Hey Guys, Have been working on making detachable flexible beds with spring steel. After testing in house for a month with satisfactory results, I would like to get feed back from the community. The sheets I have made are in two sizes for now, 220 X 220 mm and 300 X 300 mm. Currently would need to use binder clips to hold the spring steel down and can use painters tape or PEI Sheets on top. I am giving these at manufcaturing cost.
The sheet is powder coated in matt black to avoid rusting. The price is 300 Indian Rupees or 4.5 USD
The advantages that I have seen:
Prints come off super easy
Painters tape on the plate has not been replaced for over a month
No use of sharp Scrappers.
PM me on my number if interested : +91 8056138027
Currently working on high temperature magnets. If anyone interested in working with me on this do let me know.
Are you using it with a standard heated bed? How do you guarantee flatness when the sheet is flexible, which is not what you want or need. What machine are you testing it on?
@MidnightVisions I have tested it on wanhoa I3 which has a heated bed. The Spring steel usually maintains its flatness after being bent. I use binder clips to hold it in place for now, once a suitable magnetic sheet is developed, the magnet will ensure that it is held down evenly.
I have tested this for a month with quite a bit of bending. The parts snap of easily.
Spring steel is known to take a large amount of stress without deflectling.
Apart from testing it myself there is no other way I know off to guarantee flatness. I do not own a guage yet. A youtube video maybe ?
Let me know if there is any method that am missing out.
Just add high temperature magnets and u are good to go . I ordered a few spring steel pieces and the only problem I faced was that edges were bent when the idiot cut them .ther is no way that can be straighted !
@Kevin_Danger_Powers I wish I could, I cannot afford it now. Especially for the price am giving it at. Do you think Ebay or Amazon ship for low prices ?
@Hussain_Bhavnagarwal Spring steel, means it moves and vibrates under movement and clamping. It also it pushing the limits of the I3 heating element protection, which is a solder resist, which was never untended to stop short circuits, but only prevents shorts by the coating over the heating elements. I use a high heat glass to replace you spring steel, as it also prevents these issues.
I’d be interested in seeing how a Buildtak surface holds up to the bending.
Also, I’m betting you never actually have to bend it anywhere near as far as shown in the photo in actual use.
@MidnightVisions The binder clips have proven to be quite reliable so far. The sheet needs to be flat while putting on the clips, what I do is put the clips on one end and then press the plate down with one hand and put the clips on the other side. This will ensure the flatness.
@Christopher_Gaul There are many print types to consider to understand the problem. Let me explain.
Case 1: If the X and Y foot print is large, any build surface that is slightly flexible will work , as the corners of your print will pop off immediately and then getting the part off is much easier
Case 2: If you have a small X and Y foot print but the Z height is longer. In this case you can simply use your hand to remove the print as the moment force created will be enough to pop the part off.
Case 3: If your X , Y and Z foot print is small. This is the hardest case and this where I have struggled the most. The Build platform needs to be able to bend a considerable amount to get the print off.
I could probably take a video of the last case and demonstarte to you.
why “high temp magnetets” ? normal neodym magnets last a few hundred degres I use those on my oven (180C+) They ar chep and 4 to 8 on the side of the heater PCB should be enough
