PEI (Polyetherimide) is a transparent, rigid polymer with outstanding chemical resistance, wear resistance, and high-temperature characteristics. It is an ideal material for applications that require machining, higher heat resistance, chemical resistance, and for non-critical applications in the medical industry. Similar materials include Ultem (POF), Nylon PA12, Nylon 6/6, Polycarbonate, and Acetal Copolymer. It is being used in applications such as Chemical resistant parts: Intended for blending circuits with acids or bases Delrin 3D Printing Marking Toolholder
A lot of people ask about Ultem 2300 as plastic for 3D printing. It is a very good material to work with and in fact, it is harder than 2.85 PLA and dissolves easier than ABS. But there are some things you need to keep in mind when using Ultem so I made a list of suggestions and recommendations in order to help you with the experience.
Plastic and Ultem 2300 are both great materials for 3D printing, but they have some differences. The most important difference is that Ultem 2300 is more durable plastic. This means that objects printed in Ultem are less likely to break during use than objects made of PEI.
PEI is a little softer and can be more flexible than Ultem 2300, though. It also has better thermal properties, becoming less brittle as it cools down.
PEI Ultem 1000 rod is softer and tends to warp less than Ultem 2300 does, so it’s a better option if you’re just starting to experiment with 3D printing and want something easy to use. It’s also easier to print at room temperature, which makes it easier to work with on hot days or in spaces where temperature control isn’t possible.
Ultem is a family of engineering plastics developed for use in demanding applications such as aerospace, defense, industrial equipment, and specialty vehicles. Ultem is engineered for high-temperature and/or high-impact performance. Ultem polyetherimide (PEI) resins are very high-temperature polymers used to create parts with excellent strength and durability.
There are some similarities between PEI plastic and Ultem 2300 material. The materials are both used in 3D printers, but they have different applications. Both of these materials can withstand extreme temperatures, but they have different melting points.
Ultem 2300 Material — This material has a higher heat deflection temperature than other materials. It is also stronger and more resistant to wear and tear than others on the market. Ultem 2300 is a high-performance resin that is similar to ABS, PLA, and PC. The material fumes are safe for people to breathe in, unlike many other filaments that use toxic materials. The filament can be used for parts that require high performance and strength in order to endure extreme temperatures.
Both PEI plastic and Ultem 2300 material have high resistance against acids, alkalis, and other chemicals so they can be used as an alternative to acid etching (for those who cannot use acid). It is also important to note that both solutions are soluble in aromatic hydrocarbons like chloroform, methylene chloride, or carbon tetrachloride. Considering Ultem 2300 is expensive, you need a supplier who can provide Ultem 2300 rod supplier service.
How to do machining
Machining PEI on a lathe is pretty straightforward. It’s not that dissimilar to machining polycarbonate or acrylic, in fact. Here are the basics.
If you don’t have your own CNC machines, you may need to outsource the PEI Ultem machining. Don’t sweat it – as long as you’ve done your research and picked a reputable shop, there’s no reason to stress. Here are eight tips for working with a shop that will make the process easier for you.
Trial Run: If possible, try having the shop do a trial run of the part you want to be machined. It’s a good way to make sure that you’re both on the same page and that the parameters you’ve given them will result in a part that fits your needs.
Expectations: Be sure to be clear about what materials and processes will be used to manufacture your prototype so they can give you an accurate quote. If they’re not confident about their abilities, it’s better to find out sooner rather than later. The last thing you want is for them to tell you “no problem” and then find out later that it actually is a problem.
Clear Communication: You may need to work through some iterations before things are just right – everyone does. Just be sure that everyone involved is on the same page about what is being changed and why.
