What Wouldn't it Take to 3D Print a 1:1 Scale Loss of life Star?

A 3D printed Loss of life Star in its authentic dimension and glory – that’s a 3D printing undertaking of galactic proportions. All3DP’s creator Franklin Houser has crunched the numbers.

So, what does it take to 3D print a 1:1 scale Loss of life Star? The query I’ve requested myself is determined by a number of variables. For simplicity, I’ll solely be specializing in materials prices, and the time wanted to finish the duty in addition to a couple of totally different situations. One essential issue is the ratio between the stable materials and open area inside the battle station as we might solely 3D print the stable parts.

Get Ready for a Massive Cargo of Filament

3d printed death star

comparability could be a skyscraper. The Burj Khalifa in Dubai is at the moment the tallest man-made construction on this planet. A big entrance foyer and 57 elevator shafts make for a very good illustration of hangar bays and reactor shafts within the Loss of life Star. I did some fast analysis and came upon that the Burj Khalifa has a quantity of roughly 2,600,000 m3 primarily based on the whole accumulative floor space per particular person storey and its top. Contemplating that the skyscraper was constructed utilizing bolstered concrete at 2400 kg/m3 on common, and has a complete empty weight of 440000 metric tons, the constructing consists of roughly 10% stable constructing supplies and 90% air-filled area. Surprisingly sufficient, when you had been to 3D print a stable 1:1 scale duplicate of the Burj Khalifa out of basic ABS filament, it might be heavier than the true factor.

Now let’s assume that 10% of the 3d printed Loss of life Star’s quantity was additionally comprised of stable constructing materials.

Based on Wookieepedia, the primary Loss of life Star was a spheroid with size, width, and top measuring 120 km making it pretty much as good as fully spherical. Excluding the very fact that there’s a conical indent on its floor for the tremendous laser, able to destroying whole planets, the quantity of the primary Loss of life Star got here to roughly 905,000 km3. That’s much more than the Burj Khalifa. That implies that the whole stable quantity of the Loss of life Star was 90,500 km3.

Utilizing ABS filament, which has a density of 1.08 g/cm3 on common, we would want 97,740,000,000,000,000 kg of it. That’s ninety-seven quadrillion, seven hundred forty trillion kilograms.

How Lengthy Does it Take to 3D Print a Loss of life Star?


Most 3D printers can print at a pace of 24 mm/s not less than. At that price, it might take somewhat greater than 119,572,000,000,000 years to finish the 3D printed Loss of life Star. We would as properly watch the universe develop chilly whereas we’re ready for our Loss of life Star to develop into totally armed and operational. The quantity of filament wanted would at the moment value three,323,000,000,000,000,000 Euros if purchased in zero.75 kg spools with no low cost.

These numbers are extraordinarily enormous, and realistically, the duty would by no means be doable utilizing a desktop 3D printer, except it might print at a pace of 143487 m3/s at which price our 3d printed Loss of life Star could be completed in 20 years. That’s how lengthy it took the Galactic Empire to construct the primary one.

ABS or PLA for a 3D Printed Loss of life Star?


There are nevertheless a couple of extra elements to think about when planning to 3D print a Loss of life Star. For one, we must assemble a mechanism to maneuver the printer alongside the floor of what has already been printed, for the reason that whole Loss of life Star wouldn’t match contained in the tiny field of a desktop 3D printer. And, your entire building must happen in area, since it might be extraordinarily troublesome to blast the completed Loss of life Star into earth’s orbit.

Secondly, we would want some energy provide; most likely solar energy. Lastly, ABS filament begins to get mushy round 105°C and melts at beneath 300°C. If the Loss of life Star received wherever close to a star throughout its lifetime, it might merely flip into a large ball of molten ABS or deplete. There are a lot of extra elements that might limit the development of such a Loss of life Star with as we speak’s know-how.

Conclusion: Is it Value it?

In case you had the time and the cash, then positively; as a result of who wouldn’t wish to cruise across the galaxy of their very personal Loss of life Star? I can consider one benefit that might come of the extraordinarily lengthy print time. If stored in full secrecy, the length of the construct may simply outlast the existence of the Insurgent Alliance or The Resistance, thereby tremendously rising the probabilities of it ever ageing and even being accomplished.
