Aluminum Memento

Please enter a valid date

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

This material, with its subtle imperfections, is reminiscent of the Moon or an Asteroid.

Your Memento 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.

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.


This AlSi10Mg alloy has a matte grey finish. There is a subtle sparkle caused by the silicon particles embedded in this material. Certain surfaces can be slightly rougher, while the others are smoother.

How it's 3D printed

Fused and melted using a laser from a bed of metallic powder. The 3D printing process is called selective laser melting.

Fabrication takes place on a build platform with supports to anchor the part. A bed of aluminum powder sits above a build platform. One layer at a time, the powder is melted by a high powered laser. The melted powder is quickly cooled to solidify the metal. To form the next layer, the build platform is lowered and a new layer of powder is distributed with a coater. This process is repeated layer by layer until the part is complete.

Selective laser melting is unique because the high power laser provides enough energy to heat the aluminum powder above the melting point. This process fully melts the powder rather than just sintering it, creating a solid, homogenous aluminum alloy.

This alloy is about 89.5% aluminum, 10% silicon, and .5% magnesium.
