Steel & Titanium Mementos

Please enter a valid date

Celebrate the most important event in your life with your personal Solar System. 

Your Memento, with a beautiful Meteorite aspect, will be the most precise and accurate depiction of the Solar System commemorating the personal date of your choosing. 

The latest NASA data and algorithms are used to compute precisely the positions of the planets and their orbital paths.

Made to order. Please allow up to 30 business days for the production. Produced in Europe. Customs fee may apply. 

We believe our designs are the best on the market because we have combined scientific data with an artistic dimension to make beautiful yet accurate renderings. We use the latest NASA data and algorithms to compute precisely the positions of the planets and dwarf planets, as well as their orbital paths. We have tested our output extensively against results available on JPL's systems because we strive for the best quality and accuracy. 

We then process the numbers in a 3d projection to generate a depiction of the Solar System that is unique to the date you requested. No two different dates produce the same design, that's why SpaceTime Coordinates products are so distinctive and personal. We generate the graphics uniquely and carefully for each order we receive to make sure that your STC item represents *your* special place in space and time.

Stainless Steel

Made with high-grade & high-strength steel (316L).

Raw Steel is treated with a blasting operation after printing. Outer surfaces, inner areas and sunken areas get a matte look. This is the gentlest post-processing finish with the highest level of detail. 

Polished Steel undergoes a mechanical polish. Outer surfaces get a polished look, whereas the inner areas of your model and sunken areas will appear darker and more matte.


This TiAl6V4 alloy doesn’t look like the traditional shiny milled Titanium. Instead it’s a bit grayer and more matte with a slightly rougher and less defined yet precise surface.

It is the strongest material that can currently be 3D printed. 

How it's 3D printed

Steel: Indirect Metal Printing us special 3D printers to deposit small drops of glue onto layers of stainless steel powder, one layer at a time, until the print is complete. It is then sintered in an oven at 1300°C. 

Titanium: Metal 3D Printing – also known as Direct Metal Laser Sintering (DMLS) and Select Laser Melting (SLM) – a laser-based technology that uses powdered metals. Similar to Laser Sintering, a high-powered laser selectively binds together particles on the powder bed while the machine distributes even layers of metallic powder. Once complete, the part undergoes heat treatment.


Stainless Steel contains Nickel. Some people may have a Nickel allergic reaction, but the amount of Nickel is so low (10%) it often does not trigger an allergic reaction.

Steel may tarnish.
