FDM
FDM or Fused Deposition Modeling 3D printers are 3D printers that use thermoplastic filaments as a material. In the working principle of FDM 3D printers, the thermoplastic filament is fed through a hot extruder where the plastic becomes soft enough to be fully inserted by the print head. The molten filament is then deposited layer by layer in the printing area to form the workpiece.

SLA
SLA, ie Stereolithography 3D printers, are 3D printers that use resin as a material. The light coming from the laser light source in the SLA 3D Printer cures the light-sensitive resin poured into the printing chamber of the printer by connecting the molecule chains of the resin, and the 3D model is formed by the curing of the resin.
Specifications;
·Sensitivity down to 50 micron +
·Smooth surface +
·Suitable for complex details and difficult models +
·High production cost -
·Low mechanic resistance and can be affected by UV lights -
Most used materials in FDM production
Polylactic Acid (PLA)
It can be called the most commonly used filament in 3D printers. The production process is easy. It is an environmentally friendly filament, biodegradable, known to be produced from corn starch or sugar cane.
Specifications;
·Hardness: High
·Flexibility: Low
·Resistance: Medium
·Insoluble
·Generally food compatible
Acrylonitrile butadiene styrene (ABS)
Compared to PLA, its mechanical properties are superior, but the production time is longer. This filament can withstand high physical strength and high temperatures.
Specifications;
·Hardness: High
·Flexibility: Medium
·Resistance: High
·Soluble in acetone
·Generally not food compatible.
PETG
It can be called a material between PLA and ABS. Its printing resistance to PLA is similar to ABS.
Specifications;
·Hardness: High
·Flexibility: Medium
·Resistance: High
·Insoluable
·Generally food compatible
PC(POLYCARBONATE)
Polycarbonate filaments can withstand up to 110 ° C and have very good physical strength. Although similar to Plexiglass, pc is a medium flexible material. It allows bending until it deforms. Due to its physical properties, it is ideal for parts that need to retain their strength, toughness and shape in high temperature environments such as mechanical, electrical or automotive parts. Thanks to its optical clarity, it can be used in lighting projects.
Specifications;
·Strength: Very high
·Flexibility: Medium
·Resistance: Very high
·Print temperature: 270 ° C – 310 ° C
·Shrinkage / warp: Noteworthy
·Insoluable: No
·Generally not food compatible
Flex Filament(TPE,TPU,TPC)
Thermoplastic elastomers are plastics with a rubber-like nature. TPE or TPU filaments are preferred if the part needs to be bent, extended or compressed. TPC filament, on the other hand, meets the same purposes, but is used in case of exposure to the sun outside.
Specifications;
·Hardness: Medium
·Flexibility: Very high
·Resistance: Very high
·Insoluable: No
·Food compatible: No
