data. Rapid Prototyping allows the visualization of a
three-dimensional image into a native three-
dimensional object that has volume. Some of the
current Rapid Prototyping methods are: (Djoko
Kuswanto, 2017)
1. Stereolithography (SLA)
2. Direct Light Processing (DLP)
3. Continuous DLP (CDLP)
4. Selective Laser Sintering (SLS)
5. Both Selective Laser Melting (SLM) and Direct
Metal Laser Sintering (DMLS)
6. Electron Beam Melting (EBM)
7. Multi Jet Fusion (MJF)
8. Fused Depsition Modeling (FDM)
An inexpensive and often used technique is the
so-called fused deposition modelling (FDM) firstly
established by Stratasys (Redwood, 2018), in which a
thermoplastic polymer is molten in an extruder
nozzle, and the fluid material is deposited on the
printing bed line by line, building the first layer of the
planned object. After finishing the first layer, the
printing bed is lowered, and the next layer is printed
on top of it until the highest layer of the object is
finished (C. K. Chua, 2010). The materials used for
printing with the FDM technology are, e.g., ABS
(Acrylonitrile butadiene styrene), PLA (polylactic
acid) and several others with diverse physical and
chemical properties.
3.2 Indonesian Decorative Pattern
(Kawung Pattern)
Decorative variety is one form of art that is
very attached to the identity of the Indonesian nation.
Various kinds of decorations can be found in
Indonesia, whether in batik cloth, woven fabric,
songket, temple, and praying place. Types of
decoration are generally classified into 4 parts,
namely geometric, flora, fauna, and figurative.
Kawung motif is included in Indonesian geometric
Pattern. The following are the types of kawung
motives and their pattern elements:
(Sarwono, 2005)
1. Kawung Sari
The main ornaments are oval-shaped
spheres, and on each part of the kawung pattern
are given a line that divides into two parts as if
they resemble the shape of a broken coffee fruit.
This kawung pattern is often also referred to as
Kawung Kopi.
2. Kawung Sekar Ageng
The main ornament is in the form of four
oval spheres that have changed into a square or
square shape. In each main ornament there are
three lines (sawut) and three points (cecek).
3. Kawung Sen
The main ornament in the form of four oval
spheres composed by the main is arranged in the
direction of a diagonal oblique angle as if the
kawung pattern is limited by curved lines.
4. Kawung Pecis
The main ornaments are oval spheres, and
are smaller in size compared to the main
ornaments in Kawung Sen and the batik pattern
in Kawung Pecis are rather oval square. The
pattern of Kawung Pecis consists of two dots
(cecek) contained in the main ornament.
5. Kawung Beton
The shape of the ornament on this motif is
very large, and somewhat rounded, but still in an
oval shape. Isen motif found in the main
ornament in the form of cecek (dots) with a large
size and in the middle there is a small circle
shape. The shape of this circle
divides into four parts as if the main
ornament is crossed.
6. Kawung Semar
The main ornament is in the form of four
oval spheres with a large size as in concrete
Kawung, but inside the main ornament is a
smaller oval shape. Isen pattern on Kawung
Semar consists of the form of cecek (dots) found
in the circle inside the Kawungan sphere. In the
middle of the main ornament is a rhombus-
shaped motif that is filled with cecek (dots) and
several circular shaped dots.
7. Kawung Buntal
The main ornaments in the form of a
mixture from Kawung Pecis are combined with
floral pattern. The flower pattern found in the
Kawung Puffer are in the form of kenikir
flowers, so the shape of the mixture of motifs is
characteristic of the pattern of Kawung Buntal.
Isen batik motif in Kawung Buntal consists of a
small oval round shape which is divided into
two parts placed in its main ornament, and a
small, medium and rather large rhombus shape
placed in the middle of the main ornament.
8. Kawung Kembang
The main ornament in the form of four oval
spheres is made to resemble the shape of a
flower (flower), so this motif is called Kawung
Kembang.
