Apis Cor are the first company to develop a mobile construction 3D printer which is capable of printing whole buildings completely on site.Also we are people. Engineers, managers, builders and inventors sharing one common idea – to change the construction industry so that millions of people will have an opportunity to improve their living conditions.On the six continents of Earth there are families which cannot afford to buy or build a house. A good accommodation is costly. And waiting for it to get construction takes more than a single month.So it used to be. Today – it’s different.Today we have a 3D printing technology, new building materials and a mobile 3D printer to build affordable, eco-friendly houses within a single day, capable of lasting up to 175 years

The ability to pattern planar and freestanding 3D metallic architectures at the microscale would enable myriad applications, including flexible electronics, displays, sensors, and electrically small antennas. A 3D printing method is introduced that combines direct ink writing with a focused laser that locally anneals printed metallic features “on-the-fly.” To optimize the nozzle-to-laser separation distance, the heat transfer along the printed silver wire is modeled as a function of printing speed, laser intensity, and pulse duration. Laser-assisted direct ink writing is used to pattern highly conductive, ductile metallic interconnects, springs, and freestanding spiral architectures on flexible and rigid substrates.

A team of Northwestern University engineers has created a new way to print three-dimensional metallic objects using rust and metal powders.

While current methods rely on vast metal powder beds and expensive lasers or electron beams, Northwestern’s new technique uses liquid inks and common furnaces, resulting in a cheaper, faster, and more uniform process. The Northwestern team also demonstrated that the new method works for an extensive variety of metals, metal mixtures, alloys, and metal oxides and compounds.

Because ceramics cannot be cast or machined easily, three-dimensional (3D) printing enables a big leap in geometrical flexibility. We report preceramic monomers that are cured with ultraviolet light in a stereolithography 3D printer or through a patterned mask, forming 3D polymer structures that can have complex shape and cellular architecture. These polymer structures can be pyrolyzed to a ceramic with uniform shrinkage and virtually no porosity. Silicon oxycarbide microlattice and honeycomb cellular materials fabricated with this approach exhibit higher strength than ceramic foams of similar density. Additive manufacturing of such materials is of interest for propulsion components, thermal protection systems, porous burners, microelectromechanical systems, and electronic device packaging.

We introduce a technique for 3D printing soft strands, fibers, and bristles using conventional 3D printers. Our work was inspired by the phenomenon that occurs during the operation of a handheld glue gun: when a person extrudes hot glue material and moves the gun away, a “string” of residue often forms unintentionally. The shape, length, and thickness of the resulting stringy material varies based on how much glue was extruded and how fast the user moves away from the extrusion point. This artifact often annoys users, but in this work, we exploit the phenomenon.

Chinese company WinSun Decoration Design Engineering Co has expanded the capabilities of 3D printing. After constructing ten houses in under twenty-four hours last year, now they are back with both the world’s tallest 3D printed building – a five-story apartment block – and a 1,100 square meter mansion with internal and external decoration to boot.

A pioneering 3D-printed house just popped up in Xian, China – and Chinese company ZhuoDa “built” the two-story villa in less than three hours. Made up of six 3D-printed modules, the house was assembled like LEGO bricks before a live audience who were then invited to explore the interior. The modular fireproof home can withstand a magnitude-9 earthquake and is made from a special construction material the company is keeping secret.

Of course the printing itself took a lot longer, but no figures on how long that was!

a team of researchers at UNIST has announced that they have developed a high-resolution 3D printing technology that is capable of printing electronic circuits on plastic, metallic or magnetic nanoparticles that are curved and much flexible. According to the team, led by Prof. Jang-Ung Park (School of Materials Science and Engineering), they have succeeded in imprinting ultra-fine 3D patterns that are as small as 0.001 mm in size. This is thinner than a red blood cell.

The Continuous Liquid Interface Productiongo technology (CLIP) process relies on a special transparent and permeable window which allows both light and oxygen to get through. Think of it as a large contact lens. The machine then is able to control the exact amount of oxygen and when that oxygen is permitted into the resin pool. The oxygen thus acts to inhibit the resin from curing in certain areas as the light cures those areas not exposed to the oxygen. Thus the oxygen is able to create a ‘dead zone’ aa4within the resin which is as small as tens of microns thick (about the diameter of 2-3 red blood cells). In this subsection of the resin, it is literally impossible for photopolymerization to take place. The machine will then produce a series of cross sectional images using UV light in a fashion similar to playing a movie.

Using inexpensive glass beads traditionally used for reflective pavement markings at airports, the PNNL team has demonstrated 1000x magnification, which is necessary to see tiny anthrax spores and plague cells. They have also made a 350x version, which is adequate to identify parasites in blood samples or protozoa in drinking water. A 100x version enables children to investigate common items like salt grains and flower petals in much greater detail.
