PROCESSING AND MATERIALS EFFICIENCY IN FUSED DEPOSITION MODELING: A COMPARATIVE STUDY ON PARTS MAKING USING ABS AND PLA POLYMERS

There are alot of materials available on market to make a 3D printing part, shuch as ABS, PLA, HIPS, PETG and others. On 3D printing product there are some responses that could be observeb. Some of responses are processing time, mechanical properties dimension accuracy and others. This research is conducted to compare the ABS and PLA efficiency on fused deposition modeling process. Processing time and material consumption are the factor that used in this research to compare the eficiency between ABS and PLA. Processing time, and material consumption were the responses that were measured. The study reports that both of processing time and material consumption using ABS as a printing material was found more efficient compared with using PLA. Printing process using ABS was 2661 seconds, which was faster than using the PLA was 2808 seconds. For the material consumption, show that the average mass of ABS was 7,33 grams compared with using PLA was 8,17 grams. The estimated value of the Axon is always greater than the value of the time recording process and measurement of the mass printing result

STRENGTH AND DIMENSION ACCURACY IN FUSED DEPOSITION MODELING : A COMPARATIVE STUDY ON PARTS MAKING USING ABS AND PLA POLYMERS

Rapid prototyping is a group of techniques used to quickly scale physical parts or assemblies using three-dimensional computer-aided design (CAD) data. The process of 3D printing constructs three-dimensional objects from CAD models, usually by adding lay-ers by a layer of material in a row. Therefore it is also called mak-ing addictive manufacturing. Along with the development of rapid prototyping, there are many choices of materials on the market to make parts of 3D printing. The material can be in the solid filament, liquid resin, or powder. Solid filament FDM technology material is the most commonly used by industry � these materials such as ABS, PLA, PETG, HIPS, and others. In 3D printing products, several var-iables can be observed to produces specific responses desirable. Some of the responses are the efficiency of materials, dimensional accuracy of mechanical, and others. This research was conducted to compare ABS and PLA materials in the fused deposition modeling process. The strength and dimensional accuracy are the response that used in this study. The study reports that ABS has more signifi-cant tensile strength than PLA. The tensile strength of ABS is 7.66 MPa and 1.79 for PLA. PLA found has a more accurate dimension compare to ABS. Both on length and thickness, deviation of PLA lower than ABS. On a length, deviation of PLA was 0.06 mm and 0.86 for ABS. On thickness, deviation of PLA was 0.04 and 0.05 for ABS

HermitCrab Housing: A New Venture

HermitCrab Housing is a website that allows international students to find housing and roommates at U.S. colleges based on preferences such as language, country, and compatibility. This business will create and manage a website for incoming international students to the United States for information on universities, living in the US, and connections to the community. HermitCrab will expand each year to new universities to increase the total available market. In addition, the company will add revenue sources by providing additional services for a premium price. While still in their home country, prospective international students have trouble finding housing near their new university and finding a compatible roommate. There are currently 765,000 international students living in the United States right now. Each year, 215,000 new students will come from around the world to begin a program in an American university. These students all have similar housing problems that could use additional, accurate, and easy-to-read housing information to help them make the most informed decision. We provide unbiased housing information with relevant reviews written by other international students. We also satisfy the needs of international students when looking for roommates through a detailed questionnaire and roommate ranking system

The effect of orientation difference in fused deposition modeling of ABS polymer on the processing time, dimension accuracy, and strength

There are several parameters that must be set before manufacturing a product using 3D printing. These parameters include the orientation deposition of that product, type of material, form fill, fill density, and other parameters. The finished product of 3D printing has some responses that can be observed, measured, and tested. Some of those responses are the processing time, the dimensions of the end product, its surface roughness and the mechanical properties, i.e. its yield strength, ultimate tensile strength, and impact resistance. This research was conducted to study the relationship between process parameters of 3D printing machine using a technology of fused deposition modeling (FDM) and the generated responses. The material used was ABS plastic that was commonly used in the industry. Understanding the relationship between the parameters and the responses thus the resulting product can be manufactured to meet the user needs. Three different orientations in depositing the ABS polymer named XY(first orientation), YX (second orientation), and ZX (third orientation) were studied. Processing time, dimensional accuracy, and the product strength were the responses that were measured and tested. The study reports that the printing process with third orientation was the fastest printing process with the processing time 2432 seconds followed by orientation 1 and 2 with a processing time of 2688 and 2780 seconds respectively. Dimension accuracy was also measured from the width and the length of gauge area of tensile test specimens printed in comparison with the dimensions required by ASTM 638-02. It was found that the smallest difference was in thickness dimension, i.e. 0.1 mm thicker in printed sample using second orientation than as required by the standard. The smallest thickness deviation from the standard was measured in width dimension of a sample printed using first orientation (0.13 mm). As with the length dimension, the closest dimension to the standard was resulted from the third orientation product, i.e 0.2 mm. Tensile test done on all the specimens produced with those three orientations shows that the highest tensile strength was obtained in sample from second orientation deposition, i.e. 7.66 MPa followed by the first and third orientations products, i.e. 6.8 MPa and 3.31 MPa, respectively
