3D printer filament PETG is new popular filament in town. Along with PLA and ABS, PETG is here to stay and for good reason. In this article we will explain what makes PETG filament so special and why this could be a filament for you.
We strive to provide quality filaments at an affordable price. Whethere it's PLA, ABS, PETG, FLEX, or WOOD, we strvie in engineering a consistent diameter and roundness that prevents nozzle extruder clogging.
The filament PETG is very similar to PET, which is the most commonly used plastic, the added material is “glycol-modified”. Like plastic is very durable, can be sterilized and impact resistance. You're probably getting a good idea on why this filament is gaining popularity in the 3D printing world. PETG's extrusion temperatuers vary between 230 and 265°C. Some of the advantage of using our PETG filaments for 3D printers include: printing an object that is flexible and durable, no need for post-treatment, good flowability from the extruder nozzle. The roundness range and high precision dimension range of our PETG 3D filaments ensure you produce a high quality 3D print time after time
1.75 mm if the actual extruder nozzle diameter used in a lot of 3D printers today. Smaller diameter filament tends to heat faster which in turn allows you to print faster. Smaller nozzles are more precise and flow control which reduces filament oozing. The flow rate is measured in mm's, your printer determines the amount of plastic that is extruded through the nozzle based on the extrusion speed. When you have an consistent diameter filament this will lead to an consistent extrusion. 3D filament is manufactured in masses, the variance or tolerance in the manufacturing process for diameter is a challenge. The filament diameter tolerance problems in manufacturing can cause big problems in the different components in your 3D printer. You could have extruder failures and filament will not make it to the hot end. The extruder motor can experience issues in the middle of the printing process if the 3D filament diameter changes. You can use a micrometer tool to measure the diameter to ensure it meets it's tolerance.
Spools & Storing Filament
When looking at 3D printing filament spools you want to look at this spool diameter and design. When 3D filament is manufactured, plastic pallets or melted and the filament goes through a cooling process before it is wound onto a spool. When using 3D filament during the printing process, you want the filament on the spool to be just between a little loose and not so tight because the filament needs to be fed through the extruder without a lot of tension. When buying 3D filament once ensure the packaging includes a packet of desiccant. Plastic over time can absorb moisture which can damage or filament or create bubbles especially in 1.75 mm as opposed to a thicker 3mm. So when you find yourself looking for 3d printer filament types, ensure you've done your homework before you hit the print button.
