Typically used for surgical tools, the 6-axis laser micro-machining center is designed for laser cutting small-diameter parts in complex configurations.
An entirely servo-controlled translation axes architecture achieves constant velocity and cutting conditions throughout a range of operating conditions, enabling 24/7 operations. The granite-structure-based motion subsystem offers long-term stability and precision.
A 300W, high-stability, SPI fiber laser is integrated and delivered by fine kerf optics, operating in CDRH Class 1 mode.
The machine is equipped with an automated access door, light curtain, and high-efficiency particulate air (HEPA) filtered exhaust system for gas and debris removal. An automated location gaging system enables fast loading by an operator or robot.
Machine operation is based on a Windows-based CNC digital servo control with G&M-code RS-274 capability nuFace with operator and engineering mode for continuous machine control and monitoring functions.

Exact Metrology named Midwest dealer for EnvisionTEC
Exact Metrology is now the greater Midwest dealer for EnvisionTEC, a Detroit, Michigan-based manufacturer supplying 3D printers and materials to a variety of industries. Exact Metrology offers portable scanning and measurement technologies, contract measurement for 2D and 3D laser scanning services, reverse engineering services, non-contact inspection, metrology services, 3D digitizing and training, long-range scanning, and CT scanning services.
“The addition of EnvisionTEC brings our line to a new level of technology,” says Dean Solberg, co-president of Exact. “It made perfect sense to extend our equipment lines into 3D printing and we were most impressed with the EnvisionTEC line and the company’s commitment to growth.”
Wire EDMs for automation
The CUT P series of wire EDMs – 350/550/800/1250 – offer efficient power generators, intuitive human- machine interfaces (HMIs), and several automation options for lights-out operation. Featuring Intelligent Power Generator (IPG) technology, the machines offer surface finishes to Ra 0.08µm and boost cutting speeds by up to 20%.
Fixed tables provide rigidity and stability to ensure accuracy when machining heavy workpieces, and integrated regulation systems maintain temperatures within ±0.2°C for repeatability. In shops where the ambient temperature may vary throughout the day, a thermostability option provides temperature control protection.
Collision protection technology in the X-, Y-, U-, V-, and Z-axis, prevent potential machine damage and eliminate downtime and maintenance – even at maximum axis travel speeds of 3m/min.
The Windows 7-based AC CUT HMI 2 user interface simplifies file management and maximizes operator efficiency, supporting intuitive programming directly on the control.

Laser beam profiling camera
The Ophir Pyrocam IV USB laser beam profiling camera features a 320 x 320 pixel pyroelectric array that can profile beams up to 1" (25mm) without reduction optics. Measuring pulsed- and continuous-wave (CW) lasers, from 13nm to 355nm and 1.06µm to >3,000µm, the Pyrocam IV device includes an integral focal plane chopper for CW beams and thermal imaging. The plug-and-play USB3.0 interface can be connected to a PC for further analysis of the beam.
Series 800 2-to-6-layer extrusion tooling produces high quality, material- efficient 1/8" to 6" OD tubing. The redesigned series produces smooth extrusion and layer definition of fluropolymer andother materials for all multi-layer, multi-lumen medical tubing. The design further allows thin layer combinations of polymers and adhesives to 0.02mm or less.

Diagnosing urinary tract infections (UTIs) could be accelerated with an autonomous sensor technology being developed at Purdue University.
“Current testing relies on time-consuming and costly urine culture tests performed at medical facilities and on at-home testing using store-purchased dipsticks that generally have high false-alarm rates,” says Babak Ziaie, professor of electrical and computer engineering in Purdue’s School of Electrical and Computer Engineering. “Collecting urine samples for these methods can be challenging for infants and geriatric patients who suffer from neurodegenerative diseases. There’s also a privacy and dignity issue.”
Developed by Purdue researchers, a bandage-sized, disposable UTI sensor module with a urine-powered battery can be embedded in a diaper. When exposed to urine, the battery provides power to the sensor circuitry. The sensor checks for nitrites, chemical compounds commonly associated with UTIs, and wirelessly sends the result to a smartphone app. The app keeps a data log and sends the results to the patient, caregiver, and/or health-care network if required.
Several patents exist on similar technologies. However, Purdue’s sensor is the only one that works fully autonomously, with conventional methods requiring a certain level of patient or caregiver intervention.
A prototype tested with synthetic urine samples has shown to be more accurate than commercial dipsticks.
“Once you detect a UTI in its early stage, it’s very easy to cure,” says Byunghoo Jung, associate professor of electrical and computer engineering in the School of Electrical and Computer Engineering. “You just need an antibiotic. Early detection is the key.”
The autonomous feature of the technology alert patients who might not be aware of the symptoms of UTIs or the need to check for them. In such cases, UTIs are difficult to detect in their early stages.
The autonomous system can regularly check UTIs – improving accuracy due to the amount of data collected. It can also track UTI status through time.
Work is now shifting to sizing, packaging, diaper-embedding methods, smartphone app details, and other efforts to prepare the technology for commercialization. A pilot study also is planned.
Researchers are seeking interested companies to license the technology, which is patented through the Purdue Office of Technology Commercialization.
