About Torwell

Engineered in Our Own Factory Since 2011

Torwell Technologies Co., Ltd. was among the first high-tech companies in China dedicated exclusively to 3D printer filament R&D, manufacturing and export. More than a decade of extrusion know-how lets us solve the problems buyers actually face: diameter drift, bubbles, moisture, tangled winding and color mismatch between batches.

  • In-House R&D Formulation

    Our material team tunes resin, additives and pigments for print speed, toughness and surface finish.

  • 6 Automatic Production Lines

    Approx. 50,000–60,000 kg monthly output supports container orders and stable lead times.

  • Professional Testing Lab

    Diameter, roundness, tensile strength, melt flow and printability are checked for each batch.

  • Export-Ready Packaging

    Vacuum sealed with desiccant, carton-protected and labeled to your market requirements.

Quality Control

From Pellet to Spool: 5 Checkpoints Behind Every Roll

Print failures usually start in the factory. This is how we control the variables before the filament ever reaches your customer's printer.

  1. Raw Material Drying

    Virgin resin is dried to a controlled moisture level before extrusion to prevent bubbles and stringing.

  2. Precision Extrusion

    Temperature-profiled screws and cooling baths keep melt stable for a smooth, void-free strand.

  3. Laser Diameter Gauging

    Inline dual-axis laser measurement targets ±0.02 mm on 1.75 mm filament and flags ovality.

  4. Neat Auto-Winding

    Tension-controlled winding produces tangle-free layers that feed smoothly in AMS-type systems.

  5. Vacuum Packing

    Each spool is vacuum sealed with desiccant, labeled with batch data and boxed for long-distance freight.

Does Torwell offer OEM and private label 3D printer filament?

Yes. We support OEM and ODM projects including custom colors matched to Pantone or physical samples, private label spools, branded cartons, labels and vacuum bags, with technical data sheets prepared for your market.

What diameter tolerance does your filament have?

Standard 1.75 mm filament is produced with a target tolerance of ±0.02 mm, monitored by inline laser gauges during extrusion. 2.85 mm is also available for selected materials.

What is your monthly production capacity?

Our 2,500 m² factory runs 6 fully automatic production lines and a testing laboratory, with an output of approximately 50,000–60,000 kg per month — enough for repeat container orders.

How do you prevent moisture absorption during shipping?

Filament is dried before winding, then vacuum sealed with desiccant and packed in individual cartons, protecting hygroscopic materials such as PETG, TPU and PC during sea and air freight.

Which countries do you export to?

We have long-term customers in more than 75 countries and regions across North America, Europe, South America, the Middle East, Oceania and Asia.
