Background
Inspirée par la Metal Delta RepRap v1 as pour but de proposer ine imprimante 3D Metal economique mais basée sur le procedé TIG (GTAW) qui as le potentiel d'etre plus precis et permet d'utiliser des postes a souder Baguettes economiques basés sur la technologie inverter.
L'objectif de ce concept d'imprimante est de revenir a moins de 1000€ et de produire des cordons de soudure inferieur a 2mm.
Ce concept d'imprimante as été developé en deux mois grace au support du FabLab Artilect a Toulouse
L'imprimante n'est pas encore operationelle mais des tessts de depose de metal sur des plaques de metal ont été effectués ainsi que quelques tests de superposition de couches.
Conception
L'imprimante est basée sur la structure de l'Enlarged Rostock[1] qui est issue de la Rostock de Johann Plus de details a venir
Fournitures
Composants sur la machine a ce jour:
- Welding source: GysMi 80p 120 (any inverter based MMA power source should do, it might be advised to go up to a 130A one ) (120€ to 250€ for simple MMA sources) - Round Shaft: 12mmx1000mm Z-12-1000A x 6 -> 90€ Obtained From HPC Europe - Linear Bearings 12mm KB-12-WW x 6 -> 67€ Obtained from HPC Europe - Belt 2m T2.5 x3 & Pulley 16 tooth x3 -> 75€ + 19€ Obtained from eMotion Tech - Gen 7 V1.4.1 board x 1-> 145€ (the more recent Ramps FD + arduino due might be a good choice ) - Nema17 400 step/turn x3 -> 47€ Obtained from Selectronics (for the 3 axis) - Nema17 200 step/turn x1 -> 16€ eMotion Tech ( for the extruder ) lower steps is better for rapid retract - Carbon rods -> diam 8 Kite frame from Decathlon - Donut magnets x12 -> 12€ ref: R-15-06-06-N from Supermagnete - Steel balls diam 12.7 x12 -> 4€ ref:K-13-N from Supermagnete - USB-A Female plugs x4 -> 4€ from Electronique-Diffusion - USB-B Female plugs x4 -> 4€ from Electronique-Diffusion - USB printer Cable x4 -> 12€ from Electronique-Diffusion - 9pin SubD conector Male & female -> 2€ from Electronique-Diffusion - Bearings x5 -> From roller blades 5€ - Recuperated Stoneware tile -> 0€ (Not adequate a conductive material will be better to reduce deformation)

Conponent identified for the planned upgrades:
- Welding plate -> Thick copper or aluminium plate - 24V power supply -> for solenoid valve & motors - 24V solenoid valve -> for argon managment - 10K Digital potentiometer -> AD5175 or similar to control welding power source - Inductive Curent sensor -> to measure welding current - Optocouplers -> to isolate electronics from the welder control to the printer control - HF ignition system -> Coil, condenseurs, etc...
