FDM for 3D printing
Driving factors for FDM3D market and
application a. Open-source software lowers
technical barrier and opens the door for more
companies/individuals to play, from software
optimization and new software development to
innovative structural design and applications
b. 3D printer price drop mature technology,
more competition

• c. Printing materials wider selections and
  lower cost of different materials
• d. Consumer market - cost effectiveness attracts
  more individual consumers
• e. Government funding supports 3D printing in
  different countries.

PLA in 3D printing
What's PLA?
Poly(lactic acid) or polylactide (PLA) is a
thermoplastic aliphatic polyester derived from
renewable resources. Due to its wide applications
and environmentally friendly nature, PLA is
regarded as one new industrial revolution in
Polymers.

• From renewable resources, such as
• Corn starch (in the United States)
• Tapioca roots, chips or starch (mostly in Asia)
• Sugarcane (in the rest of the world)

15
PLA in 3D printing
Low shrink rate

• Advantages
• Non harmful, non-toxic, biodegradable,
  environmental friendly
• Excellent mechanical strength, good rigidness,
  suitable for complex models.
• Low material shrinkage rate
• Uniform diameter and no warp.
• Printing temperature is 190220?, lower than
  other materials.

Environmentally Friendly
Biocompatibility
Bio-based
Transparent/ Translucent

PLA Modifications

• Improvements and modifications to existing PLA
  material from eSUN for better performance and
  reliability through the following
• Control Melt Flow Index.
• Match crystallization and rapid prototype
  technology.
• Improve Impact Strength.
• Improve temperature resistance.
• Lifetime study on PLA.
• Functional optimization.

PLA Modifications
Presence of rigid particles help reduce the shift
between material clamping tooth
GOAL Increase friction between clamping tooth,
reduce relative shift and ensure stable material
feeding RESULT Improved printing precision,
size stability and warp resistance.

Improvement of PLA printing fluency

• Material fluency cannot be too fast or too slow,
  it must match the printing speed. This ensures
  that printing precision is maintained and not
  degraded.
• Material fluency is closely related to PLA
  melting speed, where Esun employs the following
  factors to ensure optimal PLA melting speed
• Adjust PLA molecular weight and distribution when
  synthesizing PLA.
• Further addition of molecular weight ingredient
  to control PLA melting speed.
• Adopt composite lubrication system to control PLA
  melting speed.
• Adopt sheet structure and fiber material to
  adjust PLA melting speed.

25
PLA Modifications

• PLA Lifetime adjustment

1. Method adopted Generation of various compounds
   to adjust PLA lifetime
2. Current compounds tested PLA/PHA, PLA/PCL,
   PLA/PBS, PLA/PPC, PLA/PBC, PLA/PEG by melting
   mix, and printing body organs via FDM technology
   for medical application.
