What are the characteristics of grinding wheels and how to choose them A grinding wheel is a precision tool used in various industries for grinding, cutting, and polishing purposes. It consists of abrasive particles bonded together by a matrix material, forming a solid and durable wheel. The characteristics of grinding wheels play a crucial role […]
SLM (Selective Laser Melting) and EBM (Electron Beam Melting) are powder bed-fusion 3D printing technologies. A high-energy beam is used to fuse metal powder layer by layer to ultimately print a solid component. SLM has better accuracy and resolution than EBM. EBM, on the other hand, can print faster when compared to single-beam SLM machines. […]
Sintering entails heating and compacting a powdered material to create a solid mass with desirable properties. There are 13 different sintering methods, each with special benefits and uses. This includes pressure-assisted sintering, which improves densification, conventional sintering, a widely used technique, and the cutting-edge spark plasma sintering (SPS) technique, which is renowned for its quick […]
Elongation is the measurable tendency of a material to stretch when under strain. Engineers use a standardized testing procedure and a dumbbell-shaped test sample to evaluate a given material’s characteristic elongation behavior. The sample’s elongation is expressed as a percentage — its increase in length is divided by the original length and multiplied by 100 […]
Knowing the various properties of a material is critical to designing a part that can satisfy a particular function. An important property to be considered is the hardness (durometer) of a material. Durometer is a standardized method to measure a material’s hardness or resistance to localized deformation due to indentation or abrasion. It is often […]
Fused Deposition Modeling (FDM) is a 3D printing technology that builds parts by extruding a melted plastic filament onto the build plate one layer at a time. Digital Light Processing (DLP), on the other hand, creates parts by polymerizing a liquid photopolymer resin by projecting a single UV light image of the part cross-section onto […]
The critical advantages of FDM over FFF are: the resolution of the build (better-looking and more accurate models), and the reduced risk of distortion and porosity that results from a haphazard temperature environment. FDM vs. FFF: Technology Comparison FDM machines are well built, rugged, and capable and require little maintenance. FFF machines, on the other […]
3D printing is growing in both public recognition and overall added value, beyond prototyping and simple design. It is a revolutionary technology on the cusp of full-scale manufacturing capacity. While in recent years the consumer knowledge of 3D printing may have been limited to fashionable uses, like school science projects or as a tinkering toy […]
What Are ESD Materials? Electrostatic dissipative materials, or ESD materials, are designed to control and mitigate the buildup and discharge of static electricity. ESD materials for 3D printing are formulated with additives that impart electrical properties suitable for dissipating static charges. Additives such as carbon nanotubes or black carbon powders are typically incorporated into the […]
