List -

Don't get me wrong - I am not out to "bash" someone for their work, But as
Doug points out, the cost limit was $100,000. The viper is about a $200,000
unit. Why include it? It will skew the stats, the same as less-than-full
distinction between subtractive and additive methods will.

  Have you read the whole report or just the Executive summary?

  Did you notice on the website that one of the criterium wasa cost of
  under $100,000?

  The Eden has just been announced, and is essentially a more accurate
  Quadra Tempo. As for the _E_nvision, there are not enough units in the
  field to be able to include them in any studies.

  Todd Grimm has been around the RP industry longer than most people have
  known what defines RP.

    Dear List,

    Went thru the report !

    Some questions :

    1. Is this site marketing site for selling reports ?

    2. This report is definitly not made by any RP Veteran but some novice

    3. Everybody knows that Viper is serious high end RP system not 3D
Printer. Why include it in the comparisons ? Viper accuracy same as
Dimension printer ? Ha Ha , who are they fooling ? Ask Fine Line Prototyping
or experts from 3D Systems, please wake up, or these fools will confuse the
market ! I doubt the credibility of of the publishers

    Why Invison, Eden is missing my friend ?

      Edgewood, Ky., October 27 -- T. A. Grimm & Associates, Inc. today
      announced the release of a new rapid prototyping benchmark study that
      examines 3D printers. This extensive study reports the performance of
      seven rapid prototyping systems in the areas of time, cost and

      3D printers are affordable and easy to use rapid prototyping systems
      personal, office or departmental use. The benchmark study finds that
      five of the seven systems qualify as 3D printers, as illustrated by
      new Rapid Prototyping Index. A ranking methodology that incorporates
      performance measures, the index rates the systems in four applications
      areas: concept models, form and fit prototypes, functional prototypes
      and patterns.

      Todd Grimm, president of T. A. Grimm & Associates and a veteran of the
      rapid prototyping industry, conducted the five month project to assist
      companies in their evaluation and selection of 3D printers. Using
      independent organizations for all prototype construction and quality
      measurement, the benchmark offers an unbiased comparison of the seven
      rapid prototyping systems.

      "I produced this benchmark study specifically for design engineers who
      are trying to select the rapid prototyping system right for them,"
      Grimm. "Beyond vendor supplied data, there has been little information
      to help companies discover the true performance capabilities of rapid
      prototyping devices. Without real-world, user- supplied data, this can
      lead to poor decisions when selecting a system."

      The 55-page benchmark, which contains 34 charts, 5 tables and 36
      reports results for three prototypes that vary in size, volume and
      complexity. The benchmark study discovered that there is a large
      variance in prototype costs, ranging from $6! 0.53 to $267.85. The
      measures include system and accessories costs, annual costs, labor and

      The report is available for purchase at T. A. Grimm also offers a free
      executive summary of the benchmark results at the same Web address.
