FGF material compounds

All Colossus systems work with granulates

Direct pellet extrusion means you can print with granulates directly instead of using filament. This means cheaper feedstock, a wider range of materials, mixing colors and the use of masterbatches directly in our print systems. Out of the many recycled and non-recycled materials that can be used with our print systems, a collection of material profiles have been pre-tested for optimal performance. Further materials are being developed as we are always looking to expand our material portfolio. Thanks to our close partnerships with many material manufacturers we are able to research and develop materials for specific client or market applications. Additionally we provide customer material testing when requested.

[foaming technique now available for FGF]

Our Revolutionary New Material!

LW PLA is now available in a stable compound for FGF printers, allowing you to print layer heights up to – and sometimes even over your nozzle size or print with low density and large weight reductions. Its your choice



PETg is a strong, high transparent material used often in 3D printing. Because it is easy to print with and has minimal shrinkage, this material is excellent for a large range of applications. Available in virgin, recycled grades and possible to order with added UV stabilizers.

(r)PETg is also available with fillings such as Glassfibre, Carbon fibre, stone powder and in a wide variety of colours both opaque and transparent. Ask us for the comounding options not listed on the website.


(r)PETg Carbon

PET-Carbon is a carbon fibre re-inforced PETg, making it a very strong material. With increased impact and heat resistance the material prints very easily. We use this material for a wide range of applications ranging from single line furniture to parts for the automotive industry. We love the recycled version, but can also provide this in combination with a virgin PETg. 

(r) PETg Carbon is only available in black due to the Carbon content. 

(r)PETg is also available with fillings such as Glassfibre, Carbon fibre, stone powder and in a wide variety of colours both opaque and transparent. Ask us for the compounding options not listed on the website.


(r)PETg Glassfibre

PET-Glassfibre is a fibre re-inforced PETg, relative to Carbon filled pet, this material is strong and versitile but unlike Carbon, Glassfibre PEtg can be coloured. This PET variant is also a strong material suitable for single line furniture and outdoor applications.  With increased impact resistance it adds a range of possibilities. The material prints very easily and is available in both virgin and recycled PETg grades. 

Available in pre-compounded colors or adjustable by masterbatch (depending on the recycling grade).


PP, rPP and PPL

PP is an allround material with amazing layer adhesion. Due to shrinkage, PP is normally filled with fibres to prevent warping. Colossus has multiple recycled PP versions as well as virgin ranging  from 0%-30% filled and we can help you print it while avoiding warping issues. Suitable for outdoor and food contact applications. 

r(PP) is also available in other filled options, such as hollow glass bubbles (3M tech) Ask us for the complete range and compounding options not listed on the website. 

post consumer PP

Consumer recycled PP

Special local recycled PP collected from Belgian households can be fully printable, without fibres. This material has more warping issues then other grades, therefore is not preferred to print without experience, but we can provide you with excellent quality prints with 100% pure recycled PP. This research also allows us to apply this to other PP recycling streams. 

Contact us to discuss the options. 


PE / PP Specials

PE and PE are  amazing materials in combination with different fillers such as Cellulose. Due to special partnerships within our recycling network we are able to provide you with special grades recycled paper and cellulose filled FGF printing materials. 

The range is available from 10% to 40% filled contents, delivering a wide range of visual appearances. 



PLA is commonly known as one of the easiest materials to print with. On top of this PLA is biodegradable and biocompatible because its made from renewable resources such as corn starch or sugarcane. PLA does not warp, making it Ideal for prototyoping and indoor applications.

(r)PLA is also available in different filled varieties and we use this as a base material for compounding with options such as wood, bronze, stone etc. 

PLA hemp

(r)PLA Specials

PLA can be compounded with different additives such as stone, wood or bronze. Our technology allows up to 50% filled PLA. PLAwood is for example very easy to work with. Depending on the temperature printed in can result in different colors. 

PLA bronze has properties, being very heavy it feels like bronze and even oxidizes when placed outside. PLA hemp is a compound with Hemp fibres, making it the most natural solution. Ranging from light to dark brown based on temperature and fill grades, there are not a lot of materials that give you this natural visual appearance. 



For all material types there is a wide range of masterbatches which can be added due to the direct pellet extrusion extruding systems. 

Our print technique provides possibilities of easy color layering within a design for example. By using a base material and adding color in masterbatch directly in the extruder, beautiful effects can be created without having to purchase large amounts of material in each color. 


Polycarbonate or Durabio

Polycarbonate is a strong and transparent material which can stand higher temperatures. Polycarbonate is often used in 3D printing when PET(g) properties, especially transparancy and/or higher impact resistance, is required, but the material needs to be stronger or UV resistant.  PC is very strong but best printed in a controlled environment. 

Durabio is a biobased PC, developed by MCPP, which provides the best option for a semi-bio polycarbonate, but it is not biodegradable. It can be used as a substitute for glass components. 



TPU and TPC are FGF printing materials with rubber like qualities. Having a material that is both flexible (to different degrees) and strong, while being able to withstand higher temperatures makes it a unique material for 3D printing.

Both TPU and TPC  have a wide variety of applications. Both materials are used in the manufacturing industry where rubber-like properties are required.


Compounding questions

If you have very specific material requirements needed for your project or process but no idea which material would be best suited? 

Or do you have a material that you wish to recycle in our streams or re-use for your own production?
