Pain points and material advice

  • Filament users

    Print failures
    Clogs, stringing, warping and filament breaks waste time and material. Advice: Choose filament with a stable diameter and controlled moisture content. Dry PA, PETG and TPU before printing.
    Diameter and winding
    Diameter variation causes uneven extrusion; untidy winding jams multi-color feeders. Advice: Check the diameter tolerance and that the winding is neat. GREENPOLYMER design target: ±0.03 mm. Typical values. Refer to the actual TDS.
    Functional parts not strong enough
    Functional parts printed in appearance filaments break or deform under heat easily. Advice: Choose engineering filament by service temperature and load, such as PC/ABS or carbon-fiber-reinforced PA6.
    High-speed printing
    Advice: Use high-speed PLA on high-speed printers and adjust the nozzle temperature to the label settings.

  • Printer makers

    Higher chamber temperatures
    Enclosed printers get hot inside when printing ABS, ASA and similar materials, and standard ABS housings may deform. Advice: Use heat-resistant PC/ABS for housings and reinforced PA for brackets near heat sources.
    Moving parts must be light and stable
    Advice: Carbon-fiber-reinforced PA6 has high specific stiffness and suits carriages and print head housings. Note that carbon fiber materials may conduct electricity.
    Safety around the power supply and heated bed
    Advice: Use halogen-free flame-retardant PC/ABS or PC for power supply compartments and wiring covers, and confirm V-0 at the actual wall thickness.
    Appearance and brand colors
    Advice: Color matching at the compounding stage keeps color more stable from batch to batch; high-gloss appearance parts can use mold-in-color materials.

GREENPOLYMER serves the 3D printing industry in two ways. First, we make filaments and resins. Second, we make engineering compounds for printer housings, structural parts and functional parts. This page also covers how other industries use 3D printing.

  • Domestic output keeps growing

    According to the National Bureau of Statistics, China produced 5.211 million 3D printing devices in 2025, up 52.5 % on the previous year.

  • Chinese companies lead in desktop printers

    According to CCTV's Xinwen Lianbo, Chinese companies hold about 90 % of the global market for consumer 3D printers. Users are not only hobbyists but also designers, engineers, schools and small print farms.

  • Printers are upgrading

    Many new printers are moving from open frames to enclosed chambers, high-speed motion systems and automatic multi-color feeding. With higher print speeds and chamber temperatures, the printers' own housings, print heads and bed brackets need materials that are more heat-resistant, lighter and more stable.

  • Filament is moving from "easy to print" to "fit for use"

    PLA is still a common mainstream filament, and PETG, ABS, ASA, PC and fiber-reinforced nylon are used more and more. Typical industry practice is to use printed parts as jigs and fixtures, spare parts and low-volume end-use parts.

  • Multi-color and high speed bring new filament requirements

    Multi-color printing changes material often, so diameter consistency, winding quality and spool dimensions matter more. High-speed printing needs the material to flow steadily at higher extrusion rates.

  • Packaging and traceability

    ISO/ASTM 52903-1 requires each batch of feedstock to come with information such as the supplier name, material designation and batch number. Filament with a specified maximum moisture content must be sealed and supplied with storage advice. Recycled filament and recyclable spools are also getting attention.

  • China output, National Bureau of Statistics: in 2025, China produced 5.211 million 3D printing devices, up 52.5 %.
  • Printer parts now need more heat resistance, lower weight and better stability.
  • PLA is still a common filament. PETG, ABS, ASA, PC and fiber-reinforced nylon are used more and more.
  • Multi-color and high-speed printing need tight diameter control, good winding and stable flow.

Notes

  • Flame ratings of pellets do not apply to filaments or printed parts. Test printed specimens separately.
  • Printed part properties depend on build orientation, layer height and infill. Z-direction strength is usually much lower.
  • Particle and VOC emissions from printing can be assessed with methods such as UL 2904, ISO 27548:2024 and GB/T 47564-2026, which takes effect on 2026-11-01. These are test methods and set no emission limits.
  • Filament standards: GB/T 42620-2023 covers ABS filament for material extrusion. GB/T 37643-2019 covers PLA filament for fused deposition modeling and is under revision. ISO/ASTM 52903-1 covers plastic feedstock for material extrusion. The terminology standard GB/T 35351-2025 is a non-equivalent adoption of ISO/ASTM 52900:2021.

Restricted substances and food contact

  • Restricted substances: 3D printers are electrical and electronic products and fall under China's GB 26572-2025, effective 2027-08-01, and the EU RoHS Directive 2011/65/EU. Filament itself is not an electrical product, but printer makers often ask material suppliers for substance information. Under Article 33 of EU REACH, a supplier of an article containing a Candidate List substance above 0.1 % must pass on information for safe use.
  • Food contact: printed parts for food contact must be assessed against GB 4806.1, GB 4806.7-2023, EU Regulation No 10/2011 or US 21 CFR Part 177, as applicable. GREENPOLYMER can support compliance testing to GB 4806 and EU No 10/2011; materials are discussed per project. PC materials are not used for EU food-contact parts.
  • Material information is available on request. Test reports and declarations for RoHS, REACH and food contact: to be verified by GREENPOLYMER.

  • Typical values. Refer to the actual TDS. Nylon absorbs moisture; conditioned strength and modulus are lower than the dry values.
  • Transparent PC (GRN-PC-L110), copolymer POM (GRN-POM-G110) and halogen-free flame-retardant glass-fiber-reinforced PA66 (GRN-PA66-E510) already have pellet grades. For other materials (PPA, lubricated PA66 and so on), GREENPOLYMER can do custom compounding to the part requirements. For compounding capabilities and the development process, see the FAQ and From compounding to filament; for pellet grades, see Products. PPS, PEEK and PEKK are planned.
  • For more engineering plastic applications, see the New energy storage industry page (material selection for flame retardancy, CTI and insulating parts).

Why GREENPOLYMER

  • Filaments and compounds

    One supplier provides both filament and compounded engineering plastics for printer parts.

  • Custom compounding

    Reinforcing, toughening, filling and blending. Formulations can be adjusted for heat resistance, stiffness, flame retardancy and appearance, and the same formulation can be made as pellets and as filament.

In-house tests are for development and quality control and do not replace third-party test reports or UL certification.

Industry FAQ

Q1. Should I use ABS or PC/ABS for printer housings?

ABS is usually enough for open-frame printers. Enclosed printers get hot when printing high-temperature filaments. Use heat-resistant PC/ABS for better heat and impact performance. Use halogen-free FR PC/ABS or FR PC near the power supply.

Q2. If the pellets are V-0, are printed parts from the same compound also V-0?

Not necessarily. Printed parts have layer interfaces and voids. They burn differently from molded parts. Test printed specimens separately.

Q3. What should I know before printing carbon-fiber PA6 filament?

Nylon absorbs moisture quickly. Dry it before printing and feed it from a dry box. Carbon fiber wears brass nozzles, so use a hardened steel nozzle. Printed parts may conduct electricity. Do not use them as insulators.

Q4. Can you make OEM / ODM filament for our brand?

Yes. GREENPOLYMER supplies OEM/ODM filaments for mainstream 3D printing brands. We can customize the formula, color, diameter, spool weight, labels and packaging. See the FAQ for MOQ.

Q5. Which filament suits jigs and fixtures?

Use carbon-fiber PA6 or carbon-fiber PETG for stiffness and dimensional stability. Use PC/ABS for heat and impact resistance. Use PA12-CF for lower moisture uptake. For ESD-safe fixtures, contact us about a custom filament.
