“Working on the principle of centring the workpiece on its outside diameter without the application of pressure, then clamping from the inside diameter, InoTop prevents unwanted polygon formations in the clamping process and results in the efficient production of high-quality parts.”
At RAPID + TCT, Impossible Objects unveiled its new generation 3D printer, the CBAM-2, capable of faster printing on a larger area with high-strength composites. The new machine has bulk ink cartridges and automatic powder filling, giving it greater autonomy between refills. “It’s a very significant improvement. It gets us closer to our goal of ‘set it and forget it’” says Bob Swartz.
The team performed numerical simulations to study the effects of various parameters — such as the size of cavity or flow rates — on the vortex magnitude and shear stress, as well on particles leaving the cavity to re-enter the channel. In this way, the researchers mimicked the response of blood cells under disturbed flow situations, similar to that found at junctions and curvatures of coronary and carotid arteries.
As a result, “for companies in the digital manufacturing space, there’s a silver lining to the dark cloud of the trade war. Suddenly the risk-benefit calculation of investment in digitization starts to look more attractive, purely as an economic proposition. For one, sourcing parts out of China is becoming riskier and potentially more expensive.”

August gold futures (GCQ19) have gained 3.2 percent over the past five days to trade at $1,331.20 at 3.15 pm EDT Monday, a level they last touched more than three months ago. The contract climbed $20.20 per ounce on Monday’s session alone, one of its biggest one-day gains so far in the year.

The results are manifest in a wide range of CNC milling issues often attributed to other causes: vibration and chatter, poor tolerances, non-repeatability, poor finishes, shortened tool life, excessive spindle wear, run-out, and shallow depths of cuts.
The property was used for industrial operations until 1987, and was contaminated with chloroform, heavy metals, polycyclic aromatic hydrocarbons and PCBs, according to a release announcing the grant.

Figure 1 This is a completed CAD model for a washer punching tool. The same software that is used to design machined parts can be used for 3D-printed components.
There is tremendous pressure on machined parts suppliers to deliver more for less, and always on time. Physics-based feed rate optimization enables shops to spend minimal time preparing highly optimized toolpaths that run smoother and deliver big savings at the machine. Feed rate optimization software determines the maximum reliable feed rate for cutting conditions encountered (in simulation) and calculates feed rates to remove material under ideal conditions. In addition to reducing machining times, machined surface quality and tool life are also improved. Using feed rate optimization software that is independent of your CAM system(s) provides the ability to optimize new and existing or legacy NC programs, so they all cut as efficiently as if they were created by a machining expert.
“We are truly living in an on-demand consumer economy and that’s no different for manufacturing,” said Vicki Holt, President and CEO. “Our customers are hungry for manufacturing partners that can see their products through ever-shrinking life cycles, and Protolabs is uniquely positioned to serve our customers’ needs from early prototyping to on-demand production.”
EVA ZUREK: Right there was– actually, so there’s the BCS theory of superconductivity that explains a certain class of superconductors. It doesn’t explain why the copper oxides are superconducting. We still don’t really know that.
