Hey Folks,
I need to purchase STL files of mermaids. Have a project, need the data. Anyone know where I can buy these?

  A few years back I performed a similar sounding study for Volvo Cars as part of our Rapid Manufacturing Consortium.
  A couple of key points to make with this kind of benchmark include:
  - the findings are often geometry/purpose specific
  - the findings are often out of date by the time they go to print.

  I have not read the report but would expect that Todd has covered the first point, previous work by him appeared to be well balanced and fair.
  The second point is very important to remember however it does not mean there is no value in the excercise, it's just that the reader should be aware of its limitations (ideally the author will make this clear).
  The second point is in fact a credit to system/material developers - paradoxically it is good news if the report is out of date quickly as it (usually) means significant improvements have been made.

  I look forward to watching a lively debate!

    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 individual.

    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 quality.

      3D printers are affordable and easy to use rapid prototyping systems for
      personal, office or departmental use. The benchmark study finds that
      five of the seven systems qualify as 3D printers, as illustrated by the
      new Rapid Prototyping Index. A ranking methodology that incorporates 13
      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," said
      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 images,
      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 $60.53 to $267.85. The expense
      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.
