Abstract

Remanufaktur adalah proses pemulihan barang bekas yang memberikan preservasi tertinggi terhadap nilai tambah produk originalnya, proses ini mentransformasikan barang bekas menjadi “seperti baru” dan seringkali dikembalikan ke pasar dengan garansi yang ekuivalen seperti produk baru. Praktik remanufaktur ini dapat memberikan dampak positif terhadap lingkungan karena dapat mengurangi limbah yang dibuang ke tempat pembuangan akhir. Namun remanufaktur juga memiliki banyak tantangan, tidak hanya dalam aspek teknikal dan operasional, tetapi juga pada aspek strategi dan desain. Makalah ini menyajikan pendekatan konseptual berdasarkan tinjauan literatur untuk menjawab tantangan remanufaktur dalam rantai pasok lingkaran tertutup, serta mengusulkan strategi dan desain implementasinya. Pendekatan yang digunakan adalah qualitative content analysis untuk mengidentifikasi berbagai konsep dan membagi dalam kategori yang sesuai. Hasil analisis menunjukkan bahwa implementasi remanufaktur dalam rantai pasok lingkaran tertutup dapat diterapkan dengan penentuan motif dan pendorong, dimensi keputusan remanufaktur, strategi implementasi remanufaktur, desain produk dan proses, serta desain jaringan.

Abstract

3D printing is a manufacturing process widely used in the 4.0 Industry era. One of the concepts of 3D printing is to make prototypes, whether it is for industrial purposes or studying purposes. Knowing that a prototype is only needed in the early stages of any process, it is bound to be redundant in a short time; thus, the plastics used to prototype using the 3D printing technology are now labeled as waste. Since most plastics used for 3D printing are thermoplastics, they can be recycled to live another purpose. This research aims to design a crusher dedicated to processing 3D printing waste as the first step towards recycling these wasted materials. This step encourages students to comprehend the process of designing and manufacturing such equipment while also opening doors for the faculty towards recycling 3D printed plastics. The designing process consists of surveying the materials commonly used for 3D printing, calculating the machine elements, choosing the mechanism needed to destroy the material, and designing a model from the calculations. The outcome of the design is a device that can crush and destroy PLA (Polylactic Acid) and ABS (Acrylonitrile Butadiene Styrene) plastics into pieces ready for recycling

Abstract

Teknologi 3D printing atau yang umum disebut sebagai additive manufacturing merupakan salah satu metode rapid prototyping yang saat ini semakin luas digunakan. Acrylonitrile butadiene styrene (ABS) merupakan salah satu jenis material yang penggunaannya cukup masif dalam teknologi 3D printing. Penelitian ini menggunakan metode desain eksperimen orthogonal arrays L9 ( ). Adapun parameter proses yang digunakan adalah temperature nozzle, temperature base plate/bed dan orientasi, serta dengan tiga variasi level pada setiap parameter proses (230oC, 240oC, 250oC, 90oC, 100oC, 110oC, 0o, 45o, 90o). Penelitian ini bertujuan untuk mencari parameter proses yang paling optimal terhadap hasil respon waktu pengerjaan, sifat mekanik kekuatan lentur, dan akurasi dimensi. Parameter tersebut digunakan untuk kombinasi metode Taguchi dan PCR-TOPSIS dalam menyelesaikan persoalan multirespon. Berdasarkan hasil analisis ANOVA, parameter dengan level yang menghasilkan respon gabungan paling optimal adalah terletak pada spesimen kondisi ke-3, yaitu dengan nilai temperature nozzle sebesar 230°C; temperature base plate/bed sebesar 110°C; dan arah orientasi printing sebesar 90°. Hasil analisis dari PCR-Topsis terhadap 3 parameter proses menunjukkan bahwa parameter yang memiliki pengaruh yang paling tinggi secara berurutan adalah orientasi 33%, temperature base plate/bed 28% dan temperature nozzle 18%.

Abstract

The use of manufacturing additives or commonly known as 3D Printing is increasingly widespread. The type of additive manufacturing that is often used is FDM (Fused Deposition Modeling). The most frequently used filament for prototyping and research is PLA (Poly Lactide Acid) type filament. This research will use multiresponse optimization, namely Taguchi-grey. So that later in this study will use 9 conditions with 3 parameters and 3 levels. The parameters used were orientation (0 °, 45 °, 90 °), nozzle temperature (190 °C, 200 °C, 220 °C), and bed temperature (0 °C, 30 °C, 60 °C). The purpose of this study was to find the most optimal parameters based on response time, dimensional accuracy and tensile strength. Based on analysis using Taguchi-grey, ANOVA results show that the most significant contribution is nozzle temperature (51%) and orientation (42%). From ANOVA, it can be seen that the most optimal condition is condition 6 which has been printed, with orientation of 45°, nozzle temperature of 220°C and bed temperature of 0°C.

Abstract

Additive Manufacturing (AM) has emerged as a rapidly developing technology with applications ranging from product visualization and prototype fabrication to actual production. Various types of AM are available on the market, broadly categorized into industrial-grade and consumer-grade machines. This study focuses on consumer-grade printers, which are more affordable and widely accessible. Among these, the two most commonly used technologies are Material Extrusion (ME) and Vat Photopolymerization (VP). While the performance of ME printers has been widely investigated, comparative studies between ME and VP remain limited. This research provides a performance comparison of the two technologies. The findings indicate that VP printers outperform ME in terms of printing speed and energy efficiency. On the other hand, FDM printers offer advantages in material cost and dimensional accuracy in the Z direction. Furthermore, the study examines the potential of consumer-grade printers to support automotive product prototyping efficiently and practically.

Abstract

Additive manufacturing (AM) technologies can generally be divided into industrial-grade systems and consumer-grade machines, the latter being more cost-effective and accessible to a broader user base. Within the consumer segment, the most prevalent methods are fused deposition modelling (FDM) and LCD-based vat photopolymerization. Although FDM has been extensively studied, direct performance comparisons between material extrusion (ME) and vat photopolymerization (VP) remain relatively scarce. This study addresses this gap by evaluating the mechanical behavior of both technologies. The results show that LCD-based printing demonstrates superior performance in certain mechanical aspects (elongation), while both entry-level materials achieved comparable tensile strengths of approximately 31.5 MPa. In contrast, the flexural strength was higher in the specimens produced by ME, indicating that each process carries distinct advantages depending on the application.
