Infringement Ruling Against Envisiontec


3D Systems Announces Infringement Ruling Against Envisiontec

ROCK HILL, South Carolina – March 24, 2011 – 3D Systems Corporation (NASDAQ: TDSC) announced today that the United States District Court for the Eastern District of Michigan, Southern Division, has entered a judgment of patent infringement in its favor against Envisiontec, Inc., Envisiontec GmbH and SIBCO, Inc. (collectively, “Envisiontec”) in a case brought by the company.

The Court ruled that Envisiontec’s Perfactory® systems infringe a claim of the company’s U.S. Patent Number 5,630,981 and that Envisiontec’s Vanquish systems (currently sold under the PerfactoryXede® and PerfactoryXtreme® names) infringe a claim of each of the company’s U.S. Patent Numbers 5,630,981 and 5,651,934. Both of these patents relate to the company’s stereolithography technology.

“We are very pleased with this decision,” said Abe Reichental, 3D Systems’ President and Chief Executive Officer. “The District Court’s ruling confirms our long-held belief that Envisiontec has been violating 3D Systems’ intellectual property rights.”

3D Systems has commercialized the patents found to be infringed by Envisiontec, as well as other patented inventions, in its ViperTM and iPro™ SLA® production printers, among others.

Design Tip: Colorant and Color Matching


What Color is Your Prototype?

Injection molded parts, for all their many shapes and sizes, all start out pretty much the same—as small plastic pellets. The base colors of those pellets vary somewhat depending on the resin, but they all fall somewhere on a monochromatic scale from clear through various shades of natural to black (see Figure 1). Turning those dull little pellets into the rainbow of colors that comes out of molding presses requires the addition of colorant, which can be a fairly simple or fairly involved process. The complexity depends on how picky you are about your color.

Figure 1: Base color resins in their original pellet form. Left to right: acrylic (clear), ABS (natural), and glass-fiber nylon (natural).

If all you want, for example, is “red,” Protomold can add a stocked colorant to your base resin at no charge (see Figure 2). In fact, you can have your choice of Cherry Red, Flame Red, or Transparent Red, among others, though the exact color you end up with may depend somewhat on the shade of the base resin. If you want to see all the choices we offer, go to Protomold stocked colorants. Of course, how closely the final color resembles the color you see on your screen may depend on the screen itself, but it will certainly be red. If, on the other hand, you want a very specific color, say the blue of your corporate logo or the color-matched cap of a spray-paint can, the process becomes more complicated.

Figure 2: Adding Protomold stocked cherry red colorant to natural ABS created this plaque sample.

There are basically two ways to get colored injection molded parts. The simplest is to mix dye pellets into a batch of base resin pellets (see Figure 3). As the pellets are heated and compressed for injection into the mold, the base resin and dye pellets melt and mix together before being injected into the mold.

Figure 3: Typically colorant is mixed into base resin at 3% concentration to create colored parts. This photo shows a 3% colorant mix.

The other way is to order pre-compounded pellets in the exact color you want; for example, a standard PMS color or match to a sample swatch (see Figure 4).

Figure 4: Pre-compounded blue PC is supplied by a customer to Protomold for exact color parts.

There are several things you should keep in mind if you choose to have Protomold add the colorant.
1. As stated above, Protomold does not match specific colors.
2. The effect of base resin shade on final color is greater on light colors. In a pre-compounded color, this can be adjusted for in the compounding process, but may be noticeable when you use Protomold’s stock colors.
3. Because dye pellets are mixed with base resin pellets in a “salt and pepper” mix, there is a chance of "swirling” in the resulting parts (see Figure 5). The degree of swirling depends on a number of factors. “Hot” colorants—red, orange, yellow—tend to exhibit a higher swirling risk than cool colors like blue and green. Also, large parts, because they use more of the contents of the chamber in which resin pellets are melted and mixed, are less likely to show swirling than small parts.

Figure 5: Sample of swirling effect from a nylon material with yellow colorant. Choosing a pre-compounded resin would have helped the customer avoid this issue.

4. Unless you use pre-compounded colored resins, there is a risk of inconsistency from lot to lot and from part to part. This is one of the reasons that we recommend our standard ratio of three percent (3%) colorant (see Figure 6).

Figure 6: Colorant mixed with resin at 1, 2, and 3 percent ratios. With fewer dye pellets in the salt-and-pepper mix, the chance of uneven distribution goes up.

5. Certain base resins “don’t play well with others” when it comes to colorants. For these—high-temperature nylon and polycarbonate, for example—Protomold stocks a limited variety of resin-specific colorants. These allow you to achieve color but further limit your choice of hue.
6. Finally, certain resin characteristics—UV protection, flame retardant, and medical or food compatibility—can be affected by the choice of colorant. Protomold does not stock colorants specifically made to maintain these characteristics.

All of these problems have a solution: the use of pre-compounded resins purchased from specialized vendors. Pre-compounding consists of mixing colorant with base resin, melting and extruding the resin, re-pelletizing the resulting mix, and then repeating the process until a thorough mix is achieved. If necessary, the mix can be adjusted during the process to match the customer’s exact specifications. Vendors like RTP Plastics, PolyOne, Accek Color, Chase Plastic, and Compounding Solutions can match virtually any color in a wide variety of resins, and can preserve critical resin characteristics in the process (see full contact list below). Because the color is evenly distributed among the pellets, there are no issues of swirling or part-to-part inconsistency. Protomold can use these pre-compounded resins to produce parts, delivering all the benefits of rapid injection molding along with the exact color and characteristics you need.

catia to solidworks

A few weeks back I mentioned how I was confused as to why a CATIA translator in SolidWorks did not make the Top Ten list at SolidWorks WORLD this year. That one sentence began a firestorm of tweets about whether the translator was really a high priority among SolidWorks users.

First and foremost I need to mention that I live in West Michigan which is heavily entrenched in the auto industry. With that being said, almost everywhere I go and everyone I talk to in the Midwest have mentioned the NEED for the ability of SolidWorks to handle CATIA files natively. After all, both CAD programs are owned by parent company Dassault Systems.

One of the first comments made on Twitter stated the my feedback and the user base I usually talk to might be skewed compared to the entire SolidWorks user base and I totally agree with the comment. This may be the exact reason why it does not make it to the Top Ten list.

Still it leads to me think, what is the holdup of getting this translator incorporated into SolidWorks? There are many tools inside SolidWorks that are industry specific, things like Mold tools. So why should someone that has to constantly deal with CATIA files be forced to find workarounds in order to get their work done.

I personally know of a company that has a large number of SolidWorks licenses, however they also have a license of Autodesk Inventor for the sole reason of translating data. I am guessing that this is probably not how Dassault Systemes wants there customers working.

So what is the holdup? Is it pride? Is it the possibility of making more money by releasing an additional add in down the road that customers are going to have to buy? I don’t know the reasoning for it not being in the software already but I have to think that one of these is the deep rooted holdup. When or if it does come I sure hope that it does not come at an additional cost if you have the Professional or Premium SolidWorks packages.

This post is not meant to pick on Dassault Systemes, SolidWorks, a development team, or a specific development person but is more to ask the question of why are we still waiting. SolidWorks 2011 offers a wide range of translators for other popular CAD programs like Pro-E, Unigraphics, Inventor, Solid Edge, etc. but not CATIA yet.

Do you see the need? Why do you think we are still waiting?
