3D Printintg History

Have you ever think when 3D printing technology has been developed ?
Nice story taken from below:

October 5, 2011 - Roland DG Corporation introduced the new iModela iM-01.
Sep, 2011 - Vienna University of Technology, a smaller, lighter and cheaper printing device has now been developed.
This smallest 3D printer weighs 1.5 kilograms, it costs around 1200 Euros.
Aug, 2011 - The world’s first 3D printed aircraft created by Engineers at the University of Southampton.
Jul, 2011 - Led by the University of Exeter, the University of Brunel and application developer Delcam, researchers in UK have presented the world's first 3D chocolate printer.
June 6. 2011 Shapeways and Continuum Fashion announced the first 3d printed bikini.
Jan, 2011 - Dutch 3D Printer manufacturer Ultimaker raised300 mm/second and the travel rate to 350 mm/second.
Jan, 2011 - Researchers at Cornell University began to build 3D food printer.
Dec. 8, 2010 - Organovo, Inc., a regenerative medicine company focused on bioprinting technology, announced the release of data on the first fully bioprinted blood vessels.
Nov, 2010 - Urbee is the first prototype car is presented. This is the first car ever to have its entire body printed out on a giant 3D printer. All exterior components - including the glass panel prototypes - were created using Dimension 3D Printers and Fortus 3D Production Systems at Stratasys' digital manufacturing service - RedEye on Demand.
2008 - Objet Geometries Ltd. announced that its revolutionary Connex500™ rapid prototyping system to be the first-ever system enabling the manufacture of 3-D parts using several different materials at the same time.
2008 - The first version of Reprap was released. It can manufacture about 50 percent of its own parts.
2006 - An open source project is initiated - Reprap - which was aimed at developing a self-replicating 3D printer. You can redistribute it and/or modify it under the terms of the GNU General Public Licence.
2005 - Z Corp. launched Spectrum Z510. It was the first high definition color 3D Printer in the market.

1997 - EOS sold its stereolithography business to 3-D Systems but remains the largest European producer.
1996 - 3D Systems introduced "Actua 2100". The term "3D Printer" was first used to refer rapid prototyping machines.
1996 - Z Corporation introduced "Z402".
1996 - Stratasys introduced "Genisys".
1995 - Z Corporation obtained an exclusive license from MIT to use the technology and started developing 3D Printers based on 3DP technology.
1993 - Massachusetts Institute of Technology (MIT) patented "3 Dimensional Printing techniques". It is similar to the inkjet technology used in 2D Printers.
1993 - Solidscape was founded to produces an inkjet-based machine that can build small parts with excellent surface finish at a relatively slow rate.
1992 - DTM sold its first selective laser sintering (SLS) system.
1992 - Stratasys sold its first FDM-based machine "3D Modeler".
1991 - Helisys sold its first laminated object manufacturing (LOM) system.
1989 - Scott Crump founded Stratasys.
1988 - Scott Crump invented Fused Deposition Modeling (FDM).
1988 - 3D Systems developed model SLA-250, which was the first version to the general public.
1986 - Charles Hull founded 3D Systems and developed the first commercial 3D Printing machine, it was called as Stereolithography Apparatus.
1986 - Charles Hull named the technique as Stereolithography and obtained a patent.
1984 - Charles Hull developed the technology for printing physical 3D objects from digital data.

3D Printing and Software Engineering

What 3D Printing and Software Engineering disciplines have in common ?

One of the latest revolutions in software engineering is Model Based Development. It simply means to use diagrams instead of code, create model and just generate code. Such approach decrease number of engineers involved, shorten communication path, in consequence reduce number of errors and total development cost.

3D Printing technology will bring the same change to the other industries with all the andventages mentioned above. Because it is just Model Based Development - you design, evaluate, test you work in the virtual 3D environment, and create it immediately from it by printing.

The change is ongoing...

Hotend - lathe needed


On the way towards exploring 3d printing technology, lack of havy tools like lathe is problematic. In order to transform problem in to the challenge, mini lathe has been designed and build.

Basic parameters

  • Chunk max diameter 45mm
  • Spindle internal diameter 8mm
  • Lathe size 40x20cm
  • Motor 300W, 24v
  • Material - mostly Alloy PA6
