Which of the following is a solid-based rapid prototyping system? Correct Answer Fused-deposition modelling

Rapid prototyping system:-The rapid prototyping is manufacture of a physical item, model, or assembly utilizing 3D computer aided design. Additive manufacturing, often known as 3D printing, is commonly used to complete the construction of the part, model, or assembly.
Different type of Rapid prototyping system:-

1. Stereolithography (SLA) or Vat Photopolymerization
2. Selective Laser Sintering (SLS)
3. Fused Deposition Modelling (FDM) or Material Jetting
4. Selective Laser Melting (SLM) or Powder Bed Fusion 
5. Laminated Object Manufacturing (LOM) or Sheet Lamination
6. Digital Light Processing (DLP)
7. Binder Jetting

Solid -based Rapid prototyping system:-

Solid-based rapid prototyping systems are designed to work with all solid-state materials. The solid form could be in the form of a wire, laminate, pellets, or a roll. Solid-based rapid prototyping systems works on the following principles:

1. Cutting and Glueing / Joining method.
2. Melting and Solidifying / Fusing method

These processes differ from one another, though some of them involve lasers in the prototype fabrication process. They all use solid as the primary medium for prototyping in some way or another.

Fused deposition modelling (FDM) is a popular additive manufacturing technique for modelling, prototyping, and production. Fused Deposition Modelling (FDM) is a technology that creates three-dimensional objects directly from 3D CAD data.
