While we are now used to seeing 3D printed houses, bridges or even pop-up stores, as far as we know, no religious building has yet been designed using additive manufacturing. The Lake California Community Church has contracted the American company Don Ajamian Construction and the 3D printing company Emergent 3D to build a church. Commenting on the reasons behind the move, Jim Laxson, the paster of Lake California Community Church explained, “We’ve been trying to build a church for 20 years now and now, with 3D printing, we’re going to be able to build it more economically.” Don Ajamian certainly agrees, though he considers that the benefits of additive manufacturing are not only about the reduced cost of construction. The 3D printed interior walls were designed to provide perfect acoustics by directing sound waves directly to the audience. Why 3D Printing? As previously mentioned, a large reason the Lake California Community Church hired Emergent 3D was to minimize construction costs. To print the church, the two companies said they used COBOD’s 3D solutions, which are often used in large-format construction 3D printing projects. Don Ajamian further explained, “So I do not need to, for example, bring a bunch of stucco guys to put stuff on the outside or put siding on it. I don’t need to bring a bunch of drywall people in to drywall the inside wall. Literally, when these things get printed, that wall is finished other than the paint.” Though for now, only the site grading has been completed, according to the companies, 3D printing is expected to begin in the summer of 2022.
