A 3D Printer is Not Always a Food Safe Producer The chemical composition of PETG also makes it easy to recycle and helps cut down on the single use plastic problem.Īs PETG has become a more popular option in food packaging, it is important to consider how food safe it really is. It is a common option for food packaging and containers, as well as reusable water bottles. Our food industry also uses a significant amount of PETG. So many products in the medical field require constant and intense sterilization, and PETG’s rigid structure make it a good choice. It is also a common material in the medical field, being used in packaging and medical implants. It helps to produce synthetic fibers, which are then used to make the clothes we wear. It is a common product used in high end manufacturing. The strength and chemical structure of PETG make it a very versatile material. Some brands are even modifying their PETG to better fit needs of the 3D printing community specifically, making the possibilities almost endless.Īnyone with access to a 3D printer can use PETG and is only limited by their creativity. Many aspects of PETG, such as its adhesive qualities and low shrinkage, also translate well into the 3D printing community.Īs 3D printers have become more popular among average consumers, the uses of PETG are expanding even more. When you compare this price to some substances, such as acrylic or polycarbonate, it is actually cost-effective to use PETG. Why would so many people use PETG when it is oftentimes the more expensive option? It is because the creation of PETG brings many benefits over those other options, even other plastic types. Having special additions to the PETG, such as carbon fiber reinforcement, can increase that price even more. You can expect to pay up to $40 for a spool of PETG, depending on which brand you choose, making it generally more expensive than alternative filaments like PLA. The benefits of PETG do come with a bit of a higher price tag. It is also very sticky, which does make it a little harder to work with, but also means the different pieces are very adhesive. It is easy to use and the strength and chemical resistance of PETG make it very moldable, giving manufacturers a lot of options. PETG is clearer than other filaments, although some brands do come in color. Adding the glycol to form PETG helps make the end product stronger and less brittle.įor anyone without a science background, PETG is essentially a very commonly used type of plastic, accounting for 18% of global plastic production worldwide. PET is a common thermoplastic polymer, but it is not ideal for many circumstances. It is made from adding glycol to the common polyester Polyethylene Terephthalate, or PET. PETG, sometimes spelled PET-G, is a substance called Polyethylene terephthalate glycol. This, along with it being fully recyclable, explains why it is already a common plastic for food containers. The fact PETG can be sterilized, as they do in the medical field, helps solidify it as food safe. You should always check the safety data sheet to get specifics about the brand you are using. PETG is generally considered a food safe material, and certain brands have received FDA approval. If a product cannot be properly cleaned, it can foster harmful bacteria growth. Ability to be cleaned is an often left out consideration.This is the idea behind not drinking out of plastic water bottle that was left outside on a hot day. Many items are stable at room temperature but tend to leach chemicals at higher temperatures. Temperature is another important consideration.The safety of an item, for example, straws, plates, or containers, that has prolonged contact with food, is more important than something that has minimal or accidental contact. Here are a few different aspects to consider when discussing if a material is food safe or not. If plastic or other materials contain chemicals that are bad for our health, they can transfer those hazardous chemicals to our food and eventually to our bodies. When different materials come into contact with each other, particles can migrate from one to the other, including on to the food we eat. Whether or not a material is food safe basically determines whether or not it can come into contact with food and not cause any adverse health effects.
