Open-source 3D printer hs een one of the populr choices in fricting 3D models. This technology is esily ccessile nd low in cost. However, severl studies hve een mde to improve the performnce of this low-cost technology in term of the ccurcy of the prts finish. This study is focusing on the selection of slicer mode etween CurEngine nd Slic3r. The effect on this slicer hs een oserve in terms of ccurcy nd surfce visuliztion. The result shows tht if the ccurcy is the top priority, CurEngine is the etter option to use s contriute more ccurcy s well s less filment is needed compred to the Slice3r. Slice3r my e very useful for complicted prts such s hnging structure due to excessive mteril which ct s support mteril. The study provides sic pltform for the user to hve n ide which option to e used in fricting 3D model. 1. Introduction The first prgrph fter heding is not indented (Bodytext style). 3D Printing technology hs een widely used since the expirtion of FDM technology few yers go [1]. The first open-source 3D printer hs een developed y Jones et l nd the first model ws nmed s Version I Drwin [2]. Nowdys, the populr open-source technology is including MkerBot nd Ultimker which commonly used use polymer mterils such s crylonitrile utdiene styrene (ABS) nd polylctic cid (PLA) [3]. The cost of this technology is round $1500 to $5000 which is quite ffordle [3]. Low-cost is one of the fctor tht this open-source 3D printing hs een chosen to fricte the 3D models. However, the performnce of open-source 3D printer still in dout where study ws done on the dimensionl ccurcy using low-cost 3D printer shows differentil in dimension to the ctul vlue [4]. Also other study showing 20% different etween the finish prts nd the CAD dt [5]. Despite of this drwck, some study ws done to improve the performnce y investigting the process prmeters to increse the ccurcy of the finish prts [6]. Other study ws done on improving the nozzle with specific die ngle to improve the ccurcy s well [7]. Cost lso hs een study y compring severl 3D printing technologies to give n ide in choosing the right prmeters nd technology depending on desired specifiction [5]. This present study focus on compring the slicer mode to oserve the different on the performnce. The slicing option is to convert the design model from CAD dt into redle code to strt the printing process. So fr, there is no study hs een done regrding the selection of slicer mode option nd their effect on the finish prts. This study will oserve the two slicers which re CurEngine nd Slic3r to see the effect on the finish prts which cn e used to improve the product.

3 2. Methodology A new open-source ws developed in the l consist of micro-controller (Arduino), hving five stepper motor for x, y, z xes nd for the feeding filment. The 3D printer using led screw for ll the three xes nd lso single power supply. The uild dimension is 21mm x 21mm x 30mm. 2.1 Slicing Method In this reserch, two types of slicer hve een used for the comprison which re CurEngine nd lso Slic3r. The function of this slice is to convert the design model from CAD dt into redle code such G-code for the printing process. This process need to e done fter setting up the prmeters such lyer thickness, percentge infill, printing speed nd so on. The slicing softwre will utomticlly convert ll the dt into redle code for the extrusion process. 2.2 Smple Friction In order to compre the slicing method, two smples were designed using Autodesk Inventor Softwre (Autodesk, USA) nd converted into stndrd tringulr lnguge (STL) formt. The first smple is quite simple with stright nd curve design s shown in Figure 1() while the second smple more complicted with comintion of roundness shpe, chmfer, fillet, nd tiny hole s depicted in Figure 1(). Figure 1. () Smple 1 () Smple 2 The process prmeters were fixed for oth slicer including lyer thickness of 0.3 mm, shell thickness of 1.2 mm, printing speed of 60 mm/s, nd rectiliner fill pttern. 2.3 Dimensionl Accurcy Mesurements The dimension ws mesured only for smple 1 using vernier clliper. Severl dimension on the smple prts ws tken to compre the differences for oth slicer CurEngine nd Slic3r. 3. Results nd Discussion The study focus on two spects which re the dimensionl ccurcy nd the surfce visul of the finish prts. There were two prts from smple 1 were fricted y using oth slicer. This condition ws pplied to the smple Accurcy Mesurements Two prts from smple 1 were printed using CurEngine nd Slic3r slicer s shown in Figure 2. Both slicer ws compred nd the dt were recorded in Tle 1. Figure 2. Printed smple 1 () Slice with CurEngine; () Slice with Slic3r 2

4 Tle 1. Dimension mesurements for oth slicer Nominl CurEngine Slic3r (mm) Dimension (mm) (mm) Bsed on the mesurement of the dimension, there is slightly different etween slice with CurEngine nd Slic3r. Overll, the CurEngine give much etter ccurcy round 0.1 mm. Some of the feture shows quite significnt different round 0.2 mm. 3.2 Surfce Visul The smple 2 design ws exported to Repetier-host softwre. The first model ws sliced using option of CurEngine. The second model from the sme smple 2 ws sliced using Slic3r. To compre oth slicer, two models from smple 2 were fricted. By visulizing the surfce of the finished prts, there is difference in terms of the smoothness of the certin prts. If we oserve crefully, especilly in roundness shpe nd the two-tiny hole showing some of the excessive mterils y using Slic3r while the CurEngine just slightly excessive mteril. This clerly cn e seen in Figure 3 elow. Figure 3. () Excessive mteril in tiny hole () Excessive mteril in roundness shpe For the finished prts tht slice using CurEngine, the model smoother compre to the Slic3r nd just slight excessive mteril s shown in Figure 4.

5 Tle 2. Comprison etween CurEngine nd Slic3r Printing Spec CurEngine (mm) Slic3r (mm) Printing time 38m 19s 35m 23s Lyer Count Filment needed 6230 mm 6968 mm The finding from this study is tht if the models need more ccurcy, the etter slicer option ws to use the CurEngine. In ddition less time required nd sve more filment which is less cost s shown in Tle 2. Besides, the finished prts re lso good enough which is within the rnge of 0.1 mm. Menwhile, if using Slic3r, more filment ws needed compred to the CurEngine which shows lot of excessive mterils ppered on the finish prts. In terms of ccurcy, the Slic3r less ccurte due to excessive mteril. However, Slice3r mye is the est option for the complicted prts which involve lot hnging structure ecuse the excessive mteril cn e used s support mteril. 4. Conclusion Both slicer etween CurEngine nd Slic3r hs een compred in terms of dimensionl ccurcy nd the surfce visuliztion. It shows tht CurEngine contriute more ccurcy nd less filment is needed for printing the prts. However, the Slice3r cn e used for prts tht possess lot of hnging structure. Overll, the study is providing the pltform for the user to hve mny options ville so tht they cn mnipulte to hve ny output tht they wnted depending on the spec. 5.
