Experimental and Thermal Analysis of Desktop FDM 3D Printers "Ender 3" and "CR-10S Pro" Hot Ends

Abstract

Nowadays, the desktop 3D printers are common in computer aided manufacturing and widely used in multiple applications across homes, offices, and in several business sectors, etc. A wide variety of filaments like PLA, ABS, PETG, TPU, etc. are now being used in Fused Deposition Modeling (FDM). These filaments require different temperatures to print. FDM is a process in which a material in its filament form is melted and deposited layer by layer to form the required object. The hot end of a printer plays a crucial role in the melting of these filaments for printing. It is a major component of a 3D printer, where the filament is brought to a semi-solid state, to extrude and deposit the filament in layers. In this research study, the hot end of "Ender 3" and "CR-10S Pro" are modeled using Computer Aided Designing software, and thermal analysis using Finite Element Analysis, is carried out by applying the maximum printing temperature of PLA for the two printer hot ends. To optimize the problem of wide temperature gradient which often results in clogs and jams across the hot end, the design of heat sink is modified to maximize heat dissipation. Alongside, the simulation result is also compared with manual experimental readings.

Smartvessel: A New Extinguisher Prototype Based on New Materials and IoT Sensors

“…On the other hand, an accessory was designed to be attached directly to the hook of the extinguisher to measure its weight. It consists of a piece made of Polyethylene Terephthalate Glycol (PETG) [ 27 ] and was printed in 3D with an Ender© 3 pro printer (Creality 3D, Shenzhen, China) that had a nozzle diameter of 4mm, accepts 1.75mm filament and a print volume of 220 × 220 × 250 mm [ 28 ]. This piece can be hung from a standard hook that is anchored to a wall and serves as an interconnection with the equipment, being compatible with any extinguisher and commercial solution ( Figure 4 ).…”
