Designing projects via 3D printing

When it comes to innovations in the construction industry, 3D printing is one of the most talked-about in recent years. In this blog post, Reddy Kancharla will be talking about how 3D printing aids in designing buildings.

3D printing is the process of printing and creating solid objects in three dimensions from a digital file. It involves taking an object or data in digital form and recreating it using a 3D printer, thus producing a physical version of the object.

Below are three ways 3D printing can help design structures.

1. Fused deposition modeling (FDM): This fabrication method was initially used for rapid prototyping and later adopted by the 3D printing industry. It works on an additive process where objects are produced by laying down successive layers of material until the complete part has been formed. Filament or wire-like thermoplastic or acrylonitrile butadiene styrene (ABS) is the source material, and it acts as a glue or a binding agent for these layers.

2. Selective laser sintering (SLS): In this process, a high-powered laser selectively fuses fine particles of plastic, metal, or ceramic powders to form a 3D object.

3. Stereolithography (SLA): This additive process utilizes a UV laser to trace the cross-section of an object onto a vat of liquid photopolymer resin, causing the resin to selectively solidify and form a layer of the intended 3D object. This process is repeated for layers upon layers until the full 3D object is formed, Reddy Kancharla adds.
