in different design stages. In this work it was develop-
ment an important study in open source desktop 3-D
printer considering an inclusion a new interchange-
able head since this head has the weight significantly
higher than the head showed in Figure 1. The results
obtained from structural analyses were:
•
The deflections presented significantly values com-
pared to stress actuating, consequently cannot
neglected in operational conditions. There were
reductions of the deflections of the 11.64% (case 2)
e 70.85% (case 3) for X-Y axes; increase of 1.27%
(case 2) and reduction of 72.42% (case 3) for Z
axis and finally in the structure for case 2 there
was a reductions of 5.66% and 88.89% considering
cases 2 and 3, respectively.
•
Considering the mechanical ...
