Solar Sinter: A Solar Powered 3D Printer for Making Glass Objects from Sand

According to the SLS (selective laser sintering),” this is one of the processes used by 3D printers.  The SLS process uses the powdered raw material such as plastic, glass, metal, ceramic.  A laser is directed at the powdered material to selectively fuse the material.  Layers of the fused material are created to form a 3D object.

Markus Kayser, a designer and researcher born in Germany used the idea behind the SLS technology to develop solar sinter, a 3D printer that uses sand as the powdered raw material and solar energy to produce glass objects.  Both solar energy and sand are available in abundance for free.  So once a solar sinter is made, an unlimited supply of 3D objects can be created for free.

The first solar sinter was manually operated and tested in the Moroccan desert in 2011.  A larger and fully-automated computer driven solar sinter was subsequently developed and tested in Egypt, near Sahara desert in 2012.  This is a brilliant and thought to provoke experiment”.  According to Markus Kayser, “The machine and the results of these first experiments presented here represent the initial significant steps towards what I envisage as a new solar-powered production tool of great potential.”:)

LUXeXcel: 3D Printing Functional Optical Components

According to the Conventional 3D printing techniques,” we are not able to 3D print functional optics.  These 3D printers may be able to 3D print transparent materials but fail to achieve optical properties such as surface roughness and scattering.  LUXeXcel, a company based in The Netherlands has developed print optical technology that can 3D print fully transparent, smooth and optically functional optical components such as lenses.

LUXeXcel uses a photopolymer material for 3D printing.  LUXeXcel created world’s first 3D printed reading glasses including the frames and the lenses for the Dutch Monarchs.  However, their services are not limited to the royalty but available to general public as well.  LUXeXcel’s website allows users to upload designs and order 3D printed optics.  The design can be uploaded in a variety of file formats and has to conform to their design guidelines.  They promise to 3D print a design within 5 working days of placing the order.  The print optical technology has used in automotive, medical, lighting, aerospace, and other industries”.:)
