About this product
Kings FGF800 is a large-format pellet extrusion 3D printer with an 800×600×800 mm build envelope. The system processes raw polymer granules — the same feedstock form as injection molding — at material costs 5–10× lower than equivalent filament. A 0.4–2 mm interchangeable nozzle range covers applications from high-resolution tooling prototypes to fast structural prints. An optional 450°C nozzle assembly unlocks PEEK, PEKK, and ULTEM at large-format scale.
Why engineers choose the FGF800
Four things production teams verify before committing to large-format FGF.
Pellet economics
Granulate 5–10× below filament cost for the same polymer — injection-molding feedstock off the open market, no vendor lock-in.
450°C high-temp option
PEEK, PEKK, and ULTEM at 800×600×800 mm scale — rare capability in this build-volume class.
0.4–2 mm interchangeable nozzles
Match deposition rate to the job — fine-resolution tooling masters or high-throughput structural fill.
Pneumatic auto-feed
Runout detection prevents mid-print failures on unattended multi-day production builds.

Unedited feedback from engineers running large-format FGF
★★★★★
We moved our thermoforming tooling from outsourced CNC to the FGF800. A 12 kg ABS+GF mold prints overnight and costs a fraction of machined aluminum.

★★★★★
Pellet feedstock was the whole point — we run the same PA+CF granulate as our injection molding line. No filament markup, no vendor lock-in.

Common questions
Don't see yours? Email [email protected] — NDA standard, typical reply within 4 hours.
What is the difference between FGF pellet printing and filament (FFF) printing?
The Kings FGF800 prints directly from plastic pellets — the same feedstock used in injection molding — instead of filament. Pellets cost a fraction of filament for the same base polymer and open access to grades that are never extruded into filament, including glass- and carbon-filled compounds. The integrated pneumatic feeder with runout detection keeps large builds running without spool changes. The trade-off: FGF is built for large-format speed, not fine detail. For jigs, tooling, and structural parts measured in kilograms, the Kings FGF800 economics are hard to match with filament.
What pellets can the Kings FGF800 process — can I run my own compound or regrind?
The Kings FGF800 is an open-material system: PLA, ABS, ASA, PETG, TPU, PC, PA, and PP, including fire-retardant grades and filled compounds such as ABS+GF, ABS+CF, ASA+GF, PETG+GF, PA+CF, and PC+CF. It accepts pellets 1–5 mm in diameter, which covers standard injection-molding granulate and most regrind. If you run a proprietary blend or recycled compound, our applications engineers will help you qualify it on the Kings FGF800 before you commit.
How much cheaper are pellets than filament?
For the same base polymer, pellets typically cost 5–10× less per kilogram than filament, because you skip the filament extrusion step entirely. On a Kings FGF800 printing multi-kilogram parts — a 10 kg layup tool or vacuum-forming mold — that difference is a line item, not a rounding error. There is also no filament vendor lock-in: you buy granulate on the open market. Ask us for a cost-per-part comparison against your current filament spend.
Can the Kings FGF800 print carbon-fiber or glass-fiber filled materials?
Yes. Fiber-filled compounds — ABS+GF, ABS+CF, ASA+GF, PETG+GF, PA+CF, PC+CF, and PEI+CF with the high-temperature option — are core applications for the Kings FGF800. Fiber-filled pellets are widely available as injection-molding granulate, while the same compounds in filament form are expensive or simply not offered. Hardened wear components in the extrusion path handle abrasive fibers; our engineers will recommend the right nozzle configuration for your compound.
Do pellets need drying before printing?
Yes — the same moisture rules as filament apply, and hygroscopic polymers (PA, PC, PETG) must be dried to the resin maker's spec before printing on the Kings FGF800. The hopper with integrated automatic pneumatic feeding is designed to work in line with a granulate dryer, the standard setup in injection-molding shops. We'll spec a drying workflow for your material as part of installation and training.
What surface finish and detail should I expect from large-format FGF?
Plan for visible layer lines and post-machining on mating surfaces — the Kings FGF800 is engineered for structural large-format parts, not consumer-grade cosmetics. Bead geometry depends on the nozzle installed; larger nozzles trade finish for throughput, and the 0.4–2 mm range lets you choose per application. Typical practice for tooling: print near-net shape, then machine critical faces. If your application needs fine detail under a millimeter, a filament or resin system is the better tool — we'll tell you honestly which.
What infrastructure does the Kings FGF800 require?
Single-phase 220 V AC power with 4.6 kW rated consumption, compressed air at 0.6 MPa, and floor space for a 200 kg machine with an 800×600×800 mm build platform plus material handling. The heated bed runs up to 120°C with PEI, aluminum, composite, or glass work surfaces; chamber heating is available as an option for high-shrinkage engineering polymers. Connectivity is SD, USB, and WiFi with STL, OBJ, AMF, 3MF, STP, and STEP support. We confirm site requirements before shipment as part of every Kings FGF800 installation.
What is included with every Kings FGF800 system?
Installation, operator training, and validated print profiles for your starting materials are included with the Kings FGF800, backed by a tailored warranty with same-week dispatch on critical issues. Lead time is 4–6 weeks, and your price is held for 7 days after order. Support comes from applications engineers who run large-format AM daily — response inside 24 hours.
