Significant price reduction on dense models

From today until the 22nd of next month there is a significant discount
selected models on the site. Sean’s Oloid is not $95 but $66. Basically models with a density higher than 10% that are larger than 20cm3 get
50% discount on the cm3 that exceed the first 20cm3. The discount is over the material price not the mark up of the designer so there will be differences between models. Why & how are we doing this? Have we gone nuts?

We strive to make Shapeways as accessible as we can. We want to
make it easier and more affordable all the time. Eventually it is our
goal to let you make anything. The more you order the more we scale and
the cheaper we can make it for you to order, this encourages you to order more etc.. This is a virtuous
cycle that benefits us both. Up and until now our pricing model has been encouraging you to make thin
tiny wispy things.  Larger things and more dense things are
comparatively cheaper for us to make however. There is simply less cleaning
& handling involved per unit of size (and also per $1 in revenue).

Because of this we are able to, for a month and as a test, offer a discount on models that fit the following criteria:

  • only valid for the materials White, Strong & Flexible; Black Strong & Flexible; Summer Blue; Summer Green & Summer Magenta
  • only valid for products ordered from today until the 23rd of July.
  • They have to have a density that is higher than 10%.
  • On a White, Strong & Flexible model you will then pay the regular $1.50 per cubic cm for any model that is less than 20 cubic cm as well as a start up fee of $1.50 per model.So no change there.
  • On  White, Strong & Flexible model larger than this you will pay a start up fee of $1.50. You will also pay $1.50 per cubic cm for the first 20 cubic cms. Any additional cubic centimeters are only $0.75 per cubic cm. 
  • On a Black, Strong & Flexible model there is a $4 start-up cost + 1.78/cm3 for the first 20 cm3 + 0.89/cm3 for any consecutive cm3 over 20cm3
  • On the summer colors there is a  $4 start-up cost + 1.99/cm3 for the first 20 cm3 + 0.99/cm3 for any consecutive cm3 over 20cm3    

You can check density in your 3D modeling application (or totally old
school divide the bounding box by volume of your model).

The discount has been implemented on the site but it might take the site two hours to work through all the galleries.

The discount is over the material price not over the mark up made by the designer so there will be differences in the discount between designers.

This means that large White, Strong & Flexible models have become a lot cheaper on the site for this one month. We hope you guys have fun with this!

    Excellent!! Model volume over bounding box volume is not the density of the model. It is the density of the print volume. In other words, if I print 8 solid cubes 1cm on a side, but put them 2cm apart, then even though they are solid the print density is 8*1cm^3/(4cm)^3 =0.125. Is that correct?

    I was wondering when you’d get around to doing this. In an ideal scenario, where machines worked 100% of the time to specification, you can get away with doing volume calculations for quoting purposes. But it only takes a single failed build due to thin parts to wipe away all the savings that were made on materials by encouraging users to go thin. It also means you get away with higher recycling ratios, etc. Altogether a much more solid (excuse the pun) pricing model for SLS.

    Will this be made permenant if it is successfull?

    It would certianly benifit me as a seller and a buyer if this could be extended (I would probably make another $200+ order if it was). Would this be considdered? :)

      Hi Andrew, if successful we will certainly consider to keep. But as with many of our introductions we first see what the community thinks as that helps us decide what to do next

    Question 1: Could you provide a mathematical equation for the new pricing model, please? I find the English description hard to put into an Excell sheet.
    Question 2: Will putting 3D puzzle pieces closer together in an STL always lower the price? Or at least remain the same?
    Question 3: Will hollowing out 3D puzzle piece as much as possible always lower the price? Or at least remain the same?
    Question 4: If the answer to question 3 is “yes”, then why should I make an effort to make my puzzles more solid?

    Thank you.

      When they say density they mean bounding box over volume. All you have to do to find the density of your model is multiply the volume by the space it takes up (I.e the bounding box). Here is a better way to state this:

      To find the price of your part under the new model The first 20 cu cm are $30, after that any more cu cm are half price. For example take a model that origionally cost $150, subtract the first $30 and then cut the remaining $120 in half leaving you with the new cost of the model which is $90. Essentially any model that is above $30 in price will have a cost deduction as long as it complies with the density standards.

      Hope this helps,

    Due to the positive feedback and fantastic models, Shapeways has decided to reintroduce gold plating as a permanent materials option for the Shapeways community.  With this reintroduction there is a change to the pricing from a flat rate with start up,

    I don’t want to wake any sleeping dogs, but has this been made permanent? It’s well over July 22nd so I’m assuming this was a huge success and you decided to keep the pricing model?

    If I’m reminding you that the price should go back to normal, then please wait until I make my next order ;-) I’ve been on holiday for most of the (actually, the entire) trial period.

    We often get asked ‘at what point does it become cheaper to mass produce and item rather than 3D print it? at which point we have to ask what do you want to make, in what material and to what level of complexity or customization? To approach a need
