On July 8, 2020, Polymaker  announced  at the TCT Asia exhibition that it officially released its new 3D printing pellet 

product line, the PolyCore™ series.

       In recent years,  the super-large 3D printing technology promoted by the US Oak Grove National Laboratory has 

developed  rapidly.  When  manufacturing  large-scale   components, this technology has outstanding advantages in 

terms of cost, efficiency and craftsmanship, and has a broad prospect on the application side.

Case number one

Tongji University Yichi-Racing Car Shell Mould
Application category: Mould

Moulds are the most advantageous application of super-sized 3D printing technology. In the manufacturing process, 

the basic shape is printed by 3D,  and then CNC machining is performed to create the final mold.  The entire process 

can be completed in about 24 hours. And the final mold size accuracy made by this process can reach 0.01mm.

        The Tongji University Yichi team used this new technology to make car shell molds. After laying the carbon fiber 

composite  material  on  the  mold,  it  is  placed  in  a  vacuum  autoclave.  After  the  autoclave equipment heats up, 

pressurizes,  heats up, cools down,  and releases pressure,  and after curing is completed,  remove the mold from the 

autoclave to obtain  car shell made of carbon fiber composite materials.  This kind of autoclave molding process puts 

forward  higher  requirements  on  the  heat  resistance  and  dimensional  stability  of  mold  materials.  Polymaker 

cooperated with Covestro to launch a 20%  carbon fiber  reinforced PC material-PolyCore™ PC-7422, which can meet 

the  requirements  of  autoclave  process  for  mold  heat resistance and dimensional stability. Polymaker's long-term 

partner, Kuying Robot, successfully completed the mold 3D printing and CNC machining and cutting post-processing 

work.

Case two
Shanghai Construction Engineering Group-Oversized 3D printed pedestrian landscape bridge
Application category: landscape sketch

      Shanghai Construction Engineering Group has two large-size 3D printed pedestrian landscape bridges, which are 

respectively  erected  in  Shanghai  Taopu  Central  Greenland  Park  and the Baiqi Lake Ecological Continuous Belt in 

Quanzhou,  Fujian.  The  perfect  combination  of Cool Eagle Robot's ability to control technology and craftsmanship 

and Polymaker's  control  of  materials have achieved these two current domestic large-scale 3D printing technology 

application  models  in  landscape  architecture.  Because  the  landscape  bridge is used outdoors,  Polymaker chose 

weather-resistant ASA material.

     Through the completion of practical application projects, Polymaker has mastered the test methods for super-size 

pellets 3D printing and has accumulated rich experience. It can not only provide customers of PolyCore™ pellets with 

high-quality  raw  materials  and  related  material technical information, but also Provide a full set of related services 

from testing, to printing, to post-processing.

    Polymaker always takes material technology as the core and application-oriented, exerting the synergy of materials, 

equipment  and software to create value for customers. Introduction: In the large-scale and large-scale manufacturing 

of FDM,  it is a trend to  directly use  granular  materials,  which  not only has higher molding efficiency, but also lower 

material costs.
