Composition of PETG Filament Properties of PETG Filament Comparing PETG with Other Filaments Limitations of 3D Printing with PETG Why PETG is Used in 3D Printing How to Use PETG in 3D Printing Best Configuration Settings for PETG 3D Printing PETG Filament: Print Speed and Melting Temperature Conclusion 1. What is PETG Filament? PETG, short for Polyethylene Terephthalate Glycol, is a synthetic thermoplastic polyester that is widely used as a filament in 3D printing, especially in Fused Deposition Modeling (FDM) printers. It is an adaptation of PET (Polyethylene Terephthalate), where the ethylene glycol in PET is partially replaced with cyclohexanedimethanol (CHDM). This modification enhances the properties of PETG, making it stronger, more durable, and easier to print compared to PET. 2. Composition of PETG Filament The composition of PETG filament is derived from polyethylene terephthalate (PET). PETG and PET have similar chemic...

Building a Powerful and Lightweight RC Battery Pack with 18650 Cells

Image
Introduction Hey there, fellow RC enthusiasts! Today, I'm thrilled to share with you an exciting project: building a 3 cell battery pack for your remote-controlled aircraft using 18650 cells. This inexpensive yet powerful and lightweight battery pack will take your RC models to new heights. So, let's dive in and get started! Be Cautious: Safety First! Before we jump into the nitty-gritty of building our battery pack, it's crucial to address safety concerns. Lithium batteries, including 18650 cells, can be hazardous if mishandled. They have the potential to cause fires, burns, and even explosions. So, it's essential to handle them with care. Never allow the open terminals of the battery pack to touch each other, and avoid exposing the pack to any mechanical damage. If you're not confident in handling lithium batteries, it's best to avoid attempting this project for your safety. Gathering the Materials To build our battery pack, we'll need a few key components...
