3D Printing With PEI Filament: What It Is, Best Properties, And How To Use It In 2020

3D Printing With PEI Filament

While the majority of innovative filament substances used during 3D printing concentrate on how they render the completed print appear, there is a few that prioritizes efficiency. These designs are ideal for 3D printing items that can be used in manufacturing environments or situations where malfunction is not even a choice, with excellent mechanical strength and good resilience. 3D Printing with PEI Filament is one of the best filaments to be used for 3D printing.

What is PEI Filament

PEI accounts for Polyether Imide, a polymer that Joseph Wirth of GE’s Plastic Division initially formed back in the very early 1980s. It is an undifferentiated plastic with a translucent amber hue that is distinctive. It is mostly used for its high tensile properties, stable electronic characteristics, and outstanding chemical inertness.

PEI, alongside PEEK (Polyether ether ketone), is among the plastics in the chemical group PAEK (polyaryletherketone). Because of their exceptional mechanical strength and flexibility in high-temperature environments, PAEK plastics are required. They are immune to chemical attacks and, when subjected to environmental conditions, don’t really decay. They are used for 3d printing with PEI filament. PAEK plastics are also a good alternative for 3D printing since, when processed, they don’t really emit poisonous gases.

It is possible that you will need an all-metal funnel that can withstand these extreme temperatures.

Best Settings For Working With PEI Filament

For working properly with this filament, you need proper PEI 3D Printing temperature. You also need to check if your 3D printer is capable of handling the PEI filament. It also has to be necessary for your printing bed to achieve levels above what any other 3D printers can deliver.

Finally, you ought to provide a decent insulation that holds the printing region above 90 ° C. Usually, this is not something you would “repurpose” to a current 3D printer, since it is therefore important to build the electronic systems to survive those levels. These things are required for 3d printing with PEI filament. Some other things that should be kept in mind are:

  • For PEI, the suggested printer nozzle temperature could be anywhere from 355 to 390 ° C. Based on the quality of the filament, the exact temperature ideal for your condition will vary. Starting at low temperatures and rising the temperature setting steadily will be better until just before you get into any trying to string issues.
  • When printing with PEI, a heated print sheet is required to prevent issues with spinning. For PEI, the optimal bed temperature is somewhere within the 120 to 160 ° C range. Until you begin to print, mind to pre-heat the bed (along with the enclosure). For even more consistent warming and faster extraction of the finished paper, we consider to use a glass pad.
  • It will be better to apply a heat-stable glue on the print bed for added protection against spinning. A hairspray coating or Kapton tape should be appropriate. With just a glue stick, some consumers have had results, so if you don’t have the perfect options on hand, it might be worth a try.

It hardly bears noting, but during the entire PEI printing process, you will have no cooling fan triggered. Rather, an engineered print chamber framework is what you require. Once the print has also been completed, because of the significant drop in temperature, it is worth bearing in mind that the hot filament will compress by a massive margin. It could be a matter of experience to decide what the optimal moment is. This things should be kept in mind while 3d printing with PEI filament. Also, 3d printing PEI vs glass is done.

Pros And Cons Of PEI Filament

3d printing with PEI filament requires a lot of engineering. PEI 3d printing filament has characteristics of high performance but there are advantages and disadvantages of this filament.

Title
Pros
PEI puts to shame the power of most other 3D printing filaments, much like PEEK. PEI provides 85 MPa of strength properties and 3.2 GPa of Young’s modulus. A standard nylon filament has a mechanical properties of 34 MPa and a Young’s modulus of 0.6 GPa, to bring it into perspective.
Again, some filaments we usually refer to as “high-temperature,” such as ABS or nylon, are beaten out by thermal stability. PEI has a temperature range of 217 ° C for glass and tends to melt at 240 ° C. This renders PEI an exceptional substrate for practical modules who have to withstand a lot of pressure and surgical instruments which need to be constantly autoclaved.
Title
Cons
If you can buy a 1-kilogram spindle of the regular ABS or PLA filaments for less than $20, it can cost anything from $150 and $200 for a spindle of PEI filament of a comparable size. A further explanation why printing with PEI is so rare and something which is used only for the most economically important applications is this massive shift in quality.
The vast majority of commercially available PEI filament goods come from the ULTEM label and are merely renamed by the retailers. This suggests that all these filament materials have same characteristics and emerge from same resin. This supply restriction is not something that you would usually experience with other filaments and undoubtedly hinders the chance of playing with various forms of PEI filament.

Buying Guide

  • Proper resolution: The 3D printer that you are buying should have proper resolution. That is very much important for good quality printing.
  • Price: Price is also an important factor. A number of options are available in the market and they all fall within a great affordable range.
  • Know the thing before printing: Always make sure to have a clear idea about what you are printing. This is one of the biggest considerations of buying a 3D printer.
  • Good features: The printer that you will be buying should have proper features. There must be best as well as safety features available.

Frequently Asked Questions

Is it worth it to buy a 3d printer?

3D printing is great but for all it’s just not worth it. Most individuals waste a lot of money on 3D printers when just exporting a few pieces is really all they can do. Worse still, some people are buying a 3D printer just to figure out they don’t really like using it.

Which 3D printing process is popular?

Extrusion is the most popular 3D printing process also known as FDM for Fused Deposition Modeling or FFF for Fused Filament Fabrication. You can try the other process but this process is the best.

Do you need a heated bed 3D printer?

Heat beds are used because they dramatically improve print quality by keeping the extruded plastic warm and thus preventing warping. Warping is a common condition caused by plastic on the edges of the part cooling down at an uneven rate when compared to the plastic inside of the part.

Who created 3D printing?

Chuck Hull is the creator of 3D printing. The first 3D printer, which used the stereolithography technique, was created by Charles W. Hull in the mid-1980s.

What is 3D printing most commonly used for?

The 3D printing process is the best process to understand anything easily. For this reason, people use this technique in every industry, school, and office.3D printing is used to produce architectural scale models, enabling a faster turnaround of the scale model and increasing the overall speed and complexity of the objects produced. 

Conclusion

PEI filament helps to showcase the potential of proper 3D printing. 3D printing with pei filament has got its own advantages which are far superior than the normal printing. For proper 3d printing with pei filament, proper pei 3d printing temperature is required. Here, you can get more information about 3d printing with pei filament.
