Next up in our series on 3D-printing technology for rapid prototyping is Selective Laser Sintering (SLS). SLS is an additive manufacturing (3D printing) technology that uses a high-power laser to fuse small particles of plastic powder together, printing parts in 3D one layer at a time. For each layer, the laser traces the cross section of a part onto the surface of a bed filled with powdered […] READ MORE

This blog series explores 3D printing options that are available today. In our 3D-printing series this month, we look at photopolymer jetting or “PolyJet” as it is typically known. PolyJet is an additive manufacturing process like FDM and SLA. PolyJet printers use liquid photopolymer urethane materials that are sprayed on layer by layer and instantly […] READ MORE

Pongratz Engineering is exhibiting at the 2014 LifeScience Alley Conference on November 19, 2014. There will be presentations by cutting-edge researchers and industries. In addition, there will be opportunities for high-level networking with your fellow life science and healthcare industry peers (like us!). Attend this year’s Conference at the Minneapolis Convention Center. READ MORE

The latest innovation in dental patient comfort is now on the market. The Restful Jaw external jaw support device makes visiting the dentist far less painful, especially for patients who experience jaw pain and soreness. Pongratz Engineering was thrilled to help the company move their prototype into production, navigating the quoting, documentation, project management, and vendor […] READ MORE

  Brooklyn Bay Bicycles hired Pongratz Engineering to help make their bike spinner design a reality. The result? NuGeneration spinners that can be made in different colors and operate in three distinct modes. After proving it out, Pongratz Engineering also helped make them a starter website/email and a Kickstarter campaign, complete with videos. Check out […] READ MORE

This blog series explores 3D printing options that are available today. One of the more exotic and high-performance technologies available is Direct Metal Laser Sintering (DMLS). DMLS is a relatively new rapid prototyping process that uses a focused laser beam to fuse metal powder together layer by layer, creating a 3D model of the part. […] READ MORE

What is Fused Deposition Modeling (FDM)? The first technique we’ll examine is Fused Deposition Modeling (FDM), one of the most popular rapid prototyping technologies at the moment. It has been referred to as the “workhorse” of the 3D printing world. FDM is an additive manufacturing technology, meaning it builds up a part layer by layer. […] READ MORE

3D printing … Yes, it is likely you have heard the term by now. The term is starting to be used like “Xerox” or “Google”. In the engineering and product-design world, 3D printing is also known as rapid prototyping. Engineers use it to validate designs, make work-holding fixtures, and even for low-volume manufacturing. There are […] READ MORE

    This is the first in a series about selecting product design and engineering services. Who needs product design services?  Start-up companies or companies ready to refresh their product lines: They need a solid product design that will quickly go to manufacturing, and they don’t have the time or skills to design it themselves. […] READ MORE

Developed by Pongratz Engineering, LLC. and Bernie White (Desert Eagle), this unique front and rear shotgun sight system outfits a traditional Remington 870 (and similar shaped receiver shotguns) with a Picatinny rail and fully adjustable Ghost Ring sights. This system offers a longer rail for more scope mounting options, green/red fiber optics and aggressive tactical […] READ MORE

Sorry machine shops. More and more our customers are discovering that 3D printed parts can be used for fixturing. Typically these fixtures are used for assembly, testing, and even drilling/cutting. Where are 3D printed fixtures used? Applications include: ASSEMBLY FIXTURES hold cases in alignment while screws are put in place. 3D printing makes sense in […] READ MORE
