    How to Use SOLIDWORKS for Gravity Casting

    April 19, 2021

    Castings are a very powerful form of engineered metal component, and examples abound around us. From rivets and buttons in blue jeans to flight-critical turbine blades and airframe nodes, castings serve us well, worldwide. Castings can be formed from any alloy family in a myriad of mold types. How those mold types are formed now embodies the most cost-effective applications of additive and subtractive manufacturing.

    Design engineering of excellent castings is difficult, and excellence in manufacturing engineering of the design to assure specified quality is critical. Software tools that encompass design engineering, durability analysis and manufacturing engineering are powerful, but disjointed, expensive and require specialized expertise. The SOLIDWORKS software suite can be used in a new and innovative way to make casting design and manufacturing engineering coherent, integrated and easier to accomplish exemplary results. This article will focus on how to develop the foundational castability geometry so that structural geometry can be overlaid in a castable result.

    3D Scanning Forensic Methods

    January 2, 2019

    Forensic teams have been documenting crime scenes with cameras for decades. They also use approximate measurement methods, such as a tape measure, that can only be performed at the crime scene. The 2D images that cameras generate, even with the highest quality, lack crucial data that only spatial relations between objects can create. These parameters can be of such critical value that they may determine whether the criminal justice system ends up prosecuting an innocent person and vindicating the offender. 3D scanners may be just what they need to change the outcome.

    3D Scanner Technology to Reverse Engineer a Custom Mouse Case

    October 12, 2018

    3D scanning is an increasingly popular technology and is mostly used for reverse engineering and quality assurance. Reverse engineering is commonly known as backward engineering because it's the process through which information is extracted from pre-existing objects to reproduce them based on the information gathered.

    Innovative Use of SOLIDWORKS for Better Casting Designs

    February 16, 2018

    Did you know there is a major untapped resource within SOLIDWORKS Flow Simulation? And it may be the answer to all your metal casting problems! Say goodbye to fits, restarts, re-tooling and launch delays with Thermal Flow.

    Make Your Own Solution: Tripod Attachment

    November 8, 2016

    Don't you hate when new technology doesn't fit your tripod from the 80's? Us too! That's why in this week's “Make Your Own Solution” blog, I decided to work through the problems I encounter using my old tripod and tackle new ways to attach a cell phone to the mount. This is the solution I came up with:

    Make Your Own Solution: Custom Car Logo

    September 23, 2016

    Join me, one of TriMech's Application Engineers, as I help a friend replace an old, chipped Chevy logo with a 3D printed replacement. I used SOLIDWORKS and the Stratasys uPrint 3D printer to make this logo in only a few hours.
