By these safe dates to many of you, you’ll already have mounted at home Christmas tree. If this is not your case, and you like these dates, we suggest that if you have a 3D printer you to download a tridimensonal model, and if you follow, the advice of Richard Zhang you make do so using filament winding to the maximum without pulling or a single gram of plastic waste.
Professor of computer science at Simon Fraser University, was designing a new way to print objects to not waste plastic and more efficient. His designs have led him to develop an algorithm able to decompose a small pyramidal parts 3D model that allows you to spend less material and save time in the production of the piece.
It comes down to a few pyramids
When a 3D printer places the plastic melted layer of down above, if the form excels in the form of branch, should introduce more material to make it hold. This additional plastic then we have to remove it from the object so do not cross the original form What can be considered a residue that is not worth much. In addition to extract it is not an easy task since it may compromise the structure and its resistance.
With this algorithm you are looking for is Deconstructing an object in a certain number of pyramids they are not perfect but they are pyramidal sufficiently to hold the structure with guarantees and that you do not print more. In addition it is prepared to make several pieces you can paste and create a bigger still, as for example a Christmas tree.
Of course the algorithm can be used for manufacture all kinds of objects but, taking into accounts the dates that are, there is no doubt that print a Christmas tree is very curious. If you have curiosad, Richard Zhang is an expert in modeling and processing of geometric shapes. On its website you have all its publications, some are very interesting.
