Description:

PLA plastic – polylactic acid (PLA) is a biodegradable, biocompatible, thermoplastic, aliphatic polyester, which monomer is lactic acid.

Raw material for production is annually renewable resources such as corn and sugar cane.

 


Properties:

the melting point 173-178 °C

softening temperature – 50 °C,

– hardness (Rockwell) – R70-R90,

elongation at break of 3.8%,

– Flexural strength – 55,3 MPa,

tensile strength is 57.8 MPa,

modulus of elasticity in tension is 3.3 GPA,

modulus of elasticity in bending and 2.3 GPA,

– the temperature of the glass transition – 60-65 °C,

density of 1.23-1.25 g/cm3,

– minimum wall thickness – 1 mm

the accuracy of printing is ± 0.1%,

– the size of the smallest details – 0.3 mm,

shrinkage in the product – no;

– water absorption – 0,5-50%.

 

Advantages:

non – toxic,

wide color palette

– when printing, no need for a heated platform,

the dimensions of the stable,

– ideal for moving parts and mechanical models

excellent sliding of the parts,

– energy savings due to low-temperature softening of the filament,

there is no need to apply Kapton for brushing the surface to build the prototype

– the smoothness of the surface of the printed product,

a more detailed, completely ready to use objects.

 

Application:

as environmentally friendly products with a short lifespan (biodegradable food packaging, disposable tableware, packages, different packaging),

personal hygiene,

in medicine, for the production of surgical sutures and pins

3D printers as a source material for printing.
