Rapid prototyping is a batch of techniques used to quickly build a model, a physical part of a building using a 3D computer-aided design (CAD). The building model is part is achieved through 3D printing, also known as additive manufacturing. 3D printing involves adding layer-upon-layer of materials to achieve a 3D object which is called a prototype.To know more https://aravindaccurate.com/

How is rapid prototyping changing the future of the manufacturing industry?
What is rapid prototyping? • Rapid prototyping is a batch of techniques used to quickly build a model, a physical part of a building using a 3D computer-aided design(CAD). The building model is part is achieved through 3D printing, also known as additive manufacturing. 3D printing involves adding layer-upon-layer of materials to achieve a 3D object which is called a prototype. • Other technologies used in rapid prototyping include: • Molding • Casting • High-speed machining • Extruding • Prototypes are described as either high-fidelity or low-fidelity prototypes. A high-fidelity prototype is a design that fits the end product idea, while a low-fidelity prototype is when the end-product does not match the initial idea.
Different types of rapid prototyping? • Vat Photo polymerization or Stereo lithography (SLA) • Selective Laser Sintering (SLS) • Material Jetting or Fused Deposition Modelling (FDM) • Powder Bed Fusion (PBF) or Selective Laser Melting (SLM) • Sheet Lamination or Laminated Object Manufacturing (LOM) • Digital Light Processing (DLP) • Binder Jetting
Vat photopolymerization or Stereolithography (SLA) • SLA is an additive manufacturing process that is affordable and fast. It was the first type of 3D printing ever to work. • SLA uses a tank of photosensitive liquid that turns into a solid when in contact with computer-controlled UV light. Once the SLA parts have solidified, they cannot turn back to liquid; the process is irreversible.
Selective Laser Sintering (SLS) • SLS is also an additive manufacturing technology best suited for plastic and metal prototyping. SLS uses a high-power laser to heat and sinter layers of powder to create a prototype. • It is important to note that SLS products are much weaker than SLA prototypes. However, SLS is much cheaper and requires less time and labor while offering high productivity. • SLS parts are rough and require more refining after obtaining the final part.
Material Jetting or Fused Deposition Modelling (FDM) • Material jetting is also an additive manufacturing process that is fast, affordable, easy to use, and cheap. FDM is best used for product development. • FDM creates prototypes using thermoplastic filaments melted inside a printing nozzle barrel. The printer works by moving the nozzle back and forth. By using a computer deposition program, the plastic is layered to form the prototype.
Powder Bed Fusion (PBF) or Selective Laser Melting (SLM) • SLM is the most commonly used type of additive manufacturing. This method is popular in aerospace, automotive, defense, and medical companies. It is the most preferred method because it is less expensive and it makes high-quality parts. • The method uses a high-power or electron beam to melt the binder layered with the powder to create a production part or prototype. • PBF uses powered based materials such as: • Titanium, cobalt chrome alloys • Copper • Aluminum • Stainless steel
Sheet Lamination or Laminated Object Manufacturing (LOM) • Sheet lamination is not as complex when compared to SLS and SLM. This process does not need you to be in a specially controlled environment to achieve your desired results. • Sheet Lamination works by putting together layer-by-layer metal, plastic, and ceramics cuts using laser beams to create the desired CAD design. Each layer is bonded with glue till the whole component is finished. However, this method is labor-intensive and takes a lot of time.
Digital Light Processing (DLP) & Binder Jetting • DLP is almost the same as the SLA method. DLP used polymerization of resins that are solidified using a beam of light. • The light source in DLP comes from a projector, while the light source in SLA comes from laser beams. DLP is cheaper and quicker than SLP, but it needs more infrastructure in terms of post-build curing. • Binder jetting is also an additive manufacturing process that allows more than one part to be printed simultaneously. Parts created in this process are not as strong as this of the SLS process. • Binder Jetting works by spraying liquid binding agents using nozzles to join powder particles, creating a one-piece layer.
Industrial applications of rapid prototyping? • Making of drones. • Developing aerospace and defense equipment. • Designing medicine devices. • Used in making automotive parts.
