Computer Simulation and Analysis

Overview

I provide innovative product design solutions for the consumer, industrial, medical, scientific, military, and transportation industries. Whether a one-off custom medical device or an electronics enclosure mass-produced in the millions, your project can be seen through any and all stages of design from an initial concept up to manufacturing. I create  designs optimized for function, cost, and aesthetics using a less-is-more philosophy that considers every detail. I am passionate about creating quality, beneficial, and successful products.

  • I have worked directly with Adam on 15-20 design projects over the past few years. On several occasions, I asked Adam to apply his creativity to the design process and think outside the box. As a result, Adam found clever solutions to some tricky design issues we have since adopted. We 3D-print most designs to validate fit and function and make necessary revisions. Adam is our "go to" mechanical engineer for most of our requirements and I value his friendly, collaborative engagement.

  • After a frustrating search for a CAD/design specialist to assist me with a new product idea, I found Adam Freund Design. I sent Adam a decription of my envisioned product, as well as photos of a crude clay model. In a few days he sent me renderings and a 3D model that were a near perfect capture of my idea. We collaborated closely to finalize the design, whereupon Adam provided me with production-ready CAD files that I used to get a 3D printed prototype and I can also use for manufacturing. Adam's active assistance, fast turn-around times and mastery of the requisite skills made the design process quick and efficient.

  • I came to Adam as a first-time product designer with a concept I needed designed in CAD and optimized for plastic injection molding. Adam was very professional and provided additional design options to improve the product. He was quick to provide the exact files and drawings the manufacturer required, and helped speed the process by communicating directly with my mold manufacturer. I now have successfully launched my first dog owner product!

  • Stop looking at any other designers and hire Adam right now, before he gets too busy. Seriously - do it right now. This guy is off-the-charts GREAT with communication, insight, and design capabilities. He is fast and fun to work with. I no longer need any other designers in my rolodex; Adam is my go-to from now on.

CAD

Computer-aided design has revolutionized the way products are designed, with its capabilities increasing each year. I utilize top-of-the-line software and techniques to produce the highest quality results in the most efficient manner, giving my clients the best possible value. I stay up to date with the most effective technologies and techniques to provide highly functional and competitive services.

My primary CAD tool is SolidWorks® Premium, run on a high-end workstation specifically built for this purpose. My experience with SolidWorks® includes four years of formal education and scholarly use during my mechanical engineering degree studies and full-time professional use since early 2011. I also utilize Adobe® Illustrator®, Autodesk® AutoCAD®, Autodesk® Fusion 360®, Autodesk® Remake®, DS Photoview 360™, and Meshlab™ software. See the Software and Equipment sections near the bottom of the page for more information.

My abilities include, but are not limited to organic shapes, machine parts, complex assemblies, 2D cutting files, files for 3D printing, file conversion, files for manufacturing, 2D to 3D conversion, computer simulations and analysis, parametric modeling, photorealistic rendering, 2D dimensioned drawings, bill of materials, and tolerancing. I am able to import and export essentially any 2D and 3D file type there is. 


Design For Manufacturing

 Laser Cutting

I create designs optimized for Injection Molding, Extrusion, CNC Milling, Routing, and Turning, EDM (Electrical Discharge Machining), Laser Cutting, Water Jetting, Swiss Screw, Milling, Lathe, 3D Printing, Punching, Casting, Stamping, Bending, Thermoforming, Laser Marking, Anodizing, Chemical Etching, Welding, Blow Molding, Dip Molding, Routing, and many other manual and automated processes. Considering how a product will be made is an integral part of my design process and not an afterthought. This prevents having a beautiful design that cannot be made and must be completely redone. It also allows production costs to be greatly reduced.


Reverse Engineering

Through the use of accurate measuring tools, 3D scanning and/or photographs, I can take an existing product and precisely replicate it as a 3D CAD model. Existing designs can then be modified to your specifications or can be used as a starting point for a new product. The resulting CAD model can then be used for manufacturing, 3D printing, photorealistic renderings, and more. I can also tell you how an existing product was manufactured and provide suggestions on how it can be improved. Whether you need to replicate a rare part for a vintage machine or make modifications to a competitor's product for mass production, I can provide the precise engineering detective skills needed to accurately replicate and modify an existing product. 


Prototyping and 3D Printing

3D-Printing-and-Prototyping

I can bring your product to life with my in-house prototyping capabilities. Physical prototypes and proof of concept models can be an invaluable tool during the design process and also serve to validate a design, allow for testing, and attract investors. They could also be the final product themselves for one-offs and low-volume production.

In addition to the vast array of high-quality 3D printing options I offer, I also take care of other basic prototyping needs with my ever-expanding list of capabilities, including thread-tapping, hole-drilling, cutting, routing, thermoplastic bending, soldering and basic electric circuit assembly, part bonding, surface finishing (sanding, tumbling, chemical vapor treatment), painting and assembly. I stock a large supply of off-the-shelf hardware such as screws, nuts, washers, electrical components, wire, pipe, spacers, magnets, rubber bumpers, adhesives and springs for quick prototype turnaround. I can also source whatever other components you may need.

For prototyping needs I can't take care of in-house, I frequently work with numerous local, domestic and international manufacturers and equipment-sharing partners with additional capabilities. Examples include CNCing, water jet cutting, laser cutting, milling, laser marking, anodizing, welding, injection molding, metal 3D printing, dip molding, punching, bending, and extruding.

3D Printer Info

  • Model: Ultimaker 2 Extended+
  • Huge Usable Build Volume: 223 x 223 x 305 mm (8.8 x 8.8 x 12.0 in)
  • Best Available Resolution: 0.02mm (20 Micron) minimum layer thickness
  • Many material and color options: PLA, ABS, flexible and rubber-like plastics, CPE, nylon, PET, metal-filled, carbon fiber-filled, transparent, glow-in-the-dark, high-temperature plastics, in any color imaginable

Available Materials:

  • PLA {Polylactic Acid): The most common printer material used today. Corn-based, bio-degradable, and unlike other commonly used materials, doesn't give off hazardous fumes while printing. This is the easiest material to print with, and is my go-to for most prints, unless there are reasons to do otherwise. Available in a wide range of colors.
  • ABS (Acrylonitrile Butadiene Styrene): Originally the most commonly used 3D printing material, ABS has now fallen out of favor to PLA. However, ABS still has its benefits, including improved strength and flexibility over PLA as well as the ability to be chemically smoothed. 
  • CPE: Similar properties to ABS, but without the harsh fumes.
  • Flexible PLA: Similar to PLA, but formulated in a way that gives it rubber-like characteristics.
  • Nylon: Extra tough and strong for mechanical parts.
  • Exotics: Examples include plastics with metal, wood, or even carbon fiber infills to give different aesthetic or functional properties.

Finishing: Due to the inherent nature of the 3D printing process, which builds up parts one layer at a time, the individual layer lines are typically visible to some degree. This is fine for most purposes, but if you would like, there are a variety of finishing options available (for an additional fee). It is possible to smooth over ABS using an acetone vapor bath. The resulting appearance is smooth and glossy, similar to an injection molded part, and has the added benefit of increasing part strength by better bonding the layers. It is also possible to mechanically tumble any material (think rock tumbler), as long as the part isn't too big or fragile, with a variety of abrasive materials to help smooth out a part. I can also fuse together extra large parts that must be printed in separate batches and paint, cut, drill, tap, and assemble parts.


Computer Simulation and Analysis

Static Force Linear Computer Simulation with SolidWorks Premium

I use SolidWorks Simulation Premium to perform:

  • Finite Element Analysis (FEA)
  • Static Force, Thermal, Frequency, Buckling, Drop Test, Fatigue, and Pressure Vessel Simulation
  • Linear, Nonlinear, and Linear Dynamic Analysis
  • Motion Analysis
  • Tolerance Stack-Up Analysis
  • Fluid Flow Simulation
  • See the stresses, strains, deflections, deformations, movement, temperature distributions, and failures in your product before spending a dime to build it.
  • Simulations and analysis can be performed on individual components or entire assemblies
  • Top-of-the-line, custom-built computer workstations and overnight scheduling of consecutive simulations allow me to provide fast and economical simulation results that don't skimp on accuracy or resolution.

Photorealistic Rendering

Accurately visualize your product without needing to first have a physical model built. Renderings can be used to aid in the design process, entice investors, and create marketing materials. They often can better showcase your product than professional photographs of the real thing, and can be used on your website or as a catalog image.

Photorealistic renderings can be produce once there is a 3D CAD model of your product. The visual properties (material, surface finish, color, etc.) of the different components of your product are individually fine-tuned. The lighting and environmental settings are carefully selected to show off your product. Renderings can be exported as high-resolution images in any image file-type (JPEG, PNG, BMP, etc.). I have the computer power to produce the most accurate and high-resolution images you will ever need. Batches of multiple renderings can be scheduled to run overnight, allowing for quick turnaround times and cost savings.


Feasibility Consulting

Can your envisioned product be manufactured? Is it's intended functionality even possible? The vast majority of new product ideas are never realized, often after a huge amount of time and money has been expended. I can provide the vital information you need to know before heavily investing in a new idea. I can estimate design costs, prototype costs, and manufacturing costs as well as tell you if your desired product is functionally possible. I can provide solutions you have not considered and help determine the best way to proceed. Identify risks and choose the most promising direction early on. This could easily be your biggest ROI.

Get a second opinion from someone who hears about 1,000 new product ideas every year and has seen what is successful and what flops. Even in just an hour, I can provide you with initial direction, potentially saving you thousands. I won't hold back ideas. If I see any flaws or major obstacles that will need to be overcome, I will be brutally honest with you.

Send me any relevant info pertaining to your product and we can schedule a time to talk. I will review your idea before our discussion, do any necessary research, look for challenges, and brainstorm ideas. We will then have a meeting where I can try to answer any questions you may have, give my opinion on the idea, suggest manufacturing methods, give cost estimates, etc. Pricing starts at $100 for a one-hour meeting (and prior review of your provided information).
