(work in progress blog) I want to tell my experience and story about the creation of MELS 3D LABS Articulated Seahorse. Of all the Articulated designs, this has a unique story and place among them all. Early 2024, i was researching for an articulation no other designer has ever made. It should be an interesting creature as well, my research led me to seahorse, a beautiful creation of nature. THE SCULPTING My sculpting workflow evolved over the years, a systematic, hence its time consuming but foolproof approach to perfection. Typically i sculpt 2-3 days straight, mostly skipping breakfast as i get hyper obsessive. The sculpting path : Typically i could create a link and the body section, where then i can duplicate it, then scale it down and keep duplicating it up to the tail. That would save a lot of time and effort. But for the seahorse, This wasn’t the case. The body is curved, hence even after duplicating, each link has to be precisely sculpted to preserve th...
The project started as a 1 meter Cartesian Cube. But for easy transportation around the house, I had to reduce the printer width to 83 cm from 1 meter. Printer details can be found below ; Max tested printing speed : 150mm/s Best results as of now : 75mm/s with 550 acceleration & 0.04 junction Deviation Printer dimensions : Length : 120 cm Width : 83 cm Height : 83 cm Current Print Dimension : 60 × 60 × 50 cm Print Dimension upgradable : 120*83*83 cm Endstops set to : 48x * 38y * 28z cm Firmware : Marlin 2.0.6.1 upgraded to 2.0.8.2 with SKR2 Steps per unit A4988 (100, 100, 2600, 95) DRV8825 (200, 200, 5200, 190) Iinear Advancement K = 0.22 Baud 250000 # printing Material (All metal) [PLA, ABS, Nylon, ASA, TPU etc] # 1.75mm filament # 100k ntc b 3950 Thermistor # 12v 40w heating cartridge # E3D V6 All Metal J-Head Hotend Extruder PID Tuning 195°c Kp : 41.88 Ki : 7.41 Kd : 59.18 185°c Kp : 42.65 Ki : 7.23 Kd : 62.90 # Fat Nema extreme Extrusio...
