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.
