With the continuous improvement of personalized demand in the mannequin industry, there are more and more orders, and the demand for the same product is getting lesser and lesser. For the mannequins industry where a set of molds requires nearly hundreds of thousands to male, the market is becoming more and more difficult to survive, and a new manufacture method is urgently needed in order to upgrade and change the mannequin industry.
In November 2020, Anwei Plastics and Datong Machinery came to Imai to discuss the possibility of 3D printing mannequins. Both Imai and these two mannequin companies believe that 3D printing (FDM) technology is very suitable for the mannequin industry.
First of all, the high degree of freedom of 3D printing is extremely attractive to model manufacturing who do not want to open molds. 3D printing (FDM) technology is to form a solid product by stacking layers of sliced three-dimensional models. In this process, users only need to build a three-dimensional model, select the appropriate 3D printing material, and print it directly with a 3D printer. There is no need to open a set of assist molds in product molding.
Secondly, no matter how the user’s design is adjusted or changed, he/she only needs to make corresponding modifications on the 3D model, and then import the model to the slicing software to convert it into a G code that can be recognized by the 3D printer for printing. There is no need to redesign and make molds, and there is no need to manually engrave which is very labor-intensive and time-consuming. Users can get a newly designed model within 50 hours.
Third, there are many types of materials for 3D printing (FDM) technology. Imai recommend PLA, PETG, and ABS, three types of 3D printing filaments to Anwei and Datong. It has been proven that these three materials can meet the needs of customers in various application scenarios.
PLA is a palstic extracted from starch (Usually corn) and has little impact on the environment. It is a derivative of starch, green, renewable, and a biodegradable material (degrades itself in the soil) and is not harmful to the environment.
PETG is a durable material that is easy to use. It has strong impact resistance, making it an alternative material for PMMA and PC.
ABS is a thermoplastic polymer material with high strength, high rigidity and easy processing. Due to its strong physical properties, heat resistance and chemical resistance, it is usually used as a plastic housing for equipment.
Fourth,Imai recommended the Delta 3D printer YM-1200 and YM-300 to both customers. YM-1200 and YM-300 can be used together to print out a set of adult models of original scale within 24 hours. They can print PLA, PETG, ABS materials very well, and the speed is 30% faster than XYZ structure 3D printers.
Fifth, Imai combined with its own practical experience to solve many doubts of Anwei and Datong about 3D printing. For example, the problem of the head-up point (Z-axis seam) formed in the 3D printing process, the problem of enlarged top layer texture, the problem of post-processing of 3D printed products, etc…
