PLA-35 / PLA-45
Product Description
Direct answer: This PLA filament extrusion line is designed for producers who want to manufacture standard or customized PLA 3D printer filament. PLA is widely used for prototypes, education, models, packaging concepts, decorations and general-purpose FDM printing. When a biodegradable product claim is required, the material grade, additives, certification and end-of-life conditions should be confirmed before production.
Winsoar PLA filament extrusion line converts PLA raw material pellets and approved PLA compounds into consistent 1.75 mm, 2.85 mm or 3 mm filament for FDM and FFF printing. The line combines controlled drying, single-screw extrusion, precision die forming, staged cooling, online diameter measurement, servo haul-off and spool winding. Biodegradability depends on the PLA formulation and industrial composting conditions.
Standard PLA filament for desktop FDM and FFF printers
Colored PLA filament with masterbatch and controlled color changeover
Education, prototyping, model-making and general-purpose printing material
Special PLA compounds after screw, die, drying and cooling compatibility review
Prepare and dry the selected pellets according to the raw material supplier's moisture recommendation.
Melt, plasticize and homogenize the material in the single-screw extruder.
Form the filament through the selected die and establish the initial diameter.
Use staged cooling and sizing to control shrinkage, straightness and surface quality.
Measure diameter online and coordinate extrusion speed with haul-off speed.
Wind qualified filament onto spools with controlled tension for packing and shipment.
Moisture-controlled pellet preparation before extrusion
Stable single-screw plasticizing and metering for PLA raw material pellets
Interchangeable dies for 1.75 mm, 2.85 mm and 3 mm filament
Staged hot-water and cold-water cooling for straightness and dimensional stability
Online laser measurement with process tolerance confirmed against the buyer's standard
Servo haul-off and constant-tension winding for transport-ready spools
For a PLA project quotation, provide the material grade, additive or color formula, target diameter, tolerance, output, spool size, local voltage and whether biodegradable or compostability documentation is required.
For a complete multi-material configuration, see the 3D Printer Filament Production Line reference page.
Machine Configuration
The equipment is configured as a continuous filament process. The final screw, die, heating, cooling, laser, haul-off and winder selection depends on material, diameter, output, tolerance and spool requirements.
Main Technical Parameter
The following values are reference configurations for quotation. Final performance depends on material grade, formulation, die, process temperature, cooling conditions and quality standard.
| Item | SJ-35 | SJ-45 |
|---|---|---|
| Motor power | 5.5 kW | 15 kW |
| Reference output | 8-12 kg/h | 16-20 kg/h |
| Material | PLA raw material pellets and approved PLA compounds | |
| Filament size | 1.75 mm, 2.85 mm and 3 mm, subject to die and process setup | |
| Diameter control | Online laser measurement; target tolerance confirmed against the buyer's standard | |
| Downstream | Servo haul-off, spool winding, inspection and export packing | |
For a PLA project quotation, provide the material grade, additive or color formula, target diameter, tolerance, output, spool size, local voltage and whether biodegradable or compostability documentation is required. Confirm the required factory length, operator access, cooling utilities and local electrical standard before final equipment selection.
Factory, Packaging & Exhibition
Winsoar supports filament equipment projects from material and product specification review through assembly, checking, export packaging, container loading and customer communication. The support images below show the project workflow around plastic extrusion equipment.
The workshop supports equipment assembly, electrical checking and line layout preparation before shipment.
Mechanical components, electrical controls, dies and accessories are checked against the confirmed project configuration.
Packaging is selected according to equipment dimensions, transport distance and unloading conditions.
Loading is organized to protect long equipment sections and smaller precision parts during overseas transport.
Technical discussions help confirm material, target diameter, output, spool format and factory conditions.
Filament samples help compare surface quality, diameter, color, spool winding and printing requirements.
For a PLA project quotation, provide the material grade, additive or color formula, target diameter, tolerance, output, spool size, local voltage and whether biodegradable or compostability documentation is required.
The line is designed for PLA raw material pellets and approved PLA compounds. Color masterbatch, additives, filled formulations and other compound changes should be confirmed with the material data sheet, drying requirement, melt behavior and target filament diameter before final configuration.
No. The claim depends on the PLA formulation, additives, certification and disposal or industrial composting conditions. The production line can make PLA filament, but the finished product claim must be supported by the selected material supplier and applicable market requirements.
Common configurations include 1.75 mm, 2.85 mm and 3 mm. The die, cooling, haul-off and winding settings must be matched to the selected diameter and the buyer's target tolerance.
Please provide PLA grade, additive or color formula, target diameter, output in kg/h, tolerance, spool size, local voltage, workshop length and any biodegradable or compostability documentation required for the finished filament.
