FOR IMMEDIATE RELEASE
Lancaster, California — February 19, 2018. A little less than a year ago RedWorks Construction Technologies Inc. began work on our first On-Site Material 3D Printer with a simple goal: make it possible to create whatever materials a builder could need with the dirt beneath their feet. In October of 2017 we proved that was possible with our first prototype extruder, creating granite-like material from ordinary sand. Now we are working to create a machine to change the face of construction.
RedWorksTM In-Situ Additive Construction (ISAC) 3D Printers only require on-site sources of dirt, dust, and sand to create materials that can match the strength of existing masonry. Our technology will let builders make custom, high-end stone building materials faster, cheaper, and with far less waste. Our first commercially available prototype, set to launch later this year, will be introduced for architects, universities, and government researchers looking to experiment with on-site 3D printing. These tabletop, or T-Series, printers will directly precede our larger P-Series ISAC printers which will be small enough to fit in the bed of a pickup truck and will enable commercial builders to create low-cost masonry materials on-site. ISAC will let builders create materials for high-end projects without disrupting local communities and environments with diesel burning cement trucks. Low cost housing hugging a highway can be built with thick walls to reduce noise pollution for residents and neighbors alike, when they’d otherwise be prohibitively expensive. And communities impacted by drought could create apartments and homes from blocks designed to collect rainwater and distribute it to planters that that reduce air pollution and retain water. These are just a few of the opportunities that ISAC will make possible, and fundamentally change the way we approach construction.
At the heart of the ISAC printers is RedWorksTM patent pending Multi-Core Induction Extruder (M-CIE). M-CIE is a new kind of 3D printer extrusion technology that sinters dirt and sand to a malleable state, with no water or binders, using induction heating. Put simply, induction uses a magnetic field to force the molecules in a conductive material to vibrate, generating friction and therefore heat. However, unlike past induction systems that can only use conductive metals and certain ceramics, M-CIE’s unique design uses inducting heating indirectly. Heating conductive cores within the print-head to many hundreds of degrees, dirt and sand feedstocks are continuously fed through and heated to become semi-molten and malleable. The material is then laid down like any plastic 3D printer to make whatever objects the user desires, before cooling to become rock. This is actually a fairly energy efficient process compared to current masonry production technology, requiring as little as 10 kilowatts to work. In California, energy costs are so low that a standard working brick printed using a P-Series ISAC printer would cost as little as 1/50th that of commercially available materials. Moreover, by shrinking the supply chain to the builder, ISAC will significantly reduce material shipping costs, and more importantly eliminate shipping delays for masonry.
In an industry ripe for technology that will disrupt costs and support greater flexibility, ISAC is a game changer. We hope to make ISAC the machine that empowers builders and contractors to meet the demands of an ever evolving market. From high-end projects that complement their environment, to affordable housing that raises the value of neighborhoods, ISAC will reduce building materials and costs to the dirt beneath your feet.
