Both ABS and PLA filament are suitable for use in the MYNT3D professional 3D printing pen.
But before you start your next 3D pen project, you may want to understand the differences between the two in order to choose which is best for you and your project.
ABS is oil based, where PLA is plant based. One of the most noticeable differences is that ABS gives off a chemical odor, and therefore requires proper ventilation. Some users may also prefer to wear a mask.
PLA, which contains plant-based ingredients such as corn starch and sugar cane, is said to emit a sweet smell.
From an environment standpoint, ABS is recyclable. PLA is biodegradable.
If you are familiar with 3D printers, it's good to note that 3D printing pens use lower temperature setting for filament. It is recommended to set ABS at 210°C and PLA at 175°C.
And as with 3D printers, 3D printing pens can experience filament extruding after the feed button is released. This is more likely with PLA filament, and slightly decreasing the pen temperature can help.
ABS is stronger than PLA, which is more brittle. However, ABS is known to slightly warp and shrink.
ABS filament extrudes thicker, making projects faster to complete.
PLA filament is preferred by 3D pen users for wearable projects such as jewelry.
