Topic: SD3 build platform arm replacement

Hi all,
my SD3 arrived the other day and opened it to find that the build platform was broken off. I have contacted support and such to get a new part delivered, but in the mean time i am trying to make a CAD of the arm so i can print one off either in the future or to print one off at my place of work(I have access to a stratasys fortus 900 printer and Ultem 9085 material). I am having trouble finding the correct dimensions of the arm because of the condition and was wondering if anyone has an existing CAD or knowledge of the dimensions that they would not mind sharing with me.

-Thanks

Re: SD3 build platform arm replacement

Hi Sickma, I'm just now taking measurments to draw one up and have it machined. I'll post what I can figure out. I didnt want to remove my platform again to measure it, so it would be great if you could provide any measurments as well so we could compare it to improve accuracy.  I'm hoping to have mine machined in alumunium so my design might change a little bit.  I'm not sure about how ridged a printed plastic piece will be over time.

Re: SD3 build platform arm replacement

So here is a basic 3d model of the SD3 platform drawn in AutoCAD and saved as a 2010 .dwg file and as an .stl.  I did not compensate for the linear bearings or anything else yet.  If anyone can double check these dimensions that would be great.

I'd honestly just wait for the replacement.  It seems to be working fine for most others in use, you just seemed to have some back luck during shipment.  I haven't heard of it before yours.   From this point on anytime you try to talk to support they're going to point to your modified platform because that's something out of their control.

Re: SD3 build platform arm replacement

Personaly I have already repaired mine as I didnt want to add another month to my already 6 month wait. I think the wood piece could be fine for the smaller cantaliever of the SD2, but I think over time it could be a week point for the SD3.  I also plan on transporting mine between home and work, and don't want to have to worry about it.  If the frame can support an adult, I dont see why the inside can't be a little more robust.

I just noticed a couple of stray lines in my drawing, so if anyone plans on using it, just keep that in mind.

Re: SD3 build platform arm replacement

the 6x6 aluminum weighs about .45lbs assuming 1/8" thickness, the 8x8 is .80lbs  You're free to do what you want but I don't think the added mass is going to change anything.  I think UPS or USPS tossed your printer down a flight of stairs and the filament cracked the wood.

Re: SD3 build platform arm replacement

Hey toolbox, your measurements are good to what i can see. The only measurement i can't be sure about is the y-axis length of the arm.
Also make sure you make room in the back for the Z-axis motor.
