My name is Phung Quoc Huy Hoang, born in 1995 in Nha Trang, and currently live and work in Ho Chi Minh City. I have been pursuing printing 3D products for 5 years now. Previously, I studied restaurant management at the Industrial University, but decided to stop studying in year 2 because I felt this was not my passion. 
During my self-study, I knew a brother on social media who worked on clay. A monkey head statue made by this man based on the movie Planet of the Apes was so beautiful that I was constantly learning about clay making. Those were the first steps that brought me into the 3D printing industry. 
Since October 2018, I founded Craftech – a combination of craft (craft) and tech (technology) – with the desire to create printed products based on these elements. The 3D printing market in Vietnam started to emerge from 2017, and has grown quite strongly up to now. Before that, when making a machine part, the worker had to cut CNC with iron and steel. In terms of art, it also takes time to hire people to carve or make from clay. In addition, cost is one of the reasons 3D printing is increasingly popular. Before that, people often covered with earth or porous to create shape. Then comes the process of making silicone molds, pouring plastic and removing it like jelly. It is this mold making step that causes the cost to be high. 
With a total of 10 employees, we only perform some main stages such as mechanical design, art drawing, accounting … Processes such as CNC cutting, mold making … will be assigned to the unit. other for cost optimization. All drawing design operations will be done by computer simulation software. 
The 12 V printer consumes electricity about 3-4 million / month. When printing, the layers are overlapped and formatted under the control of the computer. These printers were bought by me at a local company with the price of over 10 million VND / 1 machine. The drawing is fed into the machine. I make some adjustments before printing starts. 
The material is melted before printing. Depending on the nozzle, the plastic wire is packed into rolls of different size. The ingredients are quite easy to buy in Vietnam. 
The glue part helps the sample stick to the 3D printing table. For large-sized products, we will assemble each part instead of printing the whole, because the printing size of the machine is only 40 cm2. 
Small printers also work in a similar way to large machines. 
This is a product of a small printer. We used to produce finished products with sizes as low as 2 cm. 
Some products are forced to print on a liquid machine because they require many small details that take weeks to complete. Not to mention, for products to achieve high perfection, manufacturers also need to coordinate many materials. 
Depending on the order, we will choose the appropriate production method. For example, direct printing would apply to event bookers requiring 10-20 products. With the requirements of mass production, quantity of tens of thousands, we have to make silicon molds or steel molds. 
This is a product we made for the dinosaur program organizer in Hai Phong. However, this project is manufactured from composite or silicon, not 3D printed. 
The biggest, most expensive 3D printed product we’ve ever made is a 5-meter bear delivered to a milk tea shop. In the workshop there are now more expensive projects, but made of silicon resin and molded composite, not 3D printing. 
A shipment is transported by us to customers in Phu Quoc. For bulky products, I have to pay a car rental fee. Up to now, the highest value project the company has ever implemented is a miniatures set at 1.8 billion dong. 
We do daily activities right at the factory. Currently the company is preparing projects for customers in the central region. I have surveyed but still have a lot of work in progress.
