Kepingan salju 3D di hamparan bunga Olimpiade Musim Dingin dicetak 3D dengan sampah padat perkotaan
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.
Kepingan salju terbesar memiliki diameter 1,7 meter. Dalam desain dan pencetakan, ketebalan, lebar, imitasi dan kekokohan harus dipertimbangkan. Penting juga untuk mempertimbangkan bahwa produk cetak 3D dapat membawa saluran pipa tersembunyi dan tulang rusuk penguat.
It is reported that after the display of flower beds along Chang'an Avenue is over, the "snowflakes" will be recovered and recycled.

Kecepatan rata-rata mobil salju sekitar 100 kilometer per jam, dan kecepatan maksimumnya bisa mencapai 160 kilometer. Itu selalu dikenal sebagai F1 di atas es. Proses balapnya yang-cepat dapat menghadirkan kenikmatan sensorik yang tak tertandingi bagi orang-orang, yang merupakan daya tarik terbesar dari balap mobil salju. Dalam keadaan-kecepatan tinggi seperti itu, keselamatan atlet adalah prioritas utama. Perlengkapan helm merupakan alat pelindung yang penting untuk menjamin keselamatan atlet snowmobile.
△ 3D scanning and printing exclusive helmet
Sebelumnya, helm dan perlengkapan Tim Salju Nasional sebagian besar didatangkan dari luar negeri, menghilangkan ketergantungan impor perlengkapan dan mengikuti kompetisi dengan helm yang dikembangkan dan didesain secara mandiri di China.
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;
Dalam mode eksklusif pemindaian potret, tumpukan goyangan tubuh manusia dapat dihapus secara otomatis; tidak ada titik lengket yang diperlukan selama pemindaian, sumber cahaya aman dan tidak terlihat, dan seluruh proses pemindaian nyaman dan aman;
Selain itu, teknologi cahaya terstruktur array gabungannya secara kreatif memecahkan masalah akuisisi data rambut dan mata yang sulit, membuat data kepala lebih lengkap.
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.
Menggunakan serat karbon China Aerospace T800 dan bahan serat karbon murni, berat helm akhir 500g lebih ringan dari helm kompetisi generasi sebelumnya, hanya sekitar 1100g, yang secara efektif mengurangi berat atlet.
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.
Pencetakan 3D untuk mengembangkan robot ski
Baru-baru ini, sebuah video robot ski telah menarik banyak perhatian. Dalam video tersebut, robot berkaki empat-menginjak ski, dan ada dua bola salju di sisi kiri dan kanan. Ayunkan sisi ke sisi dan geser ke bawah dengan sangat terampil, aksinya tampaknya melebihi level kebanyakan pemula.
Perlu dicatat bahwa teknologi pencetakan 3D digunakan dalam desain dan pembuatan robot ski. Dapat dilihat dari gambar bahwa kulit luar dan penutup kaki robot ski diproduksi dengan teknologi pencetakan 3D SLA, dan disemprot dan diwarnai pada tahap selanjutnya. dipasang di robot. Saat ini, teknologi pencetakan 3D memiliki efisiensi dan keuntungan biaya yang besar dalam pembuatan rumah untuk jenis produk robot ini.
△ 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, wakil direktur Komisi Manajemen Kota Kota Beijing, memperkenalkan bahwa untuk menyambut Olimpiade Musim Dingin Beijing 2022, ada 3 lanskap ikonik, 10 petak bunga bertema, 620 sketsa lanskap, 280,000 kandang pencahayaan, 18,000 bendera propaganda, dan lebih dari 60,000 tempat. Gambar promosi dan 28 pertunjukan cahaya telah dipresentasikan di seluruh Beijing. Pada saat yang sama, sketsa lanskap Festival Musim Semi, bendera merah, bendera warna-warni, dan lentera yang dibungkus -pohon diatur di gang belakang dan blok komersial.
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.
