3D Printing with the Optima and CASA printers:
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. Read more..
Direct Metal Laser Sintering (DMLS) is a 3D printing process that uses additive manufacturing technology to produce metal prototypes and production parts. DMLS prints metal parts by sintering various metal and alloy particles together. Sintering is when small particles are bound to each other in a temperature that is lower than the melting temperature in the same way how ice cubes are bound to each other when put together without melting them first.
Due to the parameters of CNC machining, all features of complex geometry parts may not be machined. Features like cavities or undercuts may not be able to be machined in traditional CNC machining. Since the DMLS process sinters powdered metal together layer by layer, many complex features can now be produced.
The key to DMLS future is in rapid printing, strength and availability of material. The cost of a DMLS printer is too high to make it available to small and mid-size companies. Tecnica is introducing two lines of printers; Optima and CASA printers. The Optima 3D DMLS printer geared for metal printing while the CASA is a tabletop 3D printer geared for smaller and non metal parts. Both the Optima and the CASA using the Titan print-head SLS technology. The Optima printer prints in a resolution better than 0.07 mm over a print volume of 400 mm x 300 mm x 280 mm, making it the best printer for its class. The CASA printer prints in a resolution better than 0.07 mm over print size of 92x100x150 mm.
Tecnica’s improved the process in which the laser beam is controlled by incorporating hardware and software adjustments on the fly for the laser beam and bed position. This patented technology compensates for equipment deviations and takes into account environmental changes such as temperature, pressure, humidity and more.
Specifications for Optima:
- Feeding cartridge is used to handle multiple material.
- Prints material as Aluminum, Fe, Fe-0.8C, Fe-4Cu, Fe–0.8C–4Cu–0.4P 316L, M2 (tungsten–molybdenum), M35 ( tungsten–molybdenum-cobalt), Titanium, Nylon and more.
- The optima is using a high powered laser controlled by patented process surpassing printing speed by more than 4X of other 3D printers in the market.
- Saves print material by providing an option to chose your print bed ( 75x75x200 mm or 400x300x280 mm)
- By using a three case design and a removable print bed case, recycling of powder and retrieving of the printed models makes it easy and quick.
- The optima monitors oxygen, argon, powder, temperature, pressure at all times.
The CASA Desktop printer print volume is 92x92x150 mm and prints non metal material. Both the Optima and CASA printer use the Titan Print-head.
