FDM Manufacturing

PLA (Polylactic Acid)

Pros:
- Ease of Use:
  - PLA is one of the easiest materials to print with, requiring lower temperatures and minimal warping.
- Prototyping:
  - PLA is a fast, reliable material that is great for prototyping.
- Cost:
  - PLA is inexpensive.

Cons:
- Brittleness:
  - PLA is more brittle compared to other plastics, making it less suitable for functional parts.
- Heat Resistance:
  - PLA has a low melting point, making it unsuitable for high-temperature applications.

PLA Tough

Pros:
- Improved Strength:
  - PLA Tough offers better impact resistance and durability compared to standard PLA.
- Ease of Printing:
  - Retains the ease of printing associated with standard PLA.

Cons:
- Cost:
  - More expensive than standard PLA.
- Heat Resistance:
  - Still not suitable for high-temperature applications.

PETG (Polyethylene Terephthalate Glycol)

Pros:
- Strength and Durability:
  - PETG is stronger and more durable than PLA, with good impact resistance.
- Chemical Resistance:
  - PETG is resistant to many chemicals, making it suitable for a variety of environments.
- Ease of Printing:
  - PETG prints relatively easily with minimal warping.

Cons:
- Stringing:
  - PETG can be prone to stringing during printing.
- Cost:
  - More expensive than PLA.

ABS (Acrylonitrile Butadiene Styrene)

Pros:
- Strength and Durability:
  - ABS is strong and durable, suitable for functional parts and mechanical applications.
- Heat Resistance:
  - ABS has a higher melting point, making it suitable for higher temperature applications.
- Post-Processing:
  - ABS can be easily post-processed with acetone to achieve a smooth surface finish (Vapor Smoothing).

Cons:
- Printing Difficulty:
  - ABS can be challenging to print due to warping and the need for a heated bed and enclosed printing environment.
- Fumes:
  - ABS emits unpleasant fumes during printing, requiring proper ventilation.

ASA (Acrylonitrile Styrene Acrylate)

Pros:
- UV Resistance:
  - ASA is resistant to UV light, making it ideal for outdoor applications.
- Strength and Durability:
  - Similar to ABS in terms of strength and durability.
- Weather Resistance:
  - ASA is resistant to weather and environmental conditions.

Cons:
- Printing Difficulty:
  - ASA can be challenging to print due to warping and the need for a heated bed and enclosure.
- Cost:
  - ASA is typically more expensive than ABS.

Carbon Fiber Reinforced Filaments

Pros:
- Strength and Stiffness:
  - Carbon fiber reinforced filaments are extremely strong and stiff, ideal for high-strength applications.
- Lightweight:
  - Carbon fiber filaments are lightweight, offering high strength-to-weight ratios.
- Dimensional Stability:
  - These filaments have low shrinkage and warping, resulting in accurate prints.

Cons:
- Cost:
  - Carbon fiber filaments are more expensive than standard filaments.
- Abrasiveness:
  - The carbon fibers can wear down nozzles, requiring hardened steel or specialty nozzles.
- Brittleness:
  - While strong, carbon fiber filaments can be brittle, making them less suitable for parts subject to impact or bending.
