Topic: What would your ultimate 3d printer have?
I scored a pallet of heavy duty extruded aluminum+connecting hardware, industrial ways, and bearings (all nearly brand new) at a local auction and decided they would be the start of an "ultimate" FDM 3d printer. Will be way over-kill as I estimate the value of these parts to be north of $8000 (which I got for pennies on the dollar) but over-kill is how I like my tools so before making the first cut, I decided to give some thought as to what, exactly, this monster should look like and to solicit opinions from the experienced folks here. Here's my initial thoughts:
cartesian (build plate for Z, X&Y on extruder - just like my SD4, just better)
heavy duty, modular frame (large extruded aluminum with T-slots)
enclosed in plexiglass
easily modifiable (modifiable for use for engraving, laser cutting, plasma cutting, milling, DNA sequencing, whatever).
At least four extruders (thinking of trying the diamond hot end kick-starter for three of the extruders and having at least one extra auxiliary nozzle for filler/flex/support specialty filament)
Auto bed levelling
large, rigid, rectangular build platform (XYZ=36x18x36). My extruded aluminum has a 90mmX90mm cross section so I think it will be rigid enough. Will never use the full volume due to time constraints - but want flexibility to print long parts, or many parts before clearing the bed
quick heating bed (yes, I will need a huge PSU). Thinking I could experiment with fluids for quick heat up and cool down.
high-end, expandable controller board (suggestions, anyone?)
probably both Bowden and local extruder motors (use the Bowden for the diamond hot end and local for the extra)
Anything else I should consider?
