Information about materials:

PLA

PLA is a biopolymer, which is produced from renewable sources such as corn starch or sugar cane. This makes it biodegradable under industrial conditions and prevents it from emitting unpleasant, toxic odors during printing.

  • Rigidity: A hard and rigid material that ensures good shape retention.
  • Easy to print: It melts at a lower temperature and has minimal shrinkage (thermal expansion), so the corners do not curl up and a heated bed is not necessary.
  • Aesthetics: It can be used to produce highly detailed prints in a wide range of colors and even with special effects (silk gloss, matte, wood or metal effect).

Disadvantages and limitations:

  • Flexibility: Although strong, it is not flexible. When subjected to a strong impact or tension, it breaks rather than bends.
  • Low heat resistance: That's it's biggest weakness. It already melts at 50-60°C making it unsuitable for cars (in the summer), or objects exposed to long term sunlight.

PETG

PETG is essentially the same material used to make soda bottles, but it is modified with glycol to make it less brittle and easier to print with.

Main advantages:

  • UV-Resistance: It tolerates direct sunlight better than PLA, making it more suitable for outdoor use.
  • Heat resistance: It retains its shape at temperatures of up to 75-80 °Cmaking it suitable for use in car accessories or light fixtures.
  • Mechanical toughness: It is not as rigid as PLA. It is more impact resistant and has minimal elasticity, so it tends to bend under load rather than break immediately.
  • Excellent layer adhesion: The layers bond extremely strongly to each other, resulting in more durable, robust components.
  • Chemical Resistance: Resistant to acids, alkalis, and water.

TPU

The main characteristic of TPU is its Shore hardness. This is a scale that shows how soft the material is. For example, 85A is like a shoe heel, while 95A-98A is like a harder skateboard wheel or a phone case.

Advantages:

  • Layer adhesion: Perhaps the material with the best layer adhesion; it is almost impossible to tear along the layers.
  • Flexibility and stretchability: It can withstand repeated bending without cracking or fatigue.
  • Impact absorption: It dampens vibrations and shocks well.
  • Abrasion resistance: It is very resistant to wear and tear, making it ideal for industrial rollers and protective covers.

PLA-CF és PLA-GF

The PLA-CF (Carbon Fiber) and PLA-GF (Glass Fiber) are composite materials in which traditional PLA is reinforced with chopped carbon fibers or glass fibers. These materials are not necessarily "stronger" (in terms of tensile strength), but they are much stiffer and more aesthetically professional.

PLA-CF (carbon fiber PLA) is the most popular choice when technical appearance and high rigidity are required, while PLA-GF is less common but an excellent alternative when durability is as important as rigidity.
