Le marché de l'impression 3D a connu une croissance exponentielle au cours des dernières années. De nombreuses entreprises entrent sur le marché des imprimantes 3D pour des usages domestiques avec des prix toujours plus compétitifs. Etant donné que même les meilleures imprimantes 3D produisent des objets sur lesquels les couches de matériau sont bien visibles, un travail de finition est toujours nécessaire. Après cette procédure, l'objet imprimé est complètement imperméable et est livré avec une surface lisse.
Despite the buzz around 3D Printing, VCs sat on the sidelines through most of 2012. MakerBot’s acquisition by Stratasys (deal value of $403M which could climb to $603 million with performance earnouts) was one of the highlights in 2013 which also saw VCs come around to 3D printing. Funding growth YoY stood at 319% and deals also grew by nearly 88% in the same 12 month period.
"A esta chica le faltaba todo este trozo de hueso", dice el doctor Mikel Sánchez. En su mano no tiene la fotografía de la paciente, ni la imagen en 2D de su radiografía o un TAC, sino una reproducción a escala de sus propios huesos en plástico, con todas sus articulaciones. "La diferencia entre la reconstrucción de la imagen en 3D y la pieza de la zona afectada en 3D es que te permite ensayar cómo vas a intervenir, incluso reconducir el tratamiento y no operar porque ves perfectamente que se puede recuperar de otra manera, y para el paciente se acorta sustancialmente el tiempo de recuperación".
One day, in the not-too-distant future, you’ll be able to walk into a car dealership, choose a design — including the number of seats — and have a 3D printed car by the end of the day.
This is Jay Rogers’ vision. Rogers is the CEO of Local Motors, the company that just built the world's first 3D printed car known as the Strati. The electric, pint-sized two-seater was officially unveiled last week at the International Manufacturing Technology Show (IMTS) in Chicago, Illinois.
“Telsa made the electric drive train famous, we’re changing the whole car,” Rogers told Mashable, clearly still relishing his community-based design and his company’s moment in the 3D manufacturing sun.
Some M&A activity afoot in the world of hardware design: GrabCAD, an online community that has been described as the ‘Github for mechanical engineers’, is getting acquired by 3D printing giant Stratasys, a source tells us. The companies plan to announce the deal a little later today [Update: confirmed]. We have heard that the deal is in the region of nine figures, and around $100 million.
History will be made when the world’s first 3D-printed car drives out of McCormick Place in Chicago, Ill. During the six-day IMTS – The International Manufacturing Technology Show 2014, the vehicle will be printed over 44 hours then rapidly assembled by a team led by Local Motors with the historic first drive set to take place the morning of Saturday, September 13.
Called the Strati, the vehicle will be 3D printed in one piece using direct digital manufacturing (DDM), which is the first time this method has been used to make a car. Mechanical components, like battery, motor, wiring, and suspension, are sourced from a variety of suppliers, including Renault’s Twizy, a line of electric-powered city cars.
L'impression 3D suscite depuis plusieurs années un intérêt croissant chez les industriels, les passionnés de technologie et les chercheurs. L'hypermédiatisation qui accompagne la baisse accélérée des prix des imprimantes 3D destinées au consommateur pourrait méprendre sur l'origine du procédé. Les premières expériences remontent aux années 1960, les pionniers Charles Hull [1] et Scott Crump [2] (les fondateurs respectifs de deux leaders mondiaux actuels du secteur, 3D Systems Corp. [3] et Stratasys [4]) ayant alors déposés les premiers brevets. L'impression tridimensionnelle est en réalité un terme chapeau recouvrant plusieurs types de technologies, la stéréolithographie et le frittage sélectif par laser étant les plus courants.
Engineers at the Italian aerospace company Avio have developed a breakthrough process for 3D printing light-weight metal blades for jet engine turbines.
The method builds the blades from a titanium powder fused with a beam of electrons accelerated by a 3-kilowatt electron gun.
The gun is 10 times more powerful than laser beams currently used for printing metal parts. This boost in power allows Avio, which is part of GE Aviation, to build blades from layers of powder that are more than four times thicker than those used by laser-powered 3D printers.
