If you are feeling creative for Christmas tired of old tree decorations, why not try creating your own?
With just a 3D printer and a proprietary SOLIDWORKS software you can create it at home so you don’t have to go out in cold weather, just a minced meat pie, start SOLIDWORKS and set it up. next!
From the models used in SOLIDWORKS Flow Simulation software we have created our own car using the MakerBot Replicator 3D mini printer. Some modifications are required prior to printing, possibly creating a traditional sleigh design first, a circle created so that the ribbons can be threaded to hang onto the trees, the slopes at the bottom and struts also need to be thick to meet the required lift for the model, and also have hook tips for the reins, these models are scaled down below 100mm to fit in the printer.The improved models are then passed through the SOLIDWORKS Flow Simulation add-on software with the same parameters used as before, to ensure a fair comparison. The image below shows a oblique crash wave formed around the cone apex, which interacts much less ambient air and has a pressure of about 315kPa at the edge of the head, while the traditional design has a pressure of 889kPa.
Thanks to the addition of a roof, the new design is able to cope with turbulent internal flow and thus significantly reduced traction.
