Tessa’s Weekly Picks – Merry Metal 3D Printing


Tessa Blokland  

Im Inneren von Gasturbinen herrschen Temperaturen von teils über 1400 Grad Celsius. Je heißer, desto höher die Energieausbeute. Für seine private Spielerei mit gedruckten Bäumen verwendet Rehme eine Legierung mit Nickelanteil. Dieser Spezialstahl schmilzt erst bei rund 1300 Grad Celsius und kann zum Beispiel für die Brenner von Gasturbinen verwendet werden. Für die heißesten Teile der Turbine werden noch widerstandsfähigere Stähle verwendet. Die Druckdaten für seine Bäume bezieht Rehme von der Website grabcad.com.Temperatures inside gas turbines can reach 1,400 degrees Celsius or more. The hotter, the higher the energy yield. The special steel that Rehme uses for his personal project of printing Christmas trees is a nickel alloy. It starts to melt at around 1,300 degrees Celsius and can be used, for example, for the burners in gas turbines. Steels that are even more resistant are used for the hottest turbine parts. Rehme gets the print data for his trees from the website grabcad.com.

You should have bought all your Christmas presents by now, right? Time to turn the house into Christmas!

This might be a pain to an engineer’s eye, but the inside of this 3D printed metal filter takes me into the Christmas spirit. The diffused light shining through the holes of the filter looks similar to angle hair covered lighting on a Christmas tree to me.

I really like this 3D printed metal tree (also top image), designed and made by material researcher Olaf Rehme of Siemens Corporate Technology (CT). The special steel that Rehme uses for printing the Christmas trees is a nickel alloy, normally used for 3D printing gas turbines. Well, I think variety is the spice of life.

Same counts for the materials experts at the University of Birmingham. They created an aluminum 3D printed reindeer, using the same technology as Siemens, direct metal laser sintering.

The last example of 3D printed objects for a Christmas spirit house are these 3D printed metal balls, 3D printed by Admatec on an Admetaflex. The Admetalflex uses Digital Light Processing (DLP) technology to 3D print metal from a resin formulation.
