There are different types of 3D printing. However, the basic principle is the same. Each layer of the three-dimensional model to be made is built layer by layer. The most common (and readily available) type of 3D printing is Fused Deposition Modelling. (see answer to question 3.). Resin printing (known as SLA or MSLA) is fast becoming the preferred choice for many models, due to resolution and speed. (see answer to question 4.). Selective Laser Sintering (SLS) is used to make models, typically in metals or nylon (see answer to question 5.).
Fused filament deposition (FDM) and Fused filament fabrication (FFF), sometimes also called filament freeform fabrication, is a 3D printing process that uses a continuous filament of a thermoplastic material that prints layer upon layer.
Resin printing is the process of solidifying resin by exposing it to UV lasers (SLA) or, controlled exposure to UV light with the use of a LCD/LED screen (MSLA). The resin solidifies when exposed to the laser or UV light, building the 3D model layer by layer.
Selective laser sintering (SLS) is an additive manufacturing (AM) technique that uses a laser as the power source to sinter powdered material (typically nylon or polyamide, metal powder), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.
