On October 17, 2019, Antarctic Bear found a domestic manufacturer specializing in 3D printing post-processing of nylon/TPU and other materials at the TCT Shenzhen exhibition - Dongguan DYEWIN. The post-processing systems such as surface treatment of 3D printing parts and dyeing of 3D printing parts independently developed by them have filled many gaps in domestic intelligent equipment for post-processing of 3D printing, and have reached the international level. What is even more impressive is that the price of this set of clear powder + surface fine treatment + dyeing system is only 20% of that of similar imported products from abroad. 3D printing post-processing equipment. △3D printed nylon balls post-processed by Dyewin smart devices

According to Antarctic Bear, Dyewin Smart is a high-tech enterprise focusing on the research and development of 3D printing parts surface treatment and parts dyeing equipment. It was founded by an excellent team with many years of experience in aerospace additive manufacturing. They provide DYEWIN series post-processing finishing systems, which can quickly process 3D-printed original parts into high-value products. With the self-developed DYEWIN series post-processing systems, the surface treatment of 3D-printed original parts is more perfect, so that the original 3D printed parts with a single color are more perfect. Printed parts get a more multi-color experience to meet the needs of different users.

Features of the post-processing system
-
High degree of intelligence, intelligent operation, reduce labor
-
The surface treatment effect is good. Through the self-developed surface treatment technology and materials, the surface fineness, gloss and wear resistance of nylon products can be effectively improved.
-
Rich in color, there are 12 standard colors, and PANTONE colors can also be customized
-
Environmental protection, the system design meets environmental protection standards, and the sand and dyes used have the inspection certificate issued by the inspection organization

DYEWIN Series 3D printing post-processing system workflow
DYEWIN series 3D printing post-processing system, it only takes two hours from 3D printing original parts to high-value finished products, and completes the finishing of 3D printing original parts in three steps according to the workflow, which greatly shortens the time from prototype or small batch to high-end products. The time when the value finished product is produced.
The first step: powder cleaning on the surface of the part, DYEWIN AUTO-JET C automatically removes impurities and excess printing material on the surface of the part. One-key start, automatically remove the powder of 3D printing parts in batches, which is equivalent to the processing speed of 3-4 manual sandblasting machines, which greatly improves the powder removal efficiency and reduces the cost. The equipment can choose automatic processing or manual processing according to needs; large-sized and complex parts can be processed manually, and small-sized batches can be processed automatically.
The second step: Parts surface finishing treatment, DYEWIN AUTO-JET P uses the special sand developed by Dewei to improve the surface quality of the parts and make the surface of the parts smoother and brighter.

The equipment is equipped with a separator, which can well remove impurities and dust in the special sand, reduce material waste, improve material utilization, and save costs.
The third step: parts dyeing, DYEWIN DW-50/20, automatic dyeing system can quickly get the desired color.

The parts dyeing system is simple and easy to use. According to the type of dyes put in, select the dyeing formula on the touch screen, start the dyeing process, and complete the dyeing process. The whole dyeing process does not require manual intervention; the dyeing efficiency is high, and it has a 50L dyeing container, which can be used in one dyeing cycle. A maximum of about 4KG (recommended 2KG) can be dyed for parts at one time, which is fully capable of mass customization of 3D printing; high dyeing quality: high dyeing rate of parts, and uniform dyeing surface. The dyeing depth is guaranteed by high temperature and high pressure, and the color fastness is high and does not fade. Suitable for polymer 3D printing parts, such as PA12, PA11, etc.; to ensure the original performance of 3D printing parts, the dyeing process does not damage the material code, and does not change the microstructure of the material, thereby ensuring the original mechanical properties of the material.

Wang Xingying of Dyewin Intelligent told Antarctic Bear that the DYEWIN series products are compatible with all commonly used 3D printing equipment materials, and can meet the post-processing requirements of additively manufactured plastics and specially optimized PA11, PA12, PA6/TPU or photosensitive resin-based materials. At present, the post-processing of 3D printing products of HP, Farsoon, Yingpu and other companies has been perfectly realized. After Dyewin intelligent post-processing, the application scope of 3D printing of nylon and other materials can be greatly expanded. At present, the equipment has been sold to Europe, Southeast Asia and other regions, and a number of 3D printing equipment manufacturers and service providers including HP have purchased the equipment. |
