3D-snøfnuggene i blomsterbedene under vinter-OL ble 3D-printet med urbant avfall
In the Winter Olympics-themed flower bed along Chang'an Street, there is a 3D printing black technology. This is a large flower bed with a height of 9.1 meters. The main scene is the emblems of the Winter Olympics and the Winter Paralympic Games. The blue and white "snowflakes" scattered on the ground are particularly eye-catching.
"The raw materials of these 'snowflakes' are urban solid waste, which is made by 3D printing technology after many complicated processes." said Jia Changchun, the producer of the snowflake sculpture and chairman of China Carbon Springfield (Beijing) Energy Technology Co., Ltd.
The "snowflakes" carry modern technology and the concept of zero-carbon environmental protection.
In order to help the "zero carbon" Winter Olympics, China Carbon Springfield developed and produced garden sketches, turning useless garbage into light and beautiful "snowflakes". The 3D printing solid waste technology it uses has the advantages of saving templates, materials, labor, and waste outbound transportation.
Det største snøfnugget har en diameter på 1,7 meter. I design og trykk bør tykkelse, bredde, imitasjon og robusthet vurderes. Det er også nødvendig å vurdere at det 3D-trykte produktet kan bære skjulte rørledninger og forsterkende ribber.
It is reported that after the display of flower beds along Chang'an Avenue is over, the "snowflakes" will be recovered and recycled.
3D-skanning-design-3D-utskrift, tilpassede hjelmer for nasjonale snølagsutøvere
Under the organization of the State Sports General Administration, the 3D Printing and Intelligent Manufacturing Research Center of Dongguan University of Technology (Associate Professor Li Nan's team) joined hands with Sikan Technology, integrated 3D scanning-design-3D printing technology, and participated in the research project of helmet equipment customization for athletes of the National Snow Team.
△ Direct hits the snowmobile race
Snøscooterens gjennomsnittshastighet er rundt 100 kilometer i timen, og makshastigheten kan nå 160 kilometer. Det har alltid vært kjent som F1 på is. Den raske-racingprosessen kan gi folk uforlignelig spennende sanseglede, som er snøscooterracingens største attraksjon. I en tilstand med så høy-hastighet er sikkerheten til idrettsutøvere høyeste prioritet. Hjelmutstyr er et viktig verneutstyr for å ivareta sikkerheten til snøscooterutøvere.
△ 3D scanning and printing exclusive helmet
Tidligere ble hjelmene og utstyret til det nasjonale snølaget hovedsakelig importert fra utlandet, og ble kvitt avhengigheten av utstyrsimport og deltok i konkurransen med hjelmer uavhengig utviklet og designet i Kina.
Due to the rich contour features of the human head, it is suitable to use the non-contact non-stick splicing technology. This time, the iReal 2E 3D scanner of Sikan Technology was selected to complete the acquisition of the 3D data of the athlete's head.
The iReal 3D scanner has high precision (up to 0.1mm), and can accurately obtain the 3D data of the athlete's head, and the helmet made of it has a good fit;
I den eksklusive modusen for portrettskanning, kan menneskekroppens ristebunke fjernes automatisk; ingen stikkpunkter er nødvendig under skanning, lyskilden er trygg og usynlig, og hele skanneprosessen er komfortabel og trygg;
I tillegg løser dens kombinerte array-strukturerte lysteknologi kreativt problemet med vanskelig innhenting av hår- og øyedata, noe som gjør hodedata mer komplette.
After using the iReal 2E 3D scanner to obtain accurate 3D data of the athlete's head, the design team can customize the design according to the athlete's head shape and tactical characteristics, and then use 3D printing technology to produce the final helmet product.
Ved å bruke China Aerospace T800 karbonfiber og rene karbonfibermaterialer, er den endelige hjelmens vekt 500g lettere enn forrige generasjon konkurransehjelmer, kun ca. 1100g, noe som effektivt reduserer vekten til idrettsutøvere.
At the same time, the buffer layer of the helmet adopts a lattice structure design, and the topol honeycomb structure protection system printed by Farsoon High-tech Flight TPU process creatively solves the problem of deformation of head details, and completes the perfect adaptation to the athlete's head shape, and It can bring extremely high heat flow efficiency.
3D-printing for å utvikle skirobot
Den siste tiden har en video av en skirobot vakt mye oppmerksomhet. I videoen tråkker en firbeint robot på en ski, og det er to snøballer på venstre og høyre side. Sving side til side og skli ned veldig dyktig, handlingen ser ut til å overgå nivået til de fleste nybegynnere.
Det er verdt å merke seg at 3D-utskriftsteknologi brukes i design og produksjon av skiroboten. Det kan ses av figuren at det ytre skallet og dekslene til lemmene til skiroboten er produsert av SLA 3D-utskriftsteknologi, og sprayes og farges på et senere tidspunkt. installert på roboten. I dag har 3D-utskriftsteknologi store effektivitets- og kostnadsfordeler ved produksjon av hus for denne typen robotprodukter.
△ Morphological structure design, 3D printing, production and installation
"We were invited to design the appearance and attitude of nine Winter Olympic robots. We have designed and modified dozens of times for their different functional forms, visual attitudes, and application scenarios. In the end, the Olympic Organizing Committee used the torch relay to be one of them. In addition to amphibious robots and underwater robots, there are also "intelligent shape" designs of flying robots, land six-wheel robots, climbing robots, ski robots, ice skating robots, curling robots and blind guide robots. It will be featured in the Winter Olympics ice and snow sports and the Winter Paralympic Games exhibition services, and will be applied to future life." Professor Xue said that each of these carefully designed and dressed intelligent robots has a different appearance and personality, and different application scenarios.

Zhang Yan, visedirektør for Beijing Municipal Commission of Urban Management, introduserte at for å ønske velkommen til vinter-OL i Beijing i 2022, er det 3 ikoniske landskap, 10 blomsterbed med tema, 620 landskapsskisser, 280,000 bur med belysning, 18,000 propagandaflagg og mer enn 60,000 steder. Kampanjebilder og 28 lysshow har blitt presentert over hele Beijing. Samtidig ble vårfestens landskapsskisser, røde flagg, fargerike flagg og tre{11}}innpakkete lykter arrangert i bakgatene og kommersielle blokkene.
Zhang Yan introduced that in the urban landscape design, attention was paid to the integration of elements of the Winter Olympics such as the emblem, mascot, ice and snow patterns, and folk elements of the Spring Festival, such as Chinese knots, lantern lighting, and Chinese zodiac characters. "For example, the huge Chinese knot in Tiananmen Square, 17 meters high, is the perfect presentation of the Chinese knot inlaid with the Olympic emblem."
Three iconic landscapes, including the emblem sculpture of Jinyuan Bridge in Shijingshan District, the "Haituo Tower" in Yanqing District and the emblem of the Beijing-Li Expressway slope protection, will also be applied for as Olympic heritage.
Zhang Yan specially introduced that the production process of the Winter Olympics landscape also adhered to the principles of "thrift, waste utilization, and environmental protection", and made full use of the original facilities and waste. For example, lanterns and Chinese knots are made of environmentally friendly materials, and the use of 3D printing technology not only saves costs, but also perfectly presents details. Landscape sketches and lightings all use energy-saving light sources; those coverings that add beautiful colors to the city in winter were originally discarded branches of colorful plants, but they have been rejuvenated by the creative use of urban designers.
