VoluFab
Industry Solutions

Industrial FDM for six industries

Backed by 300+ real industrial customers of INLONG — from material selection to volume delivery, end to end.

50–90% total cost reduction
Design-to-part in 24–72h
50%+ lighter than aluminum

Humanoid Robotics

From prototypes to low-volume structural parts

Pain points
  • 20–30 molds per model — huge tooling cost
  • Frequent design iterations, expensive mold changes

Print shells, brackets and joint parts directly in carbon/glass-fiber FDM; topology-optimized lightweighting saves 20–40% material; annealing and carbon-wrap boost strength 2–5×.

Tooling cost −50~90%
Materials: PET-CF · PAHT-CF · PEEK · TPU

Case: full shell set for a leading humanoid robot maker, printed in PAHT-CF with painted finish.

Inspection Robots

Power, pipeline and hazardous inspection

Pain points
  • CNC shells are costly with poor material yield
  • High-voltage and humid environments demand tough materials

One-piece PET-CF shells up to 470mm; PPS-CF withstands 10kV and 200℃+; full surface finishing incl. screen printing and painting.

Cost −30%+ · 30 sets/month
Materials: PET-CF · PPA-CF · PPS-CF

Case: a power-inspection robot leader moved shells from CNC to FDM and now delivers 30 sets/month.

UAV & Drones

Balancing lightweighting and strength

Pain points
  • Weight vs strength conflict, thin walls deform
  • Low-volume molds uneconomical; spare parts discontinued

CF parts reach 120–180MPa (2–3× injection PA6), density 0.7–1.4 g/cm³ (50%+ lighter than aluminum), 0.5mm thin walls, hollow/honeycomb structures; design-to-part in 24–72h.

Spares at 1/3 of OEM cost · 48h delivery
Materials: PAHT-CF · PA6-CF · PET-CF · PPA-CF

Case: broken 2019 agri-drone frame restored via 3D scan + PA6-CF in 48h at ¥260 vs ¥800 OEM.

Rehabilitation & Medical

Custom orthotics and medical devices

Pain points
  • Off-the-shelf fit <30%; casts are 6× heavier, poorly ventilated
  • Hand casting takes 3–7 days; children need 3–4 refits yearly

PET-CF/TPU custom foot orthoses, knee braces and surgical guides; medical device housings cut part cost 50–80%; emergency tools in 24h.

Cost −50~80% · better fit
Materials: PET-CF · PAHT-CF · TPU

Case: long-term partner Zep Medical receives custom rehab parts printed in PAHT-CF/PET-CF.

Auto Modification

Custom low-volume and performance parts

Pain points
  • Hand-made metal/carbon parts cost $8,000+ and take 5–7 days
  • Complex surfaces need joining, losing 30% strength

PET-CF one-piece interior parts with embedded electronics slots (months → 1–2 weeks); PAHT-CF off-road bumpers with lattice infill cut 25% weight; PEEK throttle valves withstand 260℃ and chemicals.

Cost −65~70% · cycle −60%+ · weight −25–30%
Materials: PET-CF · PAHT-CF · PEEK

Case: 10+ interior parts for an EV brand; wind-tunnel aero parts cut from 7 to 3 days.

Off-Highway Vehicles

ATV · Golf carts · Sightseeing · Utility EVs

Pain points
  • Low volume, large shells — molding and CNC too costly/slow
  • High customization with strength plus finish

PAHT-CF ATV frames for strength and heat; PET-CF body shells for golf carts, sightseeing and utility EVs with painted finish.

No tooling · free-form styling
Materials: PAHT-CF · PET-CF

Case: multiple resort sightseeing and golf-cart body shells delivered.
