Formfutura EasyFil™ HIPS Grey is a stunning deep iron grey coloured and 100% opaque filament. 3D printed objects in EasyFil™ HIPS Grey will have a masculine and matt robotic iron-like appearance.

EasyFil™ HIPS will be a true competitor for mass mainstream 3D printing materials, such as PLA and ABS. With EasyFil™ HIPS being positioned as a new mainstream 3D printer filament, it will now bring a special 3D print material to the ordinary. You will now be able to print PolyStyrene objects just as easy as PLA, or ABS objects!

EasyFil™ HIPS is a is thermoplastic polymer filament known as High Impact PolyStyrene, which is especially designed for 3D printing PolyStyrene objects. EasyFil™ HIPS distinguishes itself from “normal” HIPS filaments by being slightly softer and more flexible – in combination with very limited warping, having an excellent thermal stability and 3D print flowing behaviour – resulting in a truly “easy to print” HIPS 3D printer filament and a true asset to our EasyFil™ filament range. 
With EasyFil™ HIPS you will be able to 3D print PolyStyrene objects with fine detail in a beautiful matt coloured finish.

EasyFil™ HIPS 3D printed parts are very lightweight and can very easily be glued together  with a variety of adhesives, such as HIPS styrene glues, epoxy based adhesives, superglues and also with contact adhesives. These specific characteristics of EasyFil™ HIPS, make our EasyFil™ HIPS an ideal filament for applications like model building, or for gluing modular prints. 

PolyStyrene is a thermoplastic which is very chemically inert, being resistant to acids and bases. Because of its resilience and inertness, PolyStyrene is one of the most widely used thermoplastic polymers in the world. PolyStyrene is for instance extensively being used in the food packaging industry, but also for the production of e.g. disposable plastic cutlery/dinnerware and CD/DVD jewel cases.

EasyFil™ HIPS has outstanding characteristics with respect to hygiene, strength and heat resistance and it prints really smoothly. 3D printed objects with EasyFil™ HIPS can be sanded, primed and if needed painted with acrylic afterwards. By giving your EasyFil™ HIPS printed object an acetone vapor smoothing treatment you will be able to create a really smooth and shiny surface. Your FFF/FDM 3D printed object will almost look like an injection moulded model.

EasyFil™ HIPS is available in various vivid colours and prints best at approximately 235°C. It is recommended to set your heated print bed temperature at approximately 90-110°C.
EasyFil™ HIPS has an excellent roundness and very tight diameter tolerances, which makes this filament a perfect match with all common desktop 3D printers. Printing with EasyFil™ HIPS 3D printer filament will go very smoothly with basically all FFF/FDM technology based desktop 3D printers, such as:

• Ultimaker
• RepRap (Mendel, Huxley, Prusa)
• Solidoodle
• MakerBot (Replicator, Replicator 2, Replicator 2X)
• Leapfrog
• UP! Plus, Up! Mini

Our EasyFil™ HIPS does not contain any hazourdas, or chemical substances. In fact, all our EasyFil™ HIPS filaments are RoHS certified and REACH compliant.

General Tips & Tricks for printing with EasyFil™ HIPS filament

  • It is recommended to have your print bed temperature set to approximately 90-110°C when printing with EasyFil™ HIPS. You may have to adjust the temperature settings of your print bed slightly based on your type of printer.
  • Do not remove the print from the build platform until the object is cooled/hardened (as HIPS remains pliable when heat bed is still hot).
  • A good first layer adhesion can be obtained on Kapton Tape, EuroCel Blue Masking Tape, PET Tape, and BuildTak™ plates.
