Tecnica received second patent for its SLS print head

Leave a Comment

On September 6, 2016, the United Patent and Trademark Office granted patent number  9,435,998 to Tecnica for its laser print head system. This is the second patent granted this year by the USPTO to Tecnica for its 3D printing technology.

SLS 3d Printer by Tecnica

Casa 3d SLS Printer

The new technology, housed in the CASA SLS Printer and exhibited at the Inside 3D Expo at the Jacob Javits Center in April 2016 in NYC, will be released late December 2016.  Breaking away from a 30-year-old technology, Tecnica developed a printer that blows the competition away.  Tecnica fills the vast price void created by the other 3D printing companies by offering a professional grade SLS 3D printer at a starting price point below $20,000.  A powerful 25-watt laser with an internal cooling peltier system and a positive pressure airflow allows printing in a pre-set temperature range.      Read More

Galvo scanner for DMLS 3D printers

Abstract

Direct Metal Laser Sintering (DMLS) is a process in which metal powder is sintered by using laser energy without melting the metal.   The best way to describe sintering is by looking at a ball full of ice cubes in a room temperature and notice that the ice cubes are attached to each other, forming a large solid structure.

In the printing process of DMLS, one of the challenges is to move the laser beam over the bed surface printing area (X,Y). The printing of the X,Y surface is done either by line vector drawing or line raster drawing by moving the laser beam over a powder in a line pattern.  The Laser will turn the energy on, on the dots that need to be sintered and off in the spots that are to be cavities; as a result the area where the laser is off will keep the powder un-sintered while the spot that was heated by the laser will sinter and therefore attach bunch of small powder balls together.

3D Bed Leveling System

Fig. 1

At Tecnica we utilized our patented process for leveling of the print bed. The invention is based on transmitting light from the print head and analyzing the returned light from the print bed.  A light source (infrared LED) mounted and surrounded by Light detectors (photo transistors) is mounted next to the print . The light source emits light which is reflected back from the print bed.  Read More

3D printing to embellish security cameras

Leave a Comment

It’s pretty revolutionary to imagine that cameras can now camouflage and disappear into their environments and the home security company Kiwatch has pulled it off. The folks at Kiwatch have given their customers the option to 3D print their camera cases, allowing those customers to customize the color, pattern, and design of the camera’s case. You can choose between a wood imitation pattern or a cute monster that will blend into your child’s room.

3D printers bring new potential to prototyping and innovating at MIT Lincoln Laboratory
MIT Lincoln Laboratory staff are printing in a new dimension, using 3D printers to transform 3D designs into tangible objects. More formally known as additive manufacturing, 3D printing is a process that assembles conventional manufacturing materials, such as plastics and metals, in successive layers along the Z axis (i.e., top down or bottom up). The Laboratory has invested in several 3D printers, ranging in size and capability from industrial-scale, top-of-the-line models to desktop, home-hobbyist models. Located in the Rapid Hardware
