If a 3D printer is compared to a human body, filament can be compared to blood. Those using 3D printers should know what to look for while buying filaments for the printer. Visit this link http://aussie3d.com/ if you are also intersted in 3d printer in Sydney.
Reasons why a 3D Filament made of PLA plastic is preferred?
3D Printer Filament made from PLA plastic or polylactic acid is filament that contains renewable starches like sugarcane and corn. PLA does not emit much UFC or ultra fine particle and is biodegradable. These produce a subtle sugary and pleasant odor while extruding. Depending on color and specifications, extrusion temperatures can range between 160 degree and 220 degree Celsius.
Parts printed with the use of 3D Printer Filament made of PLA are rigid compared to parts printed by other kinds of plastic. Parts printed with the use of PLA generally have a slight glossy finish. PLA is less susceptible to warping during the printing process and is stickier than other kinds of plastic. PLA begins to turn malleable from around 60 degree Celsius. It requires a greater amount of force to be extruded as it has a high coefficient of friction compared to other plastic types. PLA is comparatively modern in FDM’s history and has a bright future.
Reasons why filament of a 3d printer made of ABS plastic is preferred?
Acrylonitrile Butadiene Styrene or ABS is a petroleum-based common thermoplastic. When a filament is made of ABS, good ventilation is advisable as ABS is more likely to produce ultra-fine particles. While extruding, ABS emits a subtle smell of burnt plastic. Depending on color and specifications, extrusion temperatures can range between 220 degree and 260 degree Celsius. Parts printed with the use of ABS are less brittle compared to PLA and have a bend. Parts printed with the use of ABS have a glossier look compared to PLA parts. ABS is more heat resistant than PLA and becomes malleable from around 100 degree Celsius. ABS requires less force to be extruded as it has a lower coefficient of friction compared to PLA. ABS had been used for 3D printing prior to PLA and is thus considered to be the filament with a legacy. These are the reasons why a filament of a 3d printer is made of ABS plastic is preferred.
It needs to be understood that the software that controls the printer calculates the extrusion volume on the basis of the diameter of the extruder nozzle, filament diameter, and the speed of extrusion (usually referred to as the “flow rate”), while printing with the use of any kind of FDM printer. The printer controls the volume of the plastic that is oozed out of the nozzle by pushing a particular length of filament down the heated end and turning the extruder wheel. If the diameter of the filament is irregular, the volume of the extruded plastic differs and the software would not and cannot make adjustments, thus causing inconsistent extrusion.
