UMaine 3D Printing Process for Wind Turbine Blade Molds
UMaine 3D Printing Process for Wind Turbine Blade Molds
UMaine researchers have developed a 3D printing process for wind turbine blades
Developing the molds and tools used to manufacture large scale wind turbine molds is expensive and time consuming, sometimes costing millions of dollars and taking over a year to develop. Researchers at the University of Maine Advanced Structures and Composites Center are hoping to change that. They have developed a process for 3D printing segmented wind blade molds for large wind turbines using recyclable bio-based materials that are reinforced with wood. At the same time they are also working on combining the molds with a new process for robotic deposition of continuous reinforcing fibers in the blades. The UMaine Composites Center has the world’s largest polymer 3D printer, provided by Ingersoll Machine Tools, as well as a cellulosic-thermoplastic feedstock compounder from Techmer PM.
UMaine researchers have received a number of grants, including a $2.8 million grant from the U.S. Department of Energy Office of Energy Efficiency and Renewable Energy towards the 3D printing process and a $4 million grant from the Oak Ridge National Laboratory towards the robotic deposition of continuous reinforcing fibers. Companies like Siemens Gamesa and TPI Composites are also partnering on the project in hopes of using the new 3D printing process for their products.

Baker Hughes announces new composite flexible pipe solution for onshore energy and industrial applications
Houston, Texas based Baker Hughes recently announced a next generation of composite flexible pipe for the onshore oil and gas sector as well as other energy and industrial applications requiring cost-effective, corrosion resistant piping. The reinforced thermoplastic pipe (RTP) is spoolable and lightweight, making it easier and more cost-efficient to transport and install versus steel pipe. Customers who use the new pipe can see installed costs drop by more than 20% compared to steel pipe. The RTP piping also reduces environmental impacts and requires fewer onsite support facilities.
The new RTP pipe is designed for fluid pressures up to 2,250 PSI and temperatures up to 180°F. It is the only non-metallic RTP pipe on the market available in diameters up to 8 inches. Customers can also choose the type of liner best suited for their application: nylon, high density polyethylene (HDPE), and polyphenylene sulfide (PPS).

Procter & Gamble Partners with Rhinostics for New Injection Molded PP COVID-19 Nasal Swab
Procter & Gamble Partners with Rhinostics for New Injection Molded PP COVID-19 Nasal Swab
Procter & Gamble partnered with Rhinostics to develop a new injection-molded PP COVID-19 nasal test swab
Procter & Gamble (P&G) has partnered with Rhinostics Inc. to develop a new polypropylene (PP) nasal swab for COVID-19 testing. The new swab provides up to 30 times greater sample concentration versus other swabs used in the front of the nose. The new swab provides additional supplies for COVID-19 testing, reducing supply shortages, and provides a more comfortable testing experience. Fully injection molding nasal swab reduces handling and lab processing time leading to an increase in manufacturing capacity.
P&G subsidiary iMFLUX created the swab and is licensing it to Rhinostics for manufacturing and disbursement. Rhinostics plans to seek Emergency Use Authorization for home collection rPT-PCR testing for COVID-19 testing and could be expanded in the future for other testing needs, like influenza, as well. You can see an image of the swab and read more about it here.

PPI Releases New Technical Report on PEX Pipe and Tubing Freeze-Break Resistance
PPI Releases New Technical Report on PEX Pipe and Tubing Freeze-Break Resistance
PPI has released a new technical report on PEX pipe and tubing freeze-break resistance and benefits
The Plastics Pipe Institute, Inc. (PPI) has released a new technical report titled “TR-52 Resistance of PEX Pipe and Tubing to Breakage When Frozen (Freeze-Break Resistance)”. The report focuses on crosslinked polyethylene (PEX) pipe and tubing and how it performs when fluid inside freezes. It also details installation and protection measures that can be done to help prevent the fluid inside from freezing in the first place.
According to Lance MacNevin, P. Eng., director of engineering for PPI's Building & Construction Division, “The inherent flexibility of crosslinked polyethylene (PEX) results in excellent freeze-break resistance. This means that if water or fluid-filled PEX pipe or tubing freezes, the elasticity of the material typically allows it to expand without cracking or splitting, and then to return to its original diameter upon thawing. However, there are installation variables that can cause PEX to fail in certain situations, which are described within this report, and the freezing of fluid within any type of pipe should be prevented for multiple practical reasons.” TR-52 also includes recommendations for how to protect pipes in specific applications.
