Definition

[/av_cell][av_cell col_style=’avia-center-col’]PLA, which stands for Polylactic Acid, is a type of thermoplastic made from plant starch[/av_cell][av_cell col_style=’avia-center-col’]ABS, which stands for Acrylonitrile Butadiene Styrene, is a petroleum-based thermoplastic[/av_cell][/av_row]
[av_row row_style=”][av_cell col_style=’avia-center-col’]

Warping

[/av_cell][av_cell col_style=’avia-center-col’]Less prone to warping as it cools quicker and is printed at a lower temperature[/av_cell][av_cell col_style=’avia-center-col’]More prone to warping as takes longer to cool and is printed at a higher temperature[/av_cell][/av_row]
[av_row row_style=”][av_cell col_style=’avia-center-col’]

Heated Bed?

[/av_cell][av_cell col_style=’avia-center-col’]It is not completely necessary to print with a heated bed however if you do have one it will help ensure the print stays firmly stuck down when printing and gives a glossy finish at the bottom[/av_cell][av_cell col_style=’avia-center-col’]You will find it very hard to print without a heated bed as the print will immediately start peeling up at the edges, heated perforated plates are particularly good for printing with ABS[/av_cell][/av_row]
[av_row row_style=”][av_cell col_style=’avia-center-col’]

Odour / Fumes

[/av_cell][av_cell col_style=’avia-center-col’]Does not smell at all and no room ventilation is necessary[/av_cell][av_cell col_style=’avia-center-col’]Can smell a little and can be slightly toxic so it is important to have a small amount of ventilation[/av_cell][/av_row]
[av_row row_style=”][av_cell col_style=’avia-center-col’]

Strength

[/av_cell][av_cell col_style=’avia-center-col’]Similar strength however PLA can be brittle when it does reach the limit[/av_cell][av_cell col_style=’avia-center-col’]Similar strength however ABS is less brittle and will bend slightly before breaking completely making it better at withstanding vibrations[/av_cell][/av_row]
[av_row row_style=”][av_cell col_style=’avia-center-col’]

Moisture

[/av_cell][av_cell col_style=’avia-center-col’]Is biodegradable so does degrade when in contact with moisture[/av_cell][av_cell col_style=’avia-center-col’]Does not react with moisture[/av_cell][/av_row]
[av_row row_style=”][av_cell col_style=’avia-center-col’]

Food Contact

[/av_cell][av_cell col_style=’avia-center-col’]Is suitable for food contact[/av_cell][av_cell col_style=’avia-center-col’]Is not suitable for food contact[/av_cell][/av_row]
[av_row row_style=”][av_cell col_style=’avia-center-col’]

Heat Resistance

[/av_cell][av_cell col_style=’avia-center-col’]Less heat resistant[/av_cell][av_cell col_style=’avia-center-col’]More heat resistant[/av_cell][/av_row]
[av_row row_style=”][av_cell col_style=’avia-center-col’]

Typical Print Temperature

[/av_cell][av_cell col_style=’avia-center-col’]210°C [/av_cell][av_cell col_style=’avia-center-col’]240°C [/av_cell][/av_row]
