Dive into our latest blog to uncover the real #innovation: the BLUE LASERS incorporated in our just launched #metal #industrial #3dprinter, the #MeltioM600! 💥 In wire-#DED processes, high-power #lasers are used to melt and deposit wire filler #material. The use of powerful #blue lasers offers lots of advantages! 👉 Better #metal #absorption: Blue lasers make metals absorb better. With their wavelength reduced to 450 nm, more laser #energy is used to heat and melt the #metal, making deposition faster and more #efficient. 👉 Faster, greener #printing: Picture this, printing metal parts at lightning speed while cutting down on energy consumption. With faster deposition using the same laser power, we're not just printing, we're printing smarter, greener, and with a reduced environmental impact.  👉 #Versatility unleashed: Say goodbye to limitations. Blue lasers unlock a wider range of printable materials by enhancing light absorption.

If for many #users, #lasers are directly associated with more #speed, the key to achieving product #quality and increased #productivity in #manufacturing often comes down to the type of lasers the #3dprinter is equipped with. Interestingly, different #additivemanufacturing processes require different types of lasers. The article below aims to shed light on important laser parameters relevant to AM and highlights specific considerations for selecting the ideal lasers for one’s AM equipment.

📣📣Excited to share our latest research paper, recently published in Chemical Engineering Journal (CEJ). Although dielectric elastomer switches (DES) were first introduced in 2010, challenges such as poor reproducibility, slow response time, and short durability have remained. In this study, we successfully addressed these issues by utilizing inkjet printing with our custom-formulated carbon black ink to develop a high-performance DES. This fully soft DES achieved an impressive resistance change of approximately 3.8 orders of magnitude at 0.1 Hz. 🤔What is a dielectric elastomer switch (DES)? 👻DES is a piezoresistive sensor where dielectric elastomer actuator (DEA) electrodes and a piezoresistive pattern are fabricated side by side on a single monolithic dielectric elastomer film. When no high voltage is applied to the DEA, the conductive particles in the piezoresistive pattern remain disconnected, exhibiting high resistance (> 1E10 Ohm). When a high voltage is applied, the DEA actuates, compressing the adjacent piezoresistive pattern and forming conductive paths, thereby reducing the resistance (~ 1E6 Ohm). DES technology has been used to create logic gates, oscillators, motors, transistors, and multiplexers.

But how can you leverage HIP to achieve cost-neutral production while speeding up the process for high-volume AM parts? Techniques like multiple lasers in PBF-LB and optimizing melting speeds and powder layers are being used to crank up the deposition rate of PBF-processes. However, pushing the speed limits too much will eventually lead to detrimental build defects like pores, voids, lack of fusion (LoF), and micro cracks. By integrating HIP and High Pressure Heat Treatment (HPHT™) to your AM workflow, you can ramp up production speed without sacrificing quality. This results in higher output, fewer defects, and a lower cost per part, making HIP a cost-neutral investment—essentially giving you "HIP for free”.

Optimising #Additive #Manufacturing to Produce #PLA Sandwich Structures by Varying Cell Type and Infill: Effect on Flexural Properties by Gabriele Marabello, Mohamed Chairi and Guido Di Bella J. Compos. Sci. 2024, 8(9), 360; https://lnkd.in/dzG-pj_F Abstract The objective of this research is to optimize additive manufacturing processes, specifically Fused Filament Fabrication (FFF) techniques, to produce sandwich structures. Mono-material specimens made of polylactic acid (PLA) were produced, where both the skin and core were fabricated in a single print. To optimize the process, variations were made in both the base cell geometry of the core (Tri-Hexagon and Gyroid) and the core infill (5%, 25%, 50%, and 75%), evaluating their effects on static three-point bending behavior. Optical microscopy was employed to assess both the structure generated by additive manufacturing and the fracture modes. The findings reveal that increasing the infill, and thus the core density, enhances the mechanical properties of the structure, although the improvement is such that samples with 50% infill already demonstrate excellent performance. The difference between hexagonal and Gyroid structures is not significant. Based on microscopic analyses, it is believed that the evolution of 3D printers, from open to closed chamber designs, could significantly improve the deposition of the various layers.

I am thrilled to share our recent collaboration with BAM Germany Bundesanstalt für Materialforschung und -prüfung, published in the journal Materials & Design! I would like to thank all the coauthors for a great collaboration: Tatiana Mishurova, Laura Cordova, Mats Persson, Giovanni BRUNO, Eugene Olevsky, and Eduard Hryha. Characterizing the sintering process has been challenging due to the high porosity and fragility of green compacts. Our research addresses this gap by employing high-resolution synchrotron X-ray computed tomography (SXCT) on BJT 316L samples from ex-situ interrupted sintering tests. We identified periodic density fluctuations along the building direction, directly linked to the original printing layer thickness and its reduction during sintering. Utilizing a BJT-specific continuum sintering model, we replicated density evolution and captured the fluctuation decrease from green (1.66%) to sintered (0.56%) state. This research offers valuable insights for optimizing BJT printing and sintering parameters, ultimately leading to more robust and reliable BJT components. Our findings pave the way for further investigations into the influence of printing parameters, powder properties, and sintering strategies on density evolution.

#100daysampdesign I came across a fascinating YouTube video detailing a homemade semiconductor fabrication setup! The video offers a glimpse into the world of low-cost chip fabrication, listing tools and materials used for various processes. The presenter, Sam Zeloof, demonstrates remarkable resourcefulness, building most of the tools himself and spending around $35 for a key component – a quartz tube furnace. He also cleverly utilizes surplus materials from online retailers. Here's a breakdown of some key tools and materials featured in the video: Spin coater: A creative combination of a muffin fan and a 3D printed dish. Hot plate 3D rotator mixer Wafer pieces: Silicon dioxide layer, phosphoric acid solutions, dopant materials Furnaces: Two furnaces, one for oxidation and another for diffusion Nitrogen tank Tube furnace: A quartz tube furnace for fusion welding Chemicals: Hydrofluoric acid, ammonium hydroxide, hydrochloric acid, sulfuric acid, etc. (Safety reminder: Always handle these chemicals with extreme caution!) Mask: A vinyl cut mask to define active areas on the wafer Wafers: n-type and p-type wafers, the building blocks of integrated circuits Photoresist: A light-sensitive chemical used for patterning circuits on the wafer DLP projector: Used for a maskless photolithography process Vacuum chamber: For thermal evaporation, a process of depositing thin films Roughing pump and turbo molecular pump: These pumps create a near-vacuum environment essential for evaporation Microscopes: For inspecting wafers at various stages of fabrication Leak detector: To ensure the integrity of the vacuum chamber Thermal evaporator: For depositing thin metal films onto the wafer Kiloamp power supply: Likely used for powering the evaporation process It's important to note that this setup prioritizes affordability over industrial-grade precision. The video acknowledges that the yield (usable chips per wafer) might be lower compared to high-end fabs. However, this project serves as a remarkable example of what can be achieved with ingenuity and resourcefulness. Sam Zeloof Pipeloluwa Olayiwola
