The European space agency have released 3D model files of the Comet 67P/Churyumov-Gerasimenko that the Rosetta space mission plans to land on. We thought that we would give you the opportunity to 3D print this comet for yourself – isn’t 3D printing out of this world.

The associated file is in .OBJ format so you will need appropriate software to deal with it. Our Cubify Sculpt 3D modelling software allows you to import .OBJ files, also many printers allow you to deal with .OBJ files.

The Rosetta satellite is due to make its historic landing on the 12th November 2014 at around 15:30 GMT. So you will need to 3D print your model of the comet and design a suitable model for the Philae. probe (the name of the actual lander that will be released from the satellite) in order to act out this phenomenal event in your own living room. As a quick guide to the conditions that the Philae lander will encounter on the surface:

  • Some Stats

    • Spin axis: Right ascension – 69 degrees; Declination – 64 degrees
    • Water vapour production rate: 300ml/sec (Jun 2014); 1-5 l/sec (Jul-Aug 2014)
    • Surface temperature: minus 68C to minus 43C (Jul-Aug 2014)
    • Subsurface temperature minus 243C to minus 113C (Aug 2014)
    • Gases detected: Water, carbon monoxide, carbon dioxide, ammonia, methane, methanol
    • Dust grains sizes detected: A few tens of microns to a few hundreds of microns

So get 3D printing. This model would be ideal for the classroom for teachers to teach children about comets and give them a real feel for the Rosetta mission, or even for undergraduate teaching. So why not 3D print you own Comet 67P, that currently resides ~464 million km from Earth.

However, bear in mind that we cannot say whether a particular product will be right for the purpose that you intend to use it for. You can return your goods to iDig3Dprinting for any reason within 14 business days following receipt at your delivery address as long as they are in a re-saleable condition. Filaments & resins cannot be returned once opened as once exposed to air these items perish. Downloadable goods and 3D print samples cannot be returned and no refund will be issued. Shipping costs of returned items are paid by the customer A full refund will be issued for unopened items that are returned in their original packaging that are in a "as new" re-saleable condition minus additional costs that are incurred by iDig3Dprinting like payment processing fees, custom duties or charges.

All requests for refunds are subject to inspection by iDig3DPrinting of the returned item. We are not a charity or a lending library. Refunds and returns for faulty items works a bit differently. Faulty goods can be accepted for return upto 60 days from receipt of the goods (However we prefer to offer diagnostics and repair solutions prior to an actual return, its better for the environment). After this time you will need to contact the Manufacturer. A repair or replacement will be issued for faulty goods once they have passed inspection and been found by iDig3Dprinting to be faulty. This is a brief account of our returns policy. For the full terms please see our Terms and conditions page. Content on the Terms and Conditions page supersedes this content.

How to raise a return request

  • email idig3dprinting at and we will issue a Return Authorization Number (RAN).
  • send the goods back in their original packaging.
  • Once we receive the goods back we will then check them and if everything is as it should be be will issue a refund.
  • If appropriate Refunded payments will then be issued using the original payment option. The time it takes to land in your bank account is determined by the payment gateway used not us.

The main thing is please communicate with us. We are not omnipotent! We can be quite flexible but this is built upon a foundation of mutual respect between our customers and iDig3Dprinting.

Great service, very quick to answer queries and resolve any problems. Reliable and affordable.
First class service and support, purchased some spare parts for my printer and they were glad to help with an unrelated problem I was having with the printer, even though it was not supplied by iDig , I would recommend them without hesitation.
Have had a lot a of problems setting up a 3d printer at our school, idig3d printing contacted me through a forum and have been brilliant ,giving advice and guidance. Thank you
