    Titanium is the perfect metal to make replacement human body parts

    Titanium material is expensive and can be problematic when it comes to traditional processing technologies. For example, its high melting point (1,670℃, much higher than steel alloys) is a challenge.

    The relatively low-cost precision of 3D printing is therefore a game-changer f…[Citește mai mult]

    PHOTOLUMINESCENT POWDER INTRODUCTION
    Photoluminescent powder, also known as pigment, is a non-toxic, non-radioactive new environmentally friendly alkaline earth aluminate pigment. Most of the visible or UV light will charge the pigment particles (excitation). The photo luminescent pigment then releases energy for 10 to 24 hours in the form of…[Citește mai mult]

    If steel and titanium are both equal in strength, then aluminum is half the strength. When you get into the 7000 series of aluminum they get to about two thirds the strength of titanium. The problem is that the ductility of aluminum is less than steel. This is what comes into play when designing parts, especially the axles and some bolts, like…[Citește mai mult]

    LED stands for light emitting diode. LED lighting products produce light up to 90% more efficiently than incandescent light bulbs. How do they work? An electrical current passes through a microchip, which illuminates the tiny light sources we call LEDs and the result is visible light. To prevent performance issues, the heat LEDs produce is…[Citește mai mult]

    IPL treatment of PWS
    IPL devices are broadband filtered xenon flashlamps that work based on the principles of selective photothermolysis. The emission spectrum of 515–1200 nm is adjusted with the use of a series of cut-off filters, and the pulse duration ranges from approximately 0.5 to 100 msec, depending on the technology. The first commercial s…[Citește mai mult]
