The 3D printing consumables extrusion molding experimental machine consists of a precision single screw extruder, wire mold, cooling water tank, traction system, caliper system, winding system, and measurement and control system, which can achieve functions such as wire extrusion, cooling, diameter measurement and winding.

Product Performance

1. Small footprint and easy installation.
2. Low material usage and high precision. Compared with large-scale production lines for 3D printing consumables, testing can be done with only 0.6KG material, which can significantly save testing costs.
3. This machine adopts a more optimized heating and cooling system, divided into multiple temperature control zones, each with independent thermocouples, to keep the material temperature adjustable at all times to ensure product performance. Temperature control accuracy is up to ±1℃.
4. Adopting advanced Siemens PLC or Delta control system, with a 10 inch touch screen operation, this machine has high humanization, intelligence, and safety, and automatically and accurately displays the measurement of important parameters such as melt pressure, temperature, and wire diameter curve during the extrusion process.
5. The traction roller adopts servo motor with stable speed and stepless speed regulation. Forming a closed-loop control with the laser caliper, it can quickly respond to changes in extrusion speed. The accuracy of the wire diameter is stable at plus or minus 0.02mm.
6. The cycloidal mechanism is equipped with high-precision limit sensors, a wire tracing device, precise positioning, and a neat winding function. Prevent tangling and jamming of 3D printing consumables during use.
7. High performance servo motor, wide speed range, stable and reliable speed.

Applications

Suitable for ABS PLA, TPU/TPR elastomer, low-temperature PCL, water-soluble PVA Conventional polymer materials such as PE and PA6. High temperature models can be customized non-standard, with temperatures up to 450℃ and ±1℃, To meet the processing reguirements of PEEK, PEK, Pl isothermal special engineering plastic wire.

1. Performance testing of polymer material wire extrusion molding.
2. Formula design for plastic wire.
3. Optimization and control of plastic wire extrusion process parameters.
4. Used for extruding single/multi cavity, multi specification plastic wire.
5. Process optimization, cost control, and small-scale sampling, etc.
