This study covers the world outlook for 3D printers, materials, and parts across more than 190 countries. For each year reported, estimates are given for the latent demand, or potential industry earnings (P.I.E.), for the country in question (in millions of U.S. dollars), the percent share the country is of the region, and of the globe. These comparative benchmarks allow the reader to quickly gauge a country vis-à-vis others. Using econometric models which project fundamental economic dynamics within each country and across countries, latent demand estimates are created. This report does not discuss the specific players in the market serving the latent demand, nor specific details at the product level. The study also does not consider short-term cyclicalities that might affect realized sales. The study, therefore, is strategic in nature, taking an aggregate and long-run view, irrespective of the players or products involved. This study does not report actual sales data (which are simply unavailable, in a comparable or consistent manner in virtually all of the countries of the world). This study gives, however, my estimates for the worldwide latent demand, or the P.I.E., for 3D printers, materials, and parts. It also shows how the P.I.E. is divided across the world’s regional and national markets. For each country, I also show my estimates of how the P.I.E. grows over time (positive or negative growth). In order to make these estimates, a multi-stage methodology was employed that is often taught in courses on international strategic planning at graduate schools of business.
New bus shelters, built by a Shanghai company, feature a closed-loop design that looks like a rectangular frame, and which is 16ft 7in long, 4.ft 9in wide and 8ft 8in high. Placed along a country road in Fengjing town, the futuristic structures that come with original ink marks left on the surfaces, are believed to be the world’s first produced by 3D printers, says 3ders.org, a global news organisation dedicated to providing the latest news, trends and analysis in the 3D printing industry.
“All the printing materials are from recycled and classified industrial waste or tailings,” said Wang Aijuan, who is responsible for the 3D bus stop project at WinSun Construction Technologies. “The printing process is environmentally friendly, because such new technology does not produce additional waste.”
The company, which has been working on the development of 3D printing technology for the construction industry and related products for more than a decade, says 3D printing technology can save up to 60pc of building materials and 50 to 80pc of manpower, which greatly improves work efficiency and helps reduce costs.
“Normally it takes several days to build a bus stop, and traffic is blocked during the construction,” Ms Wang said. “However, it takes no more than an hour to set up a 3D bus stop at the side of the road, after printing and transport.”
“In addition, the 3D printed structures are five times stronger than those built in traditional ways,” she said.
The 3-D bus stop project has been launched as a pilot programme to demonstrate the practicality of this application for the potential 3D printing of future bus shelters, Ms Wang said. The company plans to promote the idea nationally and even globally, incorporating more functionality into the bus shelters, such as chairs, garbage cans and a small table.
Many industries and fields in China have embraced 3D printing technology for its high efficiency and ecological benefits. The value of output from the country’s 3D printing industry is expected to reach $7.68 billion (£5.47 billion), or one-third of the global market, by 2020, the China Industry Information Institute says.
As a specialist in 3D printed buildings, WinSun has attracted many headlines for its various 3D printed structures, such as 10 single-storey houses in Shanghai, a standalone villa in Suzhou, Jiangsu province, and 19 local government office buildings in Dubai.

The subjects – aged between six and 10 – suffer from a defect in one ear called microtia, which impacts its shape and function.
Scientists in China collected cartilage cells from the kids’ ears and grew new scaffolds based on 3D print-outs.
These were dotted with tiny holes, gradually filled out by the cells.
The tissue was then implanted into a skin flap to reconstruct the ear, a process that took several months.
The first child to go through the procedure two and a half years ago showed no signs the body had rejected the new cells.
Scientists will now monitor the kids for at least five years to determine the success of the project.
They will check whether the ears remain intact after the scaffold has broken down.
“Long-term follow-up of the cartilage properties and clinical outcomes…will be essential”
The researchers wrote: “We were able to successfully design, fabricate and regenerate patient-specific external ears.
“Nevertheless, further efforts remain necessary to eventually translate this prototype work into routine clinical practices.
“In the future, long-term follow-up of the cartilage properties and clinical outcomes…will be essential.”
The study was published this month in the journal EBioMedicine.
It shares similarities with the so-called ear mouse experiment in 1997, when a surgeon grafted cartilage onto the animal’s back.
Daily Star Online previously revealed a surgeon is working on a bionic vagina to help women with rare genetic conditions.
Guiness World Records has named a 3D printed graphene aerogel as “the least dense 3D printed structure”. The 3D printed graphene aerogel, developed by a Kansas State University, University at Buffalo and Lanzhou University (China) team, weighs 0.5 milligrams per cubic centimeter. This achievement will be featured in the GUINNESS WORLD RECORDS 2018 Edition.
The way the researchers print the three-dimensional graphene is also regarded as revolutionary. The researchers use a modified inkjet printer that uses two nozzles. They 3D print droplets of a graphene oxide and water mixture in a freezer on a cold plate that is minus 20 degrees Celsius. This method creates a 3D ice structure of graphene and frozen water, which helps the graphene to maintain its shape.
When printing is complete, the researchers place the 3D material in a freeze dryer, which removes the ice by providing high vacuum and low temperature. What’s left is a three-dimensional graphene aerogel that maintains its shape at room temperature.
This new printing method is seen as an improvement over existing ones because it uses fewer ingredients and only requires graphene oxide and frozen water. Additionally, the two nozzles on the modified printer enable the researchers to create complex shapes with less material, which makes it the lightest material in the world. “With this 3-D printing method, we can control the shape of the graphene aerogel and ideally, we can control the electric and mechanical properties for the aerogels, too,” the team said.
