What's the Right 3D Printing Technology - FDM or Polyjet?

Fused deposition modeling (FDM®) and PolyJet® are two of the most advanced and effective additive manufacturing (AM) or 3D printing technologies available. They span the range from budget-friendly, desktop modeling devices to large-format, factory-floor equipment that draw from the capital expenditure budget, and can produce a range of output from precise, finely detailed models to durable production goods. While there is crossover in applications and advantages, these two technology platforms remain distinct and bring different benefits. Understanding the differences is the baseline for selecting the right technology for your application, demands and constraints.

Using PXI to Build a High-Performance MEMS Microphone Testing System

The demand for increasing microphone signal quality from handheld mobile devices has led to the development of microphone signal processing technologies such as: HD audio, noise cancellation, active noise cancellation, beam forming, directional reception, stereo sound field reconstruction, and speech recognition. As well, devices incorporating multiple microphones are becoming more and more popular. Several newly released smart phones now integrate multiple MEMS (Micro Electrical-Mechanical System) microphones for improved background noise cancellation. All flagship smart phone models in introduced in 2015 featured three or more MEMS microphones to support HD audio, ambient noise cancellation, noise filtering, directional reception and speech recognition. Popularity of MEMS microphones is expected to grow.

Forging as a Viable Alternative to 3D Printing of Non-Ferrous Metal Parts

3D printing is an additive manufacturing (AM) technology used to build objects layer-by-layer directly from digital data. It has surged in popularity in recent years because it enables fast and flexible product design and prototyping, and can be used to produce small numbers of parts cost-effectively, and create complex parts that are difficult or impossible to make otherwise.
