Advantages of 3D printing
In 3D printing there is no need for a mold like in traditional plastic and metal manufacturing,
which saves time and money. This is especially beneficial when making prototypes and
models. Product ideas can easily be changed and updated. The complexity of a product is
also less of a hindrance when using 3D printing. Instead of producing several parts and
fastening them together, as in traditional manufacturing, it might be possible to produce the
part in one piece with 3D printing. Holes for screws can be included in the cad-drawing in-
stead of drilling them.
·
Design and prototyping
As there is no need for molds, tooling and expensive use of factory machinery lines,
3D printing is the ideal choice for the prototyping process. Models may be produced
and changed frequently without all the hassle that is the case with traditional manu-
facturing.
·
Complex structures
Additive manufacturing allows complex structures such as hollow areas and shapes that
are difficult or impossible to make with traditional manufacturing. This feature enables
lighter parts, for example in aircrafts.
·
Customization
This is 3D printing's strong point. Unlike mass production, It does not differ much
in cost to produce one or thousands of units. Additive manufacturing do not require
tools and molds which makes it easier to change and alter designs. This makes it a
perfect alternative for customized products in health care, promotion, figurines etc.
·
Less waste
There is considerably less waste material in additive manufacturing than in subtract-
ive manufacturing, especially when it comes to production of metal products. For
some cases in traditional manufacturing it is estimated that after casting molds, for-
