Mcor Technologies Ltd is engaged in the design, development and manufacture of paper-based 3D printing systems. The company was founded in 2005 and is based in Dunleer, County Louth, Ireland. == History and technology == In 2003, Mcor founders Dr. Conor MacCormack and Fintan MacCormack developed paper 3D printing technology.〔Michael Wolf, Article in Forbes, ("3D Printing With Paper At Your Local Office Supply Store? Yep, If Mcor Has Its Way" ), "Forbes", March, 2013〕 This is unlike Laminated object manufacturing (LOM) technology, developed by Helisys Inc. (now Cubic Technologies).〔Article in Rapid Today, ("3D Printer Uses Standard Paper" ), "Rapid Today", May, 2008〕 Whereas LOM technology uses rolls of adhesive-coated paper and a knife or laser to cut a shape, paper 3D printing uses sheets of standard business A4 and letter paper, an adhesive dispensing system and a tungsten-tip blade to cut the shape.〔Article in Rapid Prototyping, ("LOM" ), "Rapid Prototyping", June 8, 2012〕〔Linda Bell, Article in NASA Tech Briefs ("Product of the Month: the IRIS Color 3D Printer" ), "NASA Tech Briefs", January 1, 2013〕 As in many other rapid prototyping processes, the part to be printed is built up from multiple thin cross sections of the 3D model created via computer aided design (CAD) software.〔Karlin Lillington, Article in The Irish Times ("Printer plots brave new 3D world" ), "Irish Times", July 7, 2008〕 After going a few years without official funding, in 2014, Mcor Technologies secured 2 rounds of venture funding which totaled $32 million, making it the largest amount raised by any 3D printing company that year. 〔PitchBook Data Inc., Article in Hot Topics ("Is Europe at the heart of 3D printing innovation? Here's why it may be" ), "Hot Topics", February, 2015〕 The process utilised by Mcor Technologies is as follows: # A sheet of paper is fed into the 3D printer. # A tungsten-tip blade cuts the desired geometry into the paper, also making a series of cross-hatch cuts in the area surrounding the part to facilitate support removal at the end of the process. # Drops of adhesive are dispensed on the paper (greater amounts within the boundaries of the shape and lesser amounts in the area that will become the disposable supporting material). # A new sheet of paper is fed into the printer. # The platform inside the printer raises to the top of the printer, applying pressure to the new sheet of paper and the prior sheet, fusing them together. # The platform lowers and the blade cuts the shape on the second sheet of paper, repeating this process until the shape is complete. # The solidified shape or part is manually separated from the surrounding paper. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mcor Technologies Ltd」の詳細全文を読む スポンサード リンク
