Polycarbonate Filament: Everything You Need to Know
The strength, durability, and heat resistance of polycarbonate filament make it an adaptable material for 3D printing. Because of its hygroscopicity, polycarbonate filament readily absorbs moisture from its environment. When you open a polycarbonate product, be sure to keep it in a sealed, dry container. From basic characteristics to printing advice and post-processing processes, this thorough guide will cover all you need to know about polycarbonate filament.
What Is Polycarbonate Filament?
A thermoplastic polymer, polycarbonate filament, is a popular choice for 3D printing. It is an impact-and-wear-resistant member of the engineering plastics family. The process of making polycarbonate filaments for 3D printers involves melting and extruding the resin into thin strands. These strands are subsequently coiled onto spools.
Properties of Polycarbonate Filament
The versatility and exceptional quality of polycarbonate filament are due to its many useful characteristics, such as:
-Strength: Polycarbonate filament is ideal for printing long-lasting prototypes and parts because of its extraordinary strength.
-Heat Resistance: Because of its high glass transition temperature (Tg), polycarbonate filament is ideal for uses that require resilience to high temperatures without melting or deforming.
-Transparency: Printing thin layers of polycarbonate filament allows for the construction of clear or translucent objects due to the filament's transparency.
-Impact Resistance: The high impact resistance of polycarbonate filament makes it an ideal material for components that must endure abrupt pressures or shocks.
-Chemical Resistance: Because of its resistance to a wide range of chemicals, polycarbonate filament finds widespread use in industries that regularly deal with solvents and other potentially damaging compounds.
The Printing Procedure Using Polycarbonate Filament
Compared to printing with other materials, printing with polycarbonate filament does require a few changes. To print successfully, consider the following:
-Printer Temperature: The printing temperature of polycarbonate filament is high, usually ranging from 250°C to 300°C (though this varies by brand and formulation).
-Bed Temperature: For printing with polycarbonate filament, it is crucial to use a hot build plate. For optimal adhesion and minimal warping, set the bed temperature to around 90°C to 110°C.
-Enclosure: To avoid warping or cracking, it is best to print with polycarbonate filament in an enclosed chamber that maintains a constant temperature.
-Print Speed: To avoid stringing and maintain good layer adhesion, polycarbonate filament, which has a high melting point, is best printed at slower speeds.
-Cooling: Polycarbonate, in contrast to other filaments, does not necessitate cooling when printing. If you want to avoid warping and quick cooling, you should probably switch off or at least reduce the speed of your cooling fans.
Post-Processing Methods and Procedures
You can enhance the look and functionality of your printed polycarbonate parts by using post-processing techniques:
-Smoothing and Sanding: If your printed pieces have any rough edges or flaws, sanding them down will assist. If you want a really flawless finish, polish it or use chemical smoothing afterward.
-Painting and Coating: You can paint or coat polycarbonate filament with a variety of finishes to make it look better or more resistant to chemicals and ultraviolet light
-Annealing: The process of annealing, in which polycarbonate printed components are heated to a certain temperature, can increase their strength and longevity by relieving internal stresses.
-Removing Support: Take care when removing any support structures so as not to harm the printed component. Remove the backing without damaging the component by carefully slicing it away using pliers or a hobby knife.
