Talk:D3D Requirements
Tobbens quick first comments:
- 1 day
This is then the major hurdle to overcome. It is clear and measurable, and we do it for economical reasons, so I like it.
- Auto bed level
Increases usability tremendously. Off the shelf solutions exist.
- OSHWA compliant, Respects Your Freedom certified
OSHWA compliant is no probs. RYF-certification might require us to apply and might take some time? Would help win the confidence of like-minded potential contributors.
- $500 in parts for single head
That's plenty. We will trade "cheapness" for "reliability" and "ease of build", so I think 500 a good limit.
- Wireless to allow for freeing up computer
Freeing up computer is best done like this: upload gcode to SD card. Start SD print. Wirelessness only frees user from USB/internet cable-hassle at start of print. Requiring SD capability would be reasonable. There are off the shelf solutions available both for wireless and SD.
- Rubber print capable, without head exchange (critical for OSE gaskets, rubber washers and o-rings in low and high pressure hydraulics and pneumatics)
This would mean a no-Bowden filament feed. I agree.
- Multiple print head addable, up to 4 for practical considerations
- Meets or exceeds reliability of Lulzbot
- Addable clear enclosure
- XY-fixed build platform
- Unheated build platform
- Self-harvesting for mass production part capacity
- Future: works.with irregular-dimension filament?
- Functional Logic and design rationale is fully documented
- conductive metal print capable for Cordless Tool Construction Set
