The World’s First 3D Printed Meeting Space

Not Your Typical Meeting Space

If you are somewhere in Amsterdam and looking for a meeting place, we know just where you can find one. And it’s totally 3D printed. The building will be called De Vergaderfabriek, Dutch for “the Meeting Factory.” The structure is 1,000-square-foot but was originally supposed to be bigger and taller. It isn’t ready yet for occupancy, but it will be soon.

The Meeting Factory is located near a small airport and was designed to look like the rotating blades of a jet engine. The walls are curved to create a sense of equality and safety that will enhance communication. Those who will use the room or the “tent’ as they like to call it, will be able to choose from different 360-degree video projections set to their specified music. It’s not going to be a room with bare walls. There will be 12 ribbed walls in total.

The builders created a specific type of mortar that hardens within a day and that won’t shrink, expand, or collapse. They developed special algorithms to the double-curved walls, pre-researched to determine if they were feasible.

Those who operated the printer, controller, and mixing device were deep in concentration as they have only one chance to get it right. They prepared and checked everything – the temperature, the consistency of the material, the location of the wall, the electricity and water – before they finally press the button to go. There were many regulations to hurdle in order that a structure, just a hundred square meters in size, would be built.

How long did the construction of the Meeting Factory take? It was expected to take 10 days but it took a few more days longer. It is expected to finish imminently. It wasn’t the goal to do it as fast as possible. It was more important to do it right. In any case, the whole process will be much faster and cheaper next time. Several houses are set to be 3D-printed later this year in the Dutch city of Eindhoven, and the creators of the Meeting Factory believe 3D printing will become a reasonably standard building method within a short time.

3D Printing: Golden Age in Materials, Processes and Buildings

3D Printing Material: More Than Plastic

Researchers and innovators around the world keep coming up with opportunities and discoveries in 3D printing making the technology brand new when it’s actually decades old. Out of imagination and creativity, people experiment with new materials, developed processes to create objects previously impossible to print, and come out with new building typologies. Where materials are concerned majority of print material used is still plastic.

However, a product designer from the Netherlands have developed a method using wet paper fibers which are stronger and durable than regular paper. It uses a natural binding agent and is recyclable.

Steel is also the next promising material. The world’s first 3D-printed stainless steel bridge was announced at Dutch Design Week in October of 2018 by a robotics company. The Iowa State University developed a 3D-printed ceramic facade that can be integrated with a building’s mechanical system to control light, airflow, and privacy, also providing evaporative cooling benefits.

Another material is glass, considered even dangerous to work within 3D printing, involving heating the glass to 1,000 degrees Celsius resulting to coarse-textured products. The German Karlsruhe Institute of Technology used a standard 3D printer to produce liquid glass. The acrylic solution had dispersed silica in it and when the object was printed ultraviolet light hardened the material. It was then exposed to high temperatures and as the material burned away, the silica particles fused into smooth, transparent glass.

The internal and external structure of materials like wood have been developed at New York’s Columbia University using a scanning technique combined with 3D printing. An actual wood block was used as a guide to create the model that was first sliced at exact intervals; the images then made by these slices were prepared for 3D printing. The meaning of this success is that other objects with complex internal structures can be 3D-printed. Concrete is another material worth mentioning. The U.S. Marine Corps recently created the world’s first 3D-printed concrete barracks, all of 500-square- foot barracks in 40 hours.

An Italian company WASP has created a 3D-printed house from natural materials in the surrounding area – namely earth and the waste products from rice production. A large-scale 3D printer was used. It has just a few wooden components, took 100 hours to build and has no ecological impact.

Largest 3D Printed Bridge Over Shanghai

Modern Takes Ancient Inspiration

Across the Shanghai Wisdom Bay Pond spans the the world’s longest pedestrian bridge that’s 3D-printed.It’s a single-arch bridge designed and developed by Professor Xu Weiguo from the Tsinghua University (School of Architecture) – Zoina Land Joint Research Center for Digital Architecture. It measures 26.3 meters long and 3.6 meters wide, similar and inspired by the ancient Anji Bridge in Zhaoxian, China.

The structure created used a 3D printing concrete system integrated digital design, cost efficiency, smart technology, and architectural dynamism. The bridge’s handrails are shaped like flowing ribbons on the arch, creating a light, elegant movement across the pond. Made out of 44 hollowed-out 3D-printed concrete units and the handrails are divided into 68 units. The bridge’s components have been printed from composite materials, containing polyethylene fiber concrete to match the structural performance of conventional materials.

The scale of the physical model of the bridge is 1:4 which aims to prove that the bridge could hold all the pedestrians on the entire bridge surface. On actual construction, two robots printed the concrete components over the course of 450 hours. No templates nor reinforcing bars were used which contributed to 33% savings compared to the conventional process of construction. Additionally, there’s a monitoring system installed in the bridge that gives data drawn from vibrations of the stresses and the strains in the embedded wires.

The information gathered will allow for a greater understanding of the practical performance of new concrete materials, and the structural properties of 3D-printed components.

3D printing technology has brought about major changes in the use of concrete as printing material, but it’s not the only material. Columbia University has developed a new technique for 3D printing and scanning, producing a product with the look of timber, having authentic interior grain. Meanwhile, the world’s first 3D-printed steel bridge was recently unveiled at Dutch Design Week.

3D Printing Technology: Advances To Expect in 2019

3D Printing Technology: Slowly But Surely

According to Paul Benning, Senior Fellow and Chief Technologist, 3D Printing, at HP Inc. (Palo Alto, CA), 3D printing technology, also known as additive manufacturing, has made significant, though incremental, strides in the last couple of years. He cites areas that remain challenges: material properties and seamless integration of 3D printing in the larger manufacturing environment.

The design process will get a boost from generative design. Generative design will automate the process by looking ahead at the design intent and suggests ways to fill in the design. Over time, engineers will be able to input the requirements of a part and a system that will spring up with lots of design variations until it evolves into the most lightweight and efficient design possible. Other production techniques cannot create designs and geometries like 3D printing can by using generative design.

Bioprinting

Bioprinting has made considerable advances in the past couple of years, but it is more than printed organs that can be transplanted into patients. Printing small, viable tissues, collections of cells that communicate with each other are the gists of bioprinting, not large organs. For example, testing a new drug with its basic small molecule interaction up to target molecules, then to cellular interactions. The richness of that environment gives R&D teams a much better system to study without having to do live animal studies.

We are not yet there in terms of livers and kidneys or other functional organs, but simpler tissues like cartilage and sections of bladder have been printed and transplanted into animals successfully. More relevant today are biocompatible materials for implantable applications, hearing aids, patient devices.

3D printing advances in functional color parts are becoming mainstream. It’s not only for aesthetics but, it also enables putting assembly instructions or wear indicators on a part, like UPC symbols or digital serial numbers on every single part. It helps track production from raw materials to end of life.

The industry has the core 3D-printing technologies – Multi Jet Fusion, selective laser sintering, stereo- lithography and binder jet additive manufacturing which will drive growth in bringing 3D-printed metal parts to the market. Likewise, the cost factors for 3D printing – runs of thousands to tens of thousands of parts – are economically advantageous, making 3D technology a much more productive and valuable part of the manufacturing ecosystem.
