In-process laser heating technique delivers a cost-efficient way to improve mechanical and geometrical properties to nearly isotropic and extremely smooth, respectively. The technique involves the incorperation of a solid-state laser into a commercial off-the-shelf 3D printer, mechanical system to allow controllable laser allumination on desired surfaces, and a gcode postprocesser to proper control of the mechanical system. This process uses laser for local heating, to enhance mass transfer between boundaries or to enhance surface reflow to smooth surface irregularity, to improve mechanical and geometrical properties. Only less than 3 W of laser power (CO2 laser) was used for high temperature material like PEEK and Ultem; less than 1 W (808nm laser) was found to be sufficient for achieving optimal properties for PLA. This technique has the potential for after-market integration into most commercial FFF 3D printers to achieved nearly isotropic and smooth 3D printed objects with various thermoplastic polymers.
There is a serious lack of local news in Arizona, the American Southwest, and the United States at-large. Arizonans are craving quality, factual, no-holds-barred journalism that is easy-to-read, and upfront. Quality, local news that covers the ins and outs of politics, culture, and community has an opportunity to not only enhance civic life, promote community healing, and expand knowledge made available to the general public (thus serving the communities it calls home), but to also generate revenue. Further, independent and center-right leaning voters in the state of Arizona — be reminded that independents make up the second largest voting bloc among Arizonans — are often crowded out in a media environment that consists of far-left nonprofit-funded news sites like the Arizona Mirror, formerly reputable papers that have bled readership as they veer further left like the Arizona Republic, and far-right online blogs that reach a very limited audience. The Western Tribune is an Arizona-based journalistic publication. This institution is dedicated to providing high-quality, well-sourced news and commentary on statewide, regional, national, and international current affairs through the lens of good government and free enterprise — as well as Southwestern values. We are a free institution that believes in free institutions. We cover stories that go uncovered because of the corporate media’s blind spots (and they’ve got many — they’re a result of news deserts and out-of-touch coastal attitudes) with the stable support of a robust institution dedicated to Truth-seeking behind them. Our storytellers are not just good writers. We seek to recruit and form critical thinkers with skills that span trades, disciplines, and educational backgrounds. We are building an institution committed to excellence.
