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 salji terbesar mempunyai diameter 1.7 meter. Dalam reka bentuk dan percetakan, ketebalan, lebar, tiruan dan kekukuhan harus dipertimbangkan. Ia juga perlu mempertimbangkan bahawa produk bercetak 3D boleh membawa saluran paip tersembunyi dan tulang rusuk pengukuhan.
It is reported that after the display of flower beds along Chang'an Avenue is over, the "snowflakes" will be recovered and recycled.

Proses perlumbaan pantas-nya boleh membawa orang ramai keseronokan deria yang sangat menarik, yang merupakan tarikan terbesar perlumbaan kereta salji. Dalam keadaan kelajuan-sebegitu tinggi, keselamatan atlit adalah keutamaan. Peralatan topi keledar adalah peralatan perlindungan yang penting untuk memastikan keselamatan atlet kereta salji.

△ 3D scanning and printing exclusive helmet
Sebelum ini, topi keledar dan peralatan Pasukan Salji Kebangsaan kebanyakannya diimport dari luar negara, menghilangkan pergantungan kepada import peralatan dan menyertai pertandingan dengan topi keledar dibangunkan dan direka secara bebas 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 mod eksklusif pengimbasan potret, timbunan goncang tubuh manusia boleh dialih keluar secara automatik; tiada titik melekat diperlukan semasa pengimbasan, sumber cahaya selamat dan tidak kelihatan, dan keseluruhan proses pengimbasan adalah selesa dan selamat;
Selain itu, gabungan teknologi cahaya berstruktur tatasusunannya secara kreatif menyelesaikan masalah pemerolehan data rambut dan mata yang sukar, menjadikan 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 gentian karbon China Aerospace T800 dan bahan gentian karbon tulen, berat topi keledar akhir adalah 500g lebih ringan daripada topi keledar pertandingan generasi sebelumnya, hanya kira-kira 1100g, yang mengurangkan berat badan atlet dengan berkesan.
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.

Percetakan 3D untuk membangunkan robot ski
Baru-baru ini, video robot ski telah menarik perhatian ramai. Dalam video, robot berkaki empat-memijak ski dan terdapat dua bola salji di sebelah kiri dan kanan. Ayun sisi ke sisi dan luncurkan ke bawah dengan sangat mahir, aksi itu nampaknya melebihi tahap kebanyakan pemula.

Perlu diingat bahawa teknologi percetakan 3D digunakan dalam reka bentuk dan pembuatan robot ski. Ia boleh dilihat dari rajah bahawa cangkerang luar dan penutup anggota robot ski dihasilkan oleh teknologi percetakan 3D SLA, dan disembur dan diwarnakan pada peringkat kemudian. dipasang pada robot. Hari ini, teknologi percetakan 3D mempunyai kecekapan dan kelebihan kos yang hebat dalam pembuatan perumah untuk jenis produk robotik 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.
