Bringing 3D Printing Home—to Actual Homes – Machine Design (blog)

by • January 12, 2016 • No Comments

The thought of a 3D-printed house began with a easy concept, using a programmable Cartesian coordinate system to extrude cement into layers creating a tiny, single-story living space. In another approach, a few designers created 3D-printed parts which may and so be assembled into a assembling. This technique can be done on-site and can offer donate-chain benefits, as well as solve a few problems when printing cement, such as attempting to print a 2nd floor, overhangs, or balconies.
​WinSun is one of the companies producing the modular cement designs and in the last year utilized 3D-printing techniques to print a five-story assembling, mansions, and other houses in China. While a few companies are working on designs to print on-site, others will print parts and and so transport them. Transporting prints can have a few of the same problems a traditional donate chain must deal with, which include the possibility of parts and trusses breaking. But, WinSun says by using this technique it improved system efficiency by 10 times, shortened production time up to 70%, and decreased labor cost by up to 80%.

An Italian company named World’s Advanced Saving Project (WASP) is working on a additional mobile design. Allowing on-site printing may generate an entire assembling rather than the modular design. This approach limits the assembling’s dimensions, but other techniques may increase the build space. Engineers have presented thoughts of tracks or wheels to move the whole printer to construct sizeabler assemblings. One other option not utilized yet (if you have, please contact me at jeff.kerns@penton.com) is a cement 3D printer on a multi-axis arm with a gantry system. This is most likely due to the mass of the cement and cost, but may offer new techniques in 3D-printed houses which may offer additional degrees of freedom.
While most individuals say 3D printing houses is a gimmick and will never catch on, it may work well in developing nations and may be a solution for areas which undergo rapid expansion where traditional construction can’t keep up. 3D-printed houses are revealing the same benefits and limitations as in other 3D printing systemes. Engineers require to grow the technology and find out where it fits if it’s going to have any longevity in the construction industry.
3D printing houses, like 3D printing other parts, will not completely replace traditional systemes, but it adds another tool to help engineers go on to develop new and informative solutions. To further this technology, designers should remember to take advantage of inherent properties to increase the benefits of this construction technique. Solar thermal applications may work well with this technique. Offering conventional loop housing and the insulation value of the materials can greatly increase the HVAC efficiency. For example, strategically placed windows with a cement floor may offer awe-inspiring opportunity for passive solar. The truss design can provide voids in the walls for networking and insulation, or perhaps act as rainwater storage space. Continuing the thought of sustainable assemblings, these printing devices are may already taking advantage of post-consumer assembling materials in the cement. Ultimately, 3D-printed houses may not create it over the chasm. There may never be a college course on 3D printing a assembling in architecture school, but with the right designers and engineers this system might find a home in the construction industry in the future.
3D-printed houses or other products are much like in the following ways:Beneficial where labor costs are high or limited, or labor is unskilled to handle tasksWorks well in remote areas where getting supplies can prove complexCan reduce concerns where a sole supplier or rapid demand stunts donate-chain flowCan be teamed with traditional systemes to alleviate bottlenecks in productionCan be limited by build space, but can in addition offer modular designs to create sizeabler piecesTime-to-print can be a sizeable factor if this system is to be additional efficient than traditional techniquesFail prints may not just cost material and sizeable amounts of time, but in addition be dangerous on sizeable construction piecesComplex shape and interiors can be additional cost-effective and generate shapes too complex than in traditional systemes
