Explore the Connection Between 3D Printing Technology and Art and Design
In the second half of this year, a "Squid Game" directed by Hwang Dong-hyuk became popular all over the world. The play tells the story of a survival game involving 456 Koreans with huge debts to please international capitalists. In the process of watching the movie, the masks in the play left a deep impression on me. Masks are mainly divided into two categories, one category belongs to game executives, and the other category belongs to international capitalists. In this article, I will analyze these masks from the perspective of light curing technology.
We need to understand the light curing molding technology first. "This technology uses a UV laser to accurately cure the cross-section of the photopolymer and transform it from a fluid to a solid." Here I am directly quoting the explanation of the technology on the official website of 3D Systems, because Chuck Hull, the inventor of the technology, is the co-founder of this company. Of course, a more popular explanation is that UV light is scanned on the surface or bottom of the photosensitive resin, and one layer is condensed every time it is scanned, and the model is printed layer by layer through continuous scanning. The domestic light curing molding technology can be roughly divided into SLA, DLP and LCD, here I will focus on the most common SLA.
Back to the mask, the shape of the first type of mask is relatively simple, and it is roughly composed of curved surfaces and meshes. The second type of mask uses the face of an animal as a reference. Here I choose three representative masks as examples. Through the data simulation of the mask, the newly printed mask, and the mask after removing the support, these three nodes will gradually uncover the application range of the light-curing molding technology.
First of all, among masks 1, 2 and 3, the light-curing molding technology should be used most in mask 3, because its final effect is electroplating gold. If an object is to show the best coloring effect, its surface must be smooth. In the existing three-dimensional molding technology, the photosensitive resin after high-precision polishing is the most ideal choice. Therefore, through mask 3, two application areas are obtained: smooth surface and coloring.

△Print the newly completed mask
△Remove the support mask
Next, compare masks 1 and 2. Judging from the intuition, Mask 2 is not suitable for light-curing molding technology, because most of the surfaces are made of meshes, so there are holes on the surface. In the illusion of light-curing molding technology, having holes means that you need to add support to achieve printing, so each hole will have support, which will increase the difficulty of post-processing. However, after observing the data simulation and the printed mask, you will find that there is no support in the hole. This is because the light-curing molding technology can achieve unsupported printing when the printing angle is higher than 30 degrees. Moreover, because the mask is made of a grid, the area of the mask 2 that needs to be post-processed is much lower than that of the mask 1, so the mask 2 is more suitable for light-curing molding technology than the mask 1. Here comes the third application range: the printing angle is higher than 30 degrees, and the light-curing molding technology can realize unsupported printing. Combining the experience of mask 2 and mask 3, it can be concluded that mask 1 is also suitable for light-curing molding technology, because the surface needs to be smooth and the hole angle of the eye area is higher than 30 degrees.
Through the above cases, three basic application areas are drawn: smooth surface, coloring and printing angles higher than 30 degrees. Later, I will use the disadvantages of light-curing molding technology to deduce the applicable scenarios and application directions in art and design.
According to personal production experience, there are three main disadvantages of light-curing molding technology: yellowing and deformation caused by long-term outdoor placement, and large gaps in the edges of the splicing after disassembly. "The Story of Flowers.8" is the larger one of my works, and it is printed separately from white and transparent photosensitive resins and put them together. Although this work was placed indoors, due to long-term bathing in a space that can be exposed to sunlight, yellowing and deformation eventually appeared. And because it was divided into two parts during printing, there was a significant displacement in the splicing part during the splicing process.

Based on the above three obvious disadvantages, the applicable scenarios of light curing molding technology in art and design can be reflected as: indoor, short-term and models that do not require a large number of splicing, so I think medium-sized decorative parts are the most suitable for light curing. The application direction of molding technology. Such a direction is very widespread in cities, such as: window design, indoor shopping malls and decorative pieces needed for short-term outdoor activities
With the continuous improvement of SLA molding area and the continuous reduction of splicing errors, combined with relatively stable outdoor coatings, I think this technology will be widely used in public art and urban sculpture in the future. And there is the popularization of high-precision printing technologies like DLP and LCD, and the hand-made industry will also use this technology on a large scale in the terminals of its own product lines. In the next article, I will also talk about the application of nylon and metal printing in art and design through some practical cases and personal works..
