SJ-35 / SJ-45 - 1.75 mm
Product Description
Direct answer: This machine is focused on the common 1.75 mm filament market. The compact layout helps small and medium filament producers control workshop space while maintaining a continuous process from pellet feeding to spool winding. ABS is suitable for functional parts and housings; PLA is suitable for prototypes, education and general-purpose printing.
The Winsoar 1.75 mm ABS PLA filament extrusion machine is a compact production solution for standard desktop 3D printer filament. It integrates pellet drying, single-screw extrusion, precision die forming, hot and cold water cooling, online diameter inspection, servo haul-off and controlled spool winding. The same platform can be configured for approved PLA, ABS and selected thermoplastic compounds.
1.75 mm PLA filament for desktop FDM printers
1.75 mm ABS filament for functional parts and housings
Private-label filament production for distributors and 3D printing brands
Color and formulation changeover projects after material testing
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.
Dedicated die setup for stable 1.75 mm filament forming
Compact line arrangement for limited workshop space
Drying hopper for moisture-sensitive PLA and controlled material preparation
Cooling and sizing sections matched to diameter stability requirements
Laser gauge and synchronized haul-off for reduced diameter fluctuation
Neat spool winding for labeling, packing and overseas shipment
For a 1.75 mm line quotation, provide the target raw material grade, output in kg/h, diameter tolerance, color change frequency, spool weight, local electrical standard and available line length.
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, ABS and selected thermoplastic 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 1.75 mm line quotation, provide the target raw material grade, output in kg/h, diameter tolerance, color change frequency, spool weight, local electrical standard and available line length. 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 1.75 mm line quotation, provide the target raw material grade, output in kg/h, diameter tolerance, color change frequency, spool weight, local electrical standard and available line length.
1.75 mm is a common filament size for desktop FDM and FFF printers. It is suitable for standard spool products, private-label filament brands and general consumer or educational printing when the final diameter and ovality meet the buyer's quality standard.
It can be configured for ABS and PLA raw material pellets after the material grade, screw and die conditions, temperature profile, cooling method and cleaning or color-change procedure are confirmed.
The process combines controlled extrusion, staged cooling, online laser diameter measurement, synchronized haul-off and controlled-tension winding. Actual tolerance depends on the material, die, process settings and quality standard.
Confirm ABS or PLA grade, target output, diameter tolerance, color-change frequency, spool weight, winding format, local electrical standard and available line length before the final machine configuration is prepared.
