An 83 year old inventor of the Lyman Filament Extruder II, Hugh Lyman, who in 1976 wrote in The Computerworld magazine about IBM 5100, an early 55 lb “portable computer” may have solved a major source of expense for those interested in 3D printing. The 3D printer has been called “The emerging gadget which may very well change everything” by Time Magazine in 2013. A desk-top model of the 3D printer may be available for $500.00.
Answering a call for an invention that would solve the problem of expensive filaments required for 3D printing, Hugh Lyman submitted two entries. More than 12,000 3D printing enthusiasts from around the world have already downloaded the plans of his two extruders. Atleast one 3D company Lulzbot, plans to sell a pre-assembled version. The second entry is a cheaper to make and use version, and won the $40,000 Inventables award, set up by Zach Kaplan, CEO of Inventables. Click here to see Time Magazine’s video on how the Lyman’s winning extruder works, photos of Hugh Lyman, Zach Kaplan, and Lyman’s two entries, with an excellent article on the inventor. The two plans are:
1) First entry – Lyman Filament Extruder which can turn pellets into filaments but costs more than $250.00
2) Second and winning entry – Lyman Filament Extruder II, with a few of the parts changed from the first design entry to be prized under $250.00; the judges agreed that he was the winning inventor of the “Desktop Factory Competition”.
