Top 12 manufacturers of 3D printed houses and buildings

3D printing technology, aka additive manufacturing (AM), has been around for the past 30 years. Perhaps, it was only recently that as manufacturing technology, it started to attract interest in both the academic community and the business world.

The promise of its future impact on traditional manufacturing processes is unpredictable. However, it seems that 3D printing will propel the revolution of fabrication modes forward, and bring in a new era for customized fabrication.

Additive manufacturing typically means a process of joining materials to make objects from 3D model data, usually layer upon layer, as opposed to subtractive manufacturing methodologies. Due to its ability to manage small volumes, intricate designs, and light-weight but strong structures, technology is transforming the way that many industries operate.

Guided by computer-aided design (or CAD) file, 3D printers can use different materials, including plastic, metal, and ceramics, to produce three-dimensional objects like a machine or product prototypes, special tools and end-use parts for a variety of industries – including aerospace, aviation, automotive, health care, tourism, and others.

Currently, the technology faces some challenges associated with size and scalability, high material costs, a narrow range of materials, limited multi-material printing capabilities, and quality consistency issues. However, the continuing advancements in the AM technology and material sciences are likely to address these limitations and are expected to drive broader adoption.

This post will explore some of the top manufacturers of 3D printed houses and cabins in the world.

1. Apis Cor

Russian robotic construction company Apis Cor is the first company to develop specialized equipment for printing an entire building (walls and structures) on-site. It built a 3D construction printer, capable of fully printing a house in any place within 24 hours under any weather conditions. This first mobile circular construction 3D printer, transported on a crane, is 4.5 meters long, 1.5 meters high and wide.

This solution requires only 30 minutes to set up. It features a stabilization system and “mobile automated mix and supply unit” and control program to facilitate the construction work.
