3D pahulje u cvjetnim gredicama Zimskih olimpijskih igara 3D ispisane su čvrstim gradskim otpadom
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.
Najveća pahulja ima promjer od 1,7 metara. U dizajnu i tiskanju treba uzeti u obzir debljinu, širinu, imitaciju i čvrstoću. Također je potrebno uzeti u obzir da 3D ispisani proizvod može nositi skrivene cjevovode i rebra za ojačanje.
It is reported that after the display of flower beds along Chang'an Avenue is over, the "snowflakes" will be recovered and recycled.
3D skeniranje-dizajn-3D ispis, kacige po mjeri za sportaše reprezentacije na snijegu
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.

Prosječna brzina motornih sanjki je oko 100 kilometara na sat, a maksimalna brzina može doseći 160 kilometara. Oduvijek je bio poznat kao F1 na ledu. Njegov brz-proces utrke može donijeti ljudima neusporedivo uzbudljivo osjetilno uživanje, što je najveća atrakcija utrka motornim sanjkama. U takvoj-brzini, sigurnost sportaša je glavni prioritet. Oprema za kacige važna je zaštitna oprema koja osigurava sigurnost sportaša na motornim sanjkama.
△ 3D scanning and printing exclusive helmet
Ranije su se kacige i oprema Nacionalne snježne reprezentacije uglavnom uvozile iz inozemstva, oslobađajući se ovisnosti o uvozu opreme i sudjelujući u natjecanju s kacigama koje su samostalno razvijene i dizajnirane u Kini.
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;
U ekskluzivnom načinu portretnog skeniranja, hrpa koja se trese ljudskom tijelu može se automatski ukloniti; tijekom skeniranja nisu potrebne točke lijepljenja, izvor svjetlosti je siguran i nevidljiv, a cijeli proces skeniranja je udoban i siguran;
Osim toga, njegova kombinirana tehnologija strukturiranog svjetla kreativno rješava problem teškog dobivanja podataka o kosi i oku, čineći podatke o glavi potpunijima.
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.
Koristeći China Aerospace T800 karbonska vlakna i materijale od čistih karbonskih vlakana, konačna težina kacige je 500 g lakša od prethodne generacije natjecateljskih kaciga, samo oko 1100 g, što učinkovito smanjuje težinu sportaša.
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 ispis za razvoj skijaškog robota
Nedavno je veliku pozornost privukao video skijaškog robota. U videu četveronožni-robot stupa na skiju, a s lijeve i desne strane su dvije grudve snijega. Ljuljajte se s jedne na drugu stranu i klizite prema dolje vrlo vješto, čini se da radnja premašuje razinu većine početnika.
Vrijedi napomenuti da se u dizajnu i proizvodnji skijaškog robota koristi tehnologija 3D printanja. Iz slike je vidljivo da su vanjska ljuska i poklopci udova skijaškog robota proizvedeni tehnologijom SLA 3D printanja, te se u kasnijoj fazi prskaju i boje. instaliran na robotu. Danas tehnologija 3D ispisa ima veliku učinkovitost i troškovne prednosti u proizvodnji kućišta za ovu vrstu robotskih proizvoda.

"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, zamjenik ravnatelja pekinške općinske komisije za upravljanje urbanim sredinama, predstavio je da za dobrodošlicu Zimskim olimpijskim igrama u Pekingu 2022. postoje 3 kultna krajolika, 10 tematskih cvjetnjaka, 620 skica krajolika, 280,000 kaveza rasvjete, 18,000 propagandnih zastava i više od 60,000 mjesta. Promotivne slike i 28 svjetlosnih emisija predstavljeni su diljem Pekinga. Istodobno, skice krajolika Proljetnog festivala, crvene zastave, šarene zastave i lampioni{11}}umotani drvećem bili su raspoređeni u stražnjim uličicama i komercijalnim blokovima.
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.
