Description
The Stratasys is a commercial-grade 3D printer that was donated to the LHS by Imperial College London. It was repaired for a time, but is currently undergoing an extensive refurbishment to bring the electronics up to modern standards and properly convert it to non-vendor-specific feedstock.
DISPOSAL: Notice of Disposal applied by Tgreer on 11/12/2016. Scrapped & gutted sometime over xmas period by Hipster.
Pictures
Specification & documentation
- Usable Print Area: 270mm x 270mm x 300mm
- Top Print Speed: 20mm/sec (Yes its slow)
- Print Tolerance: 0.05mm in X and Y axes. Z axis is dependent on layer thickness
- Layer Thickness: 0.05mm to 0.2mm
- Supported Materials: ABS and PLA plastic filaments
- Usable Filament Sizes: standard 1.75mm
Training & instruction
Training IS REQUIRED and is being carried out voluntarily by the current maintainers, more info on the separate training page
Please do not use the printer if you have not been trained, even if you think you know how to use it.
Consumables
Only filament provided by the maintainers can be used in the Stratasys. This is to prevent any issues with poor quality filament. If we're running low on filament (or tape), ro recommended alternative providers, let them know (via the mailing list).
Filament options (3.0mm)
- ABS (lego brick plastic - prints at 190-230 DegC, requires heated bed at 100-110 DegC)
- PLA (biodegradable , based on food starch - prints at 185-190 DegC, optional heated bed, not hotter than 60 DegC)
- There are other 'specialist' filament, like wood effect, stone effect, nylon (can be coloured by clothes dye), etc

After providing spare hands to tgreer in trying to get the new controller wired in for the open-day, I noticed both motor connector plastics are extremely perished. Sockets and plugs. The Y-axis (?) stepper connector has previously been bodged. Pins no longer make good electrical contact with bodged SIL connector. This is both due to bent pins that have apparently been forced, but also the SIL socket terminals sliding freely in their plastics. Pins on stepper are also able to move into the motor body when pressed! Attempting to press another connector onto them will likely push them all the way into the motor housing, rendering the motor useless. As the motor pins still pass continuity tests, this severely damaged connection seems the likely reason for the motor skipping phases. My recomendation is that flying leads are soldered directly to the damaged pins and connected to a seperate connector that can be fixed to the chassis. Possibly a DB9. Replacing the steppers entirely is a possibility, but will be tricky due to the capstan-drive. Removing the stepper will probably mean re-winding and re-tensioning the system.
The capstan drums seem at risk already however, as the (nylon?) coating on the steel cable is severely deteriorated, cracked and flaking off. Once the coating fails sufficiently to expose the cable, the cable will begin to eat into the surface of the aluminium capstan drums, ruining them. The drums are not likely to be easily replaced, the motors and cable are.
While the cable is fine for testing use, if the Statasys is going to be used frequently, new cable should be sourced as a priority.

The milled parts should arrive any day now and, once installed, we should be ready for a first test print.
As far as I am concerned, based on the investment by members, a successful print of any description, using both extruders or not, is proof of working. Having experimented with Dual Extruders, the configuration too complicated to include this by the (self imposed) deadline.
Thanks Ian

Currently the Stratasys is moving and the hot-ends/extruders are working. We are waiting for the aluminium to mount the hot-ends in.
Once this is completed, it shouldn't take much longer to have this completed and working.
However, as I mentioned on IRC, if we cannot have a completed print by Christmas, I think this project should be marked as 'not completable' (if there is such as word) and we call it a day...
Thanks Ian

To the mailing list:
Hey all.
Right, finally got time today to do a thorough check-up on the stratasys. As I have rpreviously said, all internal mechanics (including the steppers) are in full working order, especially as I performed a strip and clean to it pre-move.
After a quick talk with Ian on Wednesday, I have traced all the cables and found all the documentation for the parts, ferrous detecting end-stops, x-y controller pin outs, steppers etc. I have removed the old and power hungry heaters and flourescent lights.
I have paird the stepper cables and made ready for the 4-wire board. Also gave another clean
Basically it is ready to be connected to control board and ready to run.
All we need now are to nice tourqey nema17 steppers, 2 j-hotends (ian has offered to source and will start pledge, less than £100). Once these have turned up and I've cad modeled them, i will design a nice clean and easily accesable mount for them in the existing hot end housing (also been cleaned).
Charles will need to add a ACNode and it'll be up and running as a tool for the space. But like the laser cutter and charles, I will be its main care-taker/daddy lol.
Hope this has cleared up any concerns or apprensions about having a fully working, accurate, industrial 3D printer in the space to be used by people with training.

Hipster
