3D printing helps. But, do we need it?

Hey! Jonathan here.
When new technology arrives, usually comes with great energy and excitement, often accompanied by the word “revolution”. Let’s look at one that is changing —or shaping— the way architects and students are approaching their architectural ideal and build models: 3D printing.
The basics: It’s a machine that allows creates a product in three dimensions by layering successive layers of material such as PLA or nylon. It brings to the table various elements. First, accuracy and precision are guaranteed, especially in complex models which can be difficult to create with manual techniques. Second, it’s fast, allowing architects to iterate, make design decisions, and create more test in a short period of time. Third, it can be environmentally friendly, because it can use recycled materials. In general, it is presented as a new way for visualizing a project.
But new technology implies new workflows and new ways of thinking about the prototype. What has been their impact until now? According to a literate review about 3D printing and architectural design, research about this intersection increased significantly between 2017 and 2018 with a focus on its application in design and education. In general, the research have shown that the integration of 3D printing technology in the design process can encourage creative thinking, leading to more complex design solutions compared to traditional teaching methods, as well as improve spatial cognition.
Will 3D printing be in mass use? The answer to that question is still some time away.

As you can imagine, buying a 3D printer is not like buying a pair of pants or the latest Taylor Swift album. Here are three aspect to tankin into consideration when getting one:
Printer size: the range of printer plate sizes is quite broad. There are some very small and some quite large. Consider the size of the models you plan to print when making your purchase. If you can only afford a small one for any reason, don't worry: you can always print the model in parts and glue them together. For building models in 1:500 or 1:200 scale, almost any model works. Context models usually need to be printed in several parts, even if you have a large printer.
Automatic leveling of the first layer: it's essential that the model is printed perfectly horizontal. If you buy a printer that doesn't automatically level the first layer, you'll need to spend time doing it manually.
Z-axis system: there are two methods that allow for vertical printing. In the first, the platform where the model is placed gradually lowers, and in the second, the extruder with the plastic filament rises. Printers where the platform lowers are usually enclosed structures, so the model is more protected and errors can be prevented.
Let’s think.
Typically, architectural models are made of cardboard, wood, or other malleable materials. These models are necessary to study various aspects of the design. However, 3D printing is becoming an increasingly popular alternative. Additionally, digital software allows changes to be made to the structures easily.
In this section, our purpose is to engage in deep conversations and debates around this field. Today, we propose the following question:
Is it counterproductive to design and prototype solely in the digital realm, without any physical contact with materials and their properties?
We look forward to your comments via email or on our Discord server. Soon on our Instagram account, we will summarize the conversation.
