March U.S. cutting tool consumption totaled $200.05 million according to the U.S. Cutting Tool Institute (USCTI) and AMT – The Association For Manufacturing Technology. This total, as reported by companies participating in the Cutting Tool Market Report (CTMR) collaboration, was up 14.3% from February’s $174.98 million and up 8.4% when compared with the total of $184.57 million reported for March 2016. With a year-to-date total of $548.08 million, 2017 is up 5.9% when compared with 2016.

These numbers and all data in this report are based on the totals reported by the companies participating in the CTMR program. The totals here represent the majority of the U.S. market for cutting tools.

“The cutting tool industry reported numbers are supporting the positive feelings that exist in the Domestic Market,” says Brad Lawton, Chairman of AMT’s cutting tool product group. “This is a very welcome improvement and support for the Trump Administration’s pro manufacturing policies”

Johan Israelsson, president of Sandvik Hyperion adds, “It is clear that there is a much stronger customer demand across all sectors of the global market that we serve. Although there is some tendency to rebuild inventories as one driver, we are also experiencing an underlying market growth. It is especially encouraging to see optimism within the oil and gas industry after a very difficult period.”

Stratasys Ltd. has unveiled the Stratasys Continuous Build 3D Demonstrator. The new platform is composed of a modular unit with multiple 3D print cells working simultaneously and driven by a central, cloud-based architecture. To set new standards in additive manufacturing (AM) throughput, the Stratasys Continuous Build 3D Demonstrator is designed to produce parts in a continuous stream with only minor operator intervention, automatically ejecting completed parts and commencing new ones.

Each 3D print cell can produce a different job to help enable mass customization projects. Additional cells can be added at any time to the scalable platform to increase production capacity as demand requires. Automatic queue management, load balancing and architecture redundancy further lead to accelerated throughput as jobs are automatically routed to available print cells. If a single print cell fails, the job will be automatically rerouted to the next available cell.

Target applications include education rapid prototyping labs and environments that can benefit from zero tooling production and from a zero inventory supply chain.

“The Stratasys Continuous Build 3D Demonstrator is an important milestone in the company’s long term vision to make additive manufacturing a viable solution for volume production environments,” says Scott Crump, Stratasys co-founder and CIO. “It combines our FDM print quality, GrabCAD control and monitoring, and a new multi-cell, scalable architecture to create a breakthrough manufacturing platform.”

A variety of Stratasys customers, including designers and manufacturers, have begun using the Continuous Build 3D Demonstrator to enhance their offerings and explore new business opportunities. These include:

• Savannah College of Art and Design (SCAD), a preeminent art and design university, ensures all students have 24/7 access to state of the art 3D printing services. Installing a Stratasys Continuous Build 3D Demonstrator in the university’s Design Lab expands student learning opportunities in 3D printing, and the enhanced technological capacities benefit professors and students focused on advanced design projects and skills.
• In’Tech Industries, Inc., a premiere supplier of rapid prototyping/additive manufacturing, engineering services, tooling services and injection molding, wanted to expand its 3D printing offerings to create a bridge-to-production solution for their OEM customers. The automated workflow of the Stratasys Continuous Build 3D Demonstrator enabled In’Tech to offer same-day or next-day delivery of quantities of identical or mixed parts that would eventually be injection molded, helping the company dramatically improve customer service without adding additional staff.
• FATHOM, an advanced manufacturer with an expertise in additive technologies, is leveraging the Continuous Build 3D Demonstrator to push the limits of additive manufacturing. Many of its customers have adopted digital fabrication beyond prototyping as a means of production and are using proven additive technologies like FDM for high-value, end-use applications. Having a six-cell configuration in-house at FATHOM increases throughput significantly and enables a greater volume of FDM parts within a shorter lead-time. With the Continuous Build 3D Demonstrator, there is an opportunity to use FDM more effectively for not just a hundred just-in-time parts, but for 1,000+ parts on-demand.

Researchers at the University of Utah have developed a computer-driven automated drill, similar to those used to machine automotive parts, that could play a pivotal role in future surgical procedures. The drill produces fast, clean, and safe cuts, reducing the time a wound is open and the patient is anesthetized – one type of complex cranial surgery can be 50x faster than standard procedures, decreasing from 2 hours to 2-1/2 minutes –  reducing the incidence of infection, human error, and surgical cost.

To perform complex surgeries, especially cranial surgeries, surgeons typically use hand drills to make intricate openings, adding hours to a procedure.

“It was like doing archaeology,” says William Couldwell, a neurosurgeon at University of Utah Health. “We had to slowly take away the bone to avoid sensitive structures.”

He saw a need for a device that could alleviate this burden and make the process more efficient. “We knew the technology was already available in the machine world, but no one ever applied it to medical applications,” says Couldwell, who led an interdisciplinary team at the U to bring the drill into reality.

“My expertise is dealing with the removal of metal quickly, so a neurosurgical drill was a new concept for me,” explains A. K. Balaji, associate professor in mechanical engineering at the U. “I was interested in developing a low-cost drill that could do a lot of the grunt work to reduce surgeon fatigue.”

The team developed the drill from scratch to meet the needs of the neurosurgical unit, as well as developed software that sets a safe cutting path.

First, the patient is imaged using a CT scan to gather bone data and identify the exact location of sensitive structures, such as nerves and major veins and arteries that must be avoided. Surgeons use this information to program the cutting path of the drill.

“The software lets the surgeon choose the optimum path from point A to point B, like Google Maps,” Balaji says. In addition, the surgeon can program safety barriers along the cutting path within 1mm of sensitive structures. “Think of the barriers like a construction zone. You slow down to navigate it safety,” Balaji says.

The drill does the heavy lifting by removing most of the bone, similar to a mill, accurately and rapidly. “It’s like Monster Garage, except instead of machining a part, we are machining the skull,” Couldwell says. Couldwell applied the new drill to the translabyrinthine opening, a particularly complex jigsaw-like shape that circumnavigates the ear.

“The access is through the temporal bone which is a hard bone with strange angles,” Balaji says.

According to Couldwell, this particular cut requires a lot of experience and skill to perform it safely. “We thought this procedure would be a perfect proof of principle to show the accuracy of this technology,” he said.

The translabyrinthine surgery is performed thousands of times a year to expose slow-growing, benign tumors that form around the auditory nerves. This cut is not only difficult, the cutting path also must avoid several sensitive features, including facial nerves and the venous sinus, a large vein that drains blood from the brain. Risks of this surgery include loss of facial movement.

The device also has an automatic emergency shut-off switch. During surgery, the facial nerve is monitored for any signs of irritation.

“If the drill gets too close to the facial nerve and irritation is monitored, the drill automatically turns off,” Couldwell notes.

The new drill could reduce the duration of this complex procedure from two hours for hand-drilling by an experienced surgeon to two and a half minutes. The shorter surgery is expected to lower the chance of infection and improve post-operative recovery. It also has potential to substantially reduce the cost of surgery, because it shaves hours from operating room time.

The research team has demonstrated the safety and speed of the drill by performing this complex cut, but Couldwell stresses that it can be applied to many other surgical procedures.

“This drill can be used for a variety of surgeries, like machining the perfect receptacle opening in the bone for a hip implant,” Couldwell says.

The varied application of the drill emphasizes another factor that drew Balaji to the project.

“I was motivated by the fact that this technology could democratize health care by leveling the playing field so more people can receive quality care,” Balaji says.

Couldwell and his team are examining opportunities to commercialize the drill to ensure that it is more widely available for other surgical procedures.

Couldwell collaborated with colleagues from University of Utah Departments of Neurosurgery and Mechanical Engineering.

The research was funded by a Technology Initiative Grant through the University of Utah.
