Quote Can I can feel that Gada prize calling?! I hope so. (You'd want to put the files in the wiki, then.) (It's a good name.) Set up the wiki page as suggested to the letter! Probably will enter the Gada prize if I can manage my time.by Wiperman - Delta Machines
Hi, I've been looking into this for about 4 months now and here is a summary of what I think is the goings on. 1. x-y tables are not a problem 2. metal power supply is plentiful and cheap with a huge variety of different metals available 3. A blower is needed to blow powder to a surface - hardly a challenge 4. A roller needed to roll over the powder laid on the construction surface - hardly a cby Wiperman - MetalicaRap
Hmmm... extruding molten lead would be better than extruding molten plastic because of the viscosity!! I take on board your point about having short section of thin nozzle to keep the pressure down. Never occurred to me! I should be able to grind the needle after fitting to 1mm or less. But that sounds like wasted effort because it would be easier to drill with say a 3mm drill most of the way aby Wiperman - Plastic Extruder Working Group
I am working on a delta robot 3D printer. This is a light weight device costing about £20 in parts (excluding electronics). I build delta robot already But now I need a really light weight extruder. I'm thinking of a syringe needle and a light weight SMT temperature controlled soldering iron. Lead solder can bathe the needle in a jacket of molten lead and temperature control is built into the soby Wiperman - Plastic Extruder Working Group
Delta robots can be as accurate as needed, and speeds are horrendous - about the fastest thing robotic on earth for pick and place when made with carbon fiber rods. I was at MACH2010 and saw a very fast one there and thats what inspired me to build a cheap duplicate from acrylic sheet. Precision is not bad in relative terms for this application because the fuse tends to be less accurate than theby Wiperman - Delta Machines
Design for my low cost Delta Thinking of fitting a small syringe needle as the nozzle instead of manufacturing metal parts. What da ya tink? That way I'm hoping the fuse will be <0.1mm and Delta bots are fast when it comes to weaving. And replacement nozzles will become easy to come by. The nozzle will be immersed in molten lead - the molten lead coming from a small light weight SMT temperatby Wiperman - Delta Machines
