- 4. CONTENTS 3D printing 3D printing in construction 3D printing technology process History of 3D printing technology Comparison with other technologies Future benefits Disadvantages of 3D printing technology 3D moon building.
- 5. 3D Printing Computer controlled sequential layering of material. To create three-dimensional (3D) shapes.
- 6. Construction 3D Printing 3DCP refers to various technologies that use 3D Printing as a core method to fabricate building or construction components. It is also known as: Rapid prototyping Additive manufacturing.
- 9. General principles Modeling. Printing. Finishing.
- 10. Process of 3D building construction: 1.A person creates a 3D image of an item using a CAD software program. 2.The CAD information is sent to the printer. 3.The printer forms the item by depositing the material in layers-starting from bottom layer .In some cases light or lasers are used to harden the material.
- 11. History The technology for printing physical 3D object from digital data was first developed by Chuck Hull in 1984. The father of 3D printing.
- 12. First 3D House In World In French. Overall the 95 metre. Within 54 hours. The building cost is 20% cheaper than an identical construction with traditional methods. Good thermal resistance, air circulation.
- 14. COMPARISON BETWEEN 3D PRINTING AND OTHER CONSTRUCTION TECHNOLOGIES
- 15. ENVIRONMENT 3D printing major environmentally friendly. waste reduction. plastics,resin,certain metals,ceramics are used. no environmental impact. no pollution. no waste. other technologies more waste production. plastics, ceramics are not used in some construction technologies. Environmental impact. co2 is emitted. pollution.
- 16. COST 3D printing low material cost. low labor cost. the printer does most of the work. great for business’ bottom line. Other technologies large material cost. high labor cost. take large time. the labors do most of the work.
- 17. TIME CONSUMPTION 3D printer low time consumption. One day is enough. within 42 hours, 3D printer build a big house. other technologies high time consumption. Minimum 6 mouths are required. high cost.
- 18. THE FUTURE BENEFITS FOR 3D PRINTING IN THE CONSTRUCTION
- 19. NEW SHAPES AND DESIGN POSSIBILITIES flexible in the shapes of the designs. build curvilinear and rectilinear structure easily strongest structural. any shapes and size.
- 20. LOW COST low cost on both a large structure scale and regard to parts. have potential for far lower material costs and labor. very helpful for poor people. in China , they can be produced for less than $5,000.
- 21. REMOTE LOCATION CONSTRUCTION out of this world use of 3D printing. moon building. 3D printing could take us anywhere.
- 22. MORE PRECISE BUILDING better and more precise results. on small amount of area, 3D printer build more precise building.
- 23. PRINTING OF 3D BRIDGE AND CANAL
- 24. BUILDING THE WORLD’S FIRST PEDESTRIAN 3D BRIDGE on 26th December 2016. in Madrid, Spain. 12 meters in length. 1.75 meters wide. Build by waste material.
- 26. BUILDING A CANAL In Amsterdam. In 2014. The printer used 3D plastic to construct the canal. WAAM 3D printing is used. Build by waste material with other material.
- 28. DISADVANTAGES automated fabrication is not suitable for large scale products and conventional design approaches. Smaller ratio of automated products in comparison with other industries. only limited material can be used by automated machines. Reduced employee numbers in the industry, as the 3D printer does most of the work.
- 29. transportation of the printer to the site and safe storage of it on site is problematic. any error in the digital model can result in problematic issues on site during the printing or construction phase , that may require special handing . manufacture of conventional building products and plant renting companies could suffer as their products demand may decrease.
- 30. 3D PRINTED MOON BUILDING The building have to build on moon from material already on its surface. The printers , operated by robots, would use soil from the moon. Site-the southern pole of the moon. Silicon, aluminium, calcium, iron, magnesium oxide could be used by 3D printer. first we plan the building plan with the help of CADD software. It send to 3D printer to moon with robots. 3D printer build the building on moon with moonsoil. Hopes to be ready to start production by 2020.
