on fuel and carbon emissions. Another example is jewellery, complex and intricate designs can only be produced by AM only. The conventional making process takes a lot of time and manual labour to create the same shape.
