The startup Parastruct has attracted attention, especially after winning in the \u201cWaste Management and Recycling\u201d category from Kurier magazine. With innovative solutions that follow the principles of circular production, the company is at the forefront when it comes to pursuing a sustainable path in the construction sector<\/a>. But that is not all. In our interview with Parastruct\u2019s founder, Georg Breitenberger, he tells us about the philosophy behind circular production, the goals of the young company, and gives a comprehensive overview of the technologies Parastruct uses. The former master bricklayer draws on numerous sources of experience, from his artisanal training to study trips in Taiwan, to help shape Parastruct\u2019s way of operating.

3DN: Could you briefly introduce yourself and tell us how you first got involved with 3D printing?<\/h2>\n
\"Georg

Georg Breitenberger founded Parastruct in 2021.<\/p><\/div>\n

My name is Georg Breitenberger, and I am a master bricklayer by trade. I later studied civil engineering and business administration, and then worked for a time in real estate development and the precast concrete industry. In 2021, I decided to found Parastruct. At Parastruct, we develop sustainable materials from biogenic and mineral waste. We create these materials for 3D printing in the construction industry and foster collaborative projects between machinery manufacturers and 3D printing solution providers.<\/p>\n

I first came into contact with 3D printing about ten years ago, almost by chance. I have always been interested in new technologies, and during my rather dull studies, I learned about 3D concrete printing through a friend. By coincidence, I was working at a laboratory in a technical testing and research institute at the time. This eventually led to a larger project at a university in Taiwan, which at that time was the only source of funding for our project. Later, the precast concrete industry took notice, and I subsequently developed 3D printers and materials for various companies.<\/p>

3DN: How was Parastruct founded, and what is its mission?<\/h2>\n

I founded Parastruct to implement my own vision in the field of 3D printing for the construction industry, where I saw enormous potential for 3D printing processes, especially powder-based printing. Binder jetting<\/a> will revolutionize component production and is the most powerful tool the construction industry has to address future challenges such as sustainability issues, skilled labor shortages, increased productivity, and price stability.<\/p>\n

What we do at Parastruct is what we call Circular Advanced Manufacturing. Through our sustainable materials and 3D printing methods, we aim to make construction more functional, sustainable, customizable, and affordable. The construction industry is the largest emitter of CO2 and the biggest producer of waste. We use biogenic and mineral waste, combine it with our low-carbon binders, and produce sustainable and cost-effective 3D printing materials.<\/p>\n

\"\"<\/p>\n

3DN: What technologies and materials do you use, and why?<\/h2>\n

We use certain in-house recycling methods to extract and reactivate mineral binders from waste and byproducts. We use these binders to create sustainable materials for the conventional construction industry, especially for the precast concrete sector. But we also develop materials for 3D printing processes<\/a>. Here, we work with Contour Crafting (an extrusion process), Selective Binder Activation and Paste Intrusion (a powder-based printing process), as well as Mineral Binder Lithography, a new process developed by Parastruct. Each of these 3D printing technologies has its own advantages, disadvantages, and applications. It is essential to understand them thoroughly to create meaningful products from these technologies. Printing an entire house is not economically viable.<\/p>\n

Additionally, we only use biogenic and mineral materials. Most of the time, these are waste materials and byproducts that we convert into 3D printing materials that are sustainable and non-toxic. Thanks to our binder recycling, these materials can also be reused after their lifecycle.<\/p>\n

3DN: We understand that you focus on circular production. How do you implement this circularity?<\/h2>\n

For us at Parastruct, circularity is not just an ecological principle but a technological design framework. We implement it on multiple levels, using innovative materials, circular processes, and digital manufacturing technologies like 3D printing. Our company concept is built on four main pillars:<\/p>\n
