1 00:00:00,000 --> 00:00:00,000 2 00:00:04,019 --> 00:00:06,380 So this project is the first time we've 3 00:00:06,380 --> 00:00:08,547 used a practical application of our 3D 4 00:00:08,547 --> 00:00:10,658 concrete printer which you see behind 5 00:00:10,658 --> 00:00:12,880 me . Uh , so we've actually printed the 6 00:00:12,880 --> 00:00:14,769 facility that the printer will be 7 00:00:14,769 --> 00:00:16,991 housed in moving forward . We currently 8 00:00:16,991 --> 00:00:19,213 stored it inside our core shop . So the 9 00:00:19,213 --> 00:00:21,102 print itself took us 6 days . The 10 00:00:21,102 --> 00:00:23,213 building that we're currently working 11 00:00:23,213 --> 00:00:25,269 on . Now that's the first of 6 . The 12 00:00:25,269 --> 00:00:27,436 building behind me is a 16 ft by 32 ft 13 00:00:27,436 --> 00:00:29,658 which for military engineers is kind of 14 00:00:29,658 --> 00:00:31,658 a magical dimension that's the same 15 00:00:31,658 --> 00:00:33,991 size as the number of our uh tents , um , 16 00:00:33,991 --> 00:00:36,615 so our intent with this design is to 17 00:00:36,615 --> 00:00:38,935 create a structure that's the concrete 18 00:00:38,935 --> 00:00:41,130 replacement for the tent . So the con 19 00:00:41,130 --> 00:00:42,908 ops would be if we move into an 20 00:00:42,908 --> 00:00:45,241 expeditionary environment we put airmen , 21 00:00:45,241 --> 00:00:47,241 sailors , soldiers , marines in the 22 00:00:47,241 --> 00:00:49,352 tents for the shortest amount of time 23 00:00:49,352 --> 00:00:51,408 possible and then very quickly start 24 00:00:51,408 --> 00:00:53,574 replacing those tents with 3D concrete 25 00:00:53,574 --> 00:00:55,074 printed structures so it's 26 00:00:55,074 --> 00:00:57,019 significantly more sustainable for 27 00:00:57,019 --> 00:00:59,241 fixed infrastructure like an airbase to 28 00:00:59,241 --> 00:00:58,849 have facilities that are made of 29 00:00:58,849 --> 00:01:02,650 concrete vices , pure adversaries and 30 00:01:02,650 --> 00:01:05,610 tents . This is our first full facility 31 00:01:05,610 --> 00:01:08,089 built in 9 days we're going from 32 00:01:08,089 --> 00:01:10,256 nothing to a fully complete building . 33 00:01:10,839 --> 00:01:13,080 Our desire is that eventually the 34 00:01:13,080 --> 00:01:15,191 design improves to the point where we 35 00:01:15,191 --> 00:01:17,247 can have an integrated wall and roof 36 00:01:17,247 --> 00:01:19,358 structure . So one of the benefits of 37 00:01:19,358 --> 00:01:21,524 3D printed concrete structures is that 38 00:01:21,524 --> 00:01:23,469 they can provide some protection , 39 00:01:23,469 --> 00:01:25,636 force protection and hardening for our 40 00:01:25,636 --> 00:01:27,691 airmen . Um , but that only works if 41 00:01:27,691 --> 00:01:29,802 you are protected overhead as well as 42 00:01:29,802 --> 00:01:31,858 from the sides . So our desire is to 43 00:01:31,858 --> 00:01:34,024 eventually have a design that gets rid 44 00:01:34,024 --> 00:01:35,913 of the wood roof truss , uh , and 45 00:01:35,913 --> 00:01:37,969 corrugated metal roofing and move to 46 00:01:37,969 --> 00:01:40,024 something that's integrated wall and 47 00:01:40,024 --> 00:01:39,989 roof protection for the airmen or the 48 00:01:39,989 --> 00:01:42,156 assets that are inside the structure . 49 00:01:42,279 --> 00:01:44,335 During our September drill , uh , we 50 00:01:44,335 --> 00:01:47,349 invited a number of VIPs and other 51 00:01:47,349 --> 00:01:49,293 action officers in the engineering 52 00:01:49,293 --> 00:01:51,460 space to come see our work in action , 53 00:01:51,460 --> 00:01:53,516 and our hope in bringing a number of 54 00:01:53,516 --> 00:01:55,516 VIPs to Martin State , uh , is that 55 00:01:55,516 --> 00:01:57,682 those entities can continue to develop 56 00:01:57,682 --> 00:01:59,905 in all those , uh , different areas . I 57 00:01:59,905 --> 00:02:01,905 was invited . By Lieutenant Colonel 58 00:02:01,905 --> 00:02:04,114 Brian Vickers to see the 3D print of a 59 00:02:04,114 --> 00:02:07,205 garage for one of their facilities , 60 00:02:07,514 --> 00:02:09,664 and they're using an Xhab 3D printer 61 00:02:09,664 --> 00:02:11,442 and seeker material . So at the 62 00:02:11,442 --> 00:02:13,553 University of Georgia developing a 3D 63 00:02:13,553 --> 00:02:15,775 concrete printing lab and we're working 64 00:02:15,775 --> 00:02:17,720 with the Strength lab , which is a 65 00:02:17,720 --> 00:02:19,331 structural testing lab . And 66 00:02:19,331 --> 00:02:21,442 particularly we're seeing today a lot 67 00:02:21,442 --> 00:02:23,608 of 3D printing being caught on and and 68 00:02:23,608 --> 00:02:25,720 people are using it and applying it , 69 00:02:25,720 --> 00:02:27,720 but to standardize it and make sure 70 00:02:27,720 --> 00:02:29,942 that it is something that is easily and 71 00:02:29,942 --> 00:02:32,108 readily accessible to the masses to be 72 00:02:32,108 --> 00:02:34,331 trusted , uh , what we want to do is 3D 73 00:02:34,331 --> 00:02:36,220 print many structures , prototype 74 00:02:36,220 --> 00:02:38,164 different structures , assess them 75 00:02:38,164 --> 00:02:40,220 through experimental testing whether 76 00:02:40,220 --> 00:02:42,220 that's flexual impact testing , and 77 00:02:42,220 --> 00:02:44,275 then . Generate models that can then 78 00:02:44,275 --> 00:02:43,876 approximate their behavior based on 79 00:02:43,876 --> 00:02:45,765 those experimental tests . It's a 80 00:02:45,765 --> 00:02:47,765 wonderful opportunity and I'm super 81 00:02:47,765 --> 00:02:49,932 grateful to be here and coming here to 82 00:02:49,932 --> 00:02:51,765 the base to see this actually in 83 00:02:51,765 --> 00:02:53,765 practice see the interest from many 84 00:02:53,765 --> 00:02:55,820 different stakeholders , seeing many 85 00:02:55,820 --> 00:02:58,043 different industry professionals coming 86 00:02:58,043 --> 00:03:00,209 here to also work with and participate 87 00:03:00,209 --> 00:03:02,265 in this 3D printing shows the future 88 00:03:02,265 --> 00:03:04,432 longevity of 3D printing as a viable . 89 00:03:04,432 --> 00:03:06,376 Uh , for construction , if you can 90 00:03:06,376 --> 00:03:08,487 think of it , we can print it as long 91 00:03:08,487 --> 00:03:08,192 as we can run it through the software 92 00:03:08,462 --> 00:03:10,572 and create the actual file that the 93 00:03:10,572 --> 00:03:12,662 printer needs to read to to use the 94 00:03:12,662 --> 00:03:14,606 print . So you're not limited to a 95 00:03:14,606 --> 00:03:16,829 square building anymore . You can print 96 00:03:16,829 --> 00:03:18,829 pretty much anything that you would 97 00:03:18,829 --> 00:03:20,773 like . This can provide a lot more 98 00:03:20,773 --> 00:03:22,829 security . There's a lot of research 99 00:03:22,829 --> 00:03:24,495 being done right now on blast 100 00:03:24,495 --> 00:03:26,551 resistance to the product that we're 101 00:03:26,551 --> 00:03:28,495 using . Different designs , how to 102 00:03:28,495 --> 00:03:30,495 absorb those concussions and things 103 00:03:30,495 --> 00:03:32,551 like that , which provide a lot more 104 00:03:32,551 --> 00:03:32,289 security and safety for our personnel 105 00:03:32,289 --> 00:03:34,345 down range . Performance of the team 106 00:03:34,345 --> 00:03:36,567 members themselves has been outstanding 107 00:03:36,567 --> 00:03:38,678 again , we've put in some very , very 108 00:03:38,678 --> 00:03:40,789 long days and we have fun while we're 109 00:03:40,789 --> 00:03:40,369 doing it . It's , it's a fun project to 110 00:03:40,369 --> 00:03:42,639 be on . It's , it's new and exciting 111 00:03:42,639 --> 00:03:44,861 technology , and we're happy to be part 112 00:03:44,861 --> 00:03:43,970 of it .
