PETG is a Glycol Modified version of Polyethylene Terephthalate (PET), which is commonly used to manufacture water bottles. It is a semi-rigid material with good impact resistance, but it has a slightly softer surface which makes it prone to wear. The material also benefits from great thermal characteristics, allowing the plastic to cool efficiently with almost negligible warpage. There are several variations of this material in the market including PETG, PETE, and PETT. The tips in this article will apply to all of these PET-based filaments.

Polylactic Acid, commonly known as PLA, is one of the most popular materials used in desktop 3D printing. It is the default filament of choice for most extrusion-based 3D printers because it can be printed at a low temperature and does not require a heated bed. PLA is a great first material to use as you are learning about 3D printing because it is easy to print, very inexpensive, and creates parts that can be used for a wide variety of applications. It is also one of the most environmentally friendly filaments on the market today. Derived from crops such as corn and sugarcane, PLA is renewable and most importantly biodegradable. As a bonus, this also allows the plastic to give off a sweet aroma during printing.

ABS (Acrylonitrile Butadiene Styrene) has a long history in the 3D printing world. This material was one of the first plastics to be used with industrial 3D printers. Many years later, ABS is still a very popular material thanks to its low cost and good mechanical properties. ABS is known for its toughness and impact resistance, allowing you to print durable parts that will hold up to extra usage and wear. LEGO building blocks are made from this material for that same reason! ABS also has a higher glass transition temperature, which means the material can withstand much higher temperatures before it begins to deform. This makes ABS a great choice for outdoor or high temperature applications. When printing with ABS, be sure to use an open space with good ventilation, as the material tends to have a slight odor. ABS also tends to contract quite a bit as it cools, so controlling the temperature of your build volume and the part inside can have major benefits.

Flexible filaments are made of Thermoplastic Elastomers (TPE) which are a blend of hard plastic and rubber. As the name suggests, this material is elastic in nature allowing the plastic to be stretched and flexed easily. There are several types of TPE, with Thermoplastic polyurethane (TPU) being the most commonly used among 3D printing filaments. In many cases, these terms are used interchangeably, along with popular brand names such as Ninjaflex. The degree of elasticity in the plastic depends on the type of TPE and the chemical formulation used by the manufacturer. For example, some filaments can be partially flexible like a car tire but others can be elastic and fully flexible like a rubber band. This guide will cover tips to help you with both of these variations of flexible filaments.

Nylon (a.k.a. Polyamide) is a popular material in the plastics industry, known for its toughness and flexibility. Nylon filaments typically require extruder temperatures near 250 ºC, however, some brands allow printing at temperatures as low as 220 ºC due to their chemical composition. Many printers do not include a hotend that can safely reach 250 ºC, so these lower-temperature versions can be useful and potentially save you from needing to upgrade your hotend. One big challenge with Nylon filaments is that they are hygroscopic, which means they readily absorb moisture from their surroundings. Printing Nylon after it has absorbed moisture will lead to several print quality issues, thus filament storage becomes very important and requires special attention.
