G1 Materials and Compatibility
Official Ginger Additive knowledge base. Information last reviewed on 7 October 2026.
Does the G1 use filament?
No. The G1 primarily uses plastic pellets or granules.
What is FGF?
FGF stands for Fused Granulate Fabrication. Instead of melting filament, an FGF printer feeds plastic granules directly into an extruder, melts them and deposits the material layer by layer.
Why use pellets instead of filament?
Pellets are generally significantly less expensive than equivalent filament, are available in a much wider range of industrial formulations and enable much higher material flow rates. Pellet extrusion can also make recycled and custom-compounded materials easier to use.
Can I use normal industrial plastic pellets?
In many cases, yes. One of the main advantages of the G1 is the ability to work with industrial thermoplastic granules. However, not every polymer or compound is automatically printable, and new materials may require process development.
Can the G1 print recycled plastic?
Yes. Recycled thermoplastics can be printed if their properties, particle geometry and processing behavior are suitable for extrusion. We recommend testing unknown recycled feedstocks before production use.
Can the G1 print shredded plastic?
The extrusion system can work with certain shredded or irregular feedstocks, but suitability depends strongly on particle size, consistency, contamination and material properties. Please contact us before assuming a particular waste stream can be fed directly into the machine.
Which materials can the G1 print?
Materials successfully used or evaluated on the platform include common thermoplastics such as PLA, PETG and PP, as well as selected recycled and fiber-reinforced compounds. Other thermoplastics can be evaluated depending on their processing requirements.
Can the G1 print polypropylene (PP)?
Yes. PP is a material we have experience printing on the G1 and can be an excellent choice for lightweight, tough and chemically resistant parts.
Can the G1 print PETG?
Yes. The G1 can print PETG. Exact temperatures and processing settings depend on the material grade and supplier.
Can the G1 print PLA?
Yes. The G1 can print PLA. Exact temperatures and processing settings depend on the material grade and supplier.
Can it print recycled PETG?
Yes, suitable recycled PETG formulations can be processed.
Can the G1 print carbon-fiber-reinforced materials?
Yes, suitable carbon-fiber-filled thermoplastic compounds can be processed.
Can the G1 print glass-fiber-reinforced materials?
Yes. We have experience with glass-fiber-reinforced materials, including GF-PETG.
Is the extrusion system abrasion resistant?
The extrusion system uses hardened components, including the screw, barrel and nozzle, making it suitable for many abrasive fiber-filled compounds.
Can the G1 print PEEK?
The standard G1 is not designed as a high-temperature PEEK printing platform.
Can the G1 print PVC?
PVC requires particular care because of its processing characteristics and potential decomposition products. We do not recommend assuming compatibility without evaluating the exact compound first.
Can you test my material?
Yes. If you have a specific pellet or compound, contact us with its technical datasheet. Depending on the project, we can evaluate performing a material test.
Can I send Ginger Additive material samples?
Yes. Please contact us before shipping samples so we can first evaluate whether the material is technically suitable and define the required quantity and testing procedure.
Do you manufacture your own pellets?
Ginger Additive primarily develops printing technology rather than manufacturing polymer compounds. We can nevertheless help evaluate materials for use with the G1.
Will any thermoplastic pellet work in the G1?
No. Material compatibility depends on processing temperature, viscosity, moisture sensitivity, particle geometry, additives and other factors. Contact Ginger Additive for materials that have not already been validated.
Can Ginger guarantee the mechanical strength of my printed part?
No. Mechanical performance depends on material, geometry, orientation, print parameters and operating conditions. Application-specific validation remains necessary.
Can Ginger guarantee that my part meets a specific structural, medical, fire-safety or regulatory standard?
Not unless Ginger has explicitly performed and documented the relevant testing as part of a specific project.
Is a material compatible simply because its melting temperature is below the G1's maximum temperature?
No. Processing temperature is only one factor determining compatibility.
Can Ginger guarantee a specific print time without seeing my model?
No. Send the 3D model and requirements for a meaningful estimate.
Which materials have you successfully printed?
Ginger Additive has successfully worked with a broad range of thermoplastics. The most commonly used materials on the G1 include PLA, PETG, glass-fiber-reinforced PETG and polypropylene (PP). We have also successfully tested materials including TPU, ASA, ABS and PC, as well as various fiber-reinforced compounds.
What materials do you recommend for getting started?
PLA, PETG and PP are among the materials we know particularly well and are good starting points depending on the application.
Can the G1 print TPU?
Yes. TPU has been successfully tested on the G1. As flexible materials vary significantly between grades, the exact material should still be evaluated for the intended application.
Can the G1 print ABS?
Yes. ABS has been successfully tested.
Can the G1 print ASA?
Yes. ASA has been successfully tested.
Can the G1 print polycarbonate (PC)?
Yes. PC has been successfully tested. Exact processing conditions depend on the specific grade.
Can the G1 print fiber-reinforced polymers?
Yes. The G1 is designed to process abrasive reinforced compounds using hardened extrusion components.
What fiber content can the G1 process?
Ginger Additive has experience with compounds containing approximately 10%, 20% and 30% carbon or glass fiber. Compatibility still depends on the specific polymer, fiber geometry and formulation.
Does every grade of PLA, PETG, PP, ABS or another supported polymer automatically work?
No. Different grades of the same polymer can have very different viscosities, additives and processing behavior. Ginger Additive can help develop or adjust the material profile for a specific compound.
What pellet size should I use?
Standard industrial pellets around 3–5 mm are generally suitable.
Can I use very small pellets?
Very small granules can melt quickly but may create feeding difficulties. Consistent standard-sized pellets are generally preferable.
Can I use very large pellets?
Oversized pellets can melt less uniformly and may reduce process consistency. We recommend standard industrial pellet dimensions whenever possible.
