3 boyutlu yazıcı teknolojisi son yıllarda giderek yaygınlaştı ve bu da
matematiksel modellerden, elle tutulabilir somut gerçek nesnelerin üretimini,
şimdiye kadar hiç olmadığı kadar çok kolaylaştırdı. Bu çalışmanın amacı da
eriterek üst üste yığma metodunu kullanan bir masa üstü 3 boyutlu yazıcı
kullanarak, matematiksel denklemlerden yola çıkarak onların 3 boyutlu
matematiksel modellerini oluşturmak ve oluşturulan bu modelleri de dijital
olarak 3 boyutlu yazıcı ile üretmektir. Matematiksel denklemleri kullanarak 3
boyutlu matematiksel modellerin oluşturulması işlemi K3DSurf yazılımı
kullanılarak gerçekleştirildi. 3 boyutlu matematiksel modeli oluşturan x, y, z
koordinatlarına ait veriler daha sonra üretimi gerçekleştirecek 3 boyutlu
yazıcının tanıdığı format olan “.obj” dosya formatına dönüştürüldü. MakerBot®
firmasının MakerWare™ adlı katmanlara ayırma programı kullanılarak üretilecek
model istenilen kalınlıktaki katmanlara ayrıldı, baskı kafasının x-y ekseni
boyunca yapacağı hareketler hesaplattırıldı ve bu veriler “.gcode” formatına
çevrilerek bir sd karta aktarıldı. Örnek çalışma olarak ise, Diamand denklemi,
belirlenen sınır şartları arasında değerler verilerek 3 boyutlu matematiksel
modeli oluşturuldu ve Flashforge Creator modeli masaüstü 3 boyutlu yazıcı ile
dijital üretimi yapıldı.

Digital fabrication of a real object from a mathematical model by using 3D desktop printer

Öz

3-D printing technology is becoming widely available and can help to
produce tangible solid physical objects from mathematical models much easier
than ever before. The aim of this paper is to construct mathematical models
from mathematical equations and to fabricate real solid objects digitally from
mathematical models by using a 3-D Fused Deposition Modelling (FDM) printer. Formation of 3D mathematical models using mathematical equations was
performed using K3DSurf software. The data for the x, y, z coordinates that
form the 3-D mathematical model are then converted to the ".obj" file
format, which is the format recognized by the 3-dimensional FDM printer that
will realize the fabrication. Using MakerBot®'s slicing software MakerWare ™,
the model to be fabricated is sliced into layers of desired thickness,
movements of the printing head along the x-y axis are calculated, and this data
is transferred to a secure digital (SD) card in “.gcode” format. As a case
study, a 3D mathematical model was obtained by assigning values to the Diamand
equation between the boundary conditions, and it is digitally fabricated by
using a FlashForge Creator desktop FDM 3D printer.
