I’ve sent out models to be printed before but this is the first time I printed them in house on a formlabs resin printer

 

surface is very smooth compared to extruded printers

 

2 hours to print this part - 196 layers

For IG, you have to scroll to the right

Oh yeah - the tiny little arrow is almost invisible in the first pic. Thought it was part of the model... rofl2.gif

The dots under the pic tells you how many images there are to scroll thru

Of course it was designed for another kind of 3D printing.  You printed it upside down.  I don't know anything about resin printers but perhaps if it was turned over it would not have required any supports.  

 

I didn't see any other pics either except for the first screen shot.  Will now have to go back and see what I missed.

There's another arrow pointing the wrong way in the first pic, and the dots are on some talking head on the screen.

sla printer

 

it always requires supports no matter which way I print it.

 

the sla printer, it always prints a mass on a platter and from there the supports and from there the parts

 

the supports easily break off leaving minimal surface marks

 

the part is actually print up side down from what you see here

So I've printed about 12 of these IF by Dale and I had to beef up the part above - made the shaft thicker.

 

More importantly, the other part that holds the mirror (the socket that goes with this ball) needs to be made with something a bit flexible.  I used nylon which works great but formlabs has a flexible resin that should work.

 

The other parts that work well with flexible material are the diverging lens holder and the cube holder.  The diverging lens holder because you need to bend it open to get the lens in there.  The cube holder is the least critical to be flexible.

I don't know much about resin printers either but I know you can't print without supports.  They are mandatory.  Each layer is printed on the glass and you need to separate each layer from the glass so you can print the next layer and anyway the bottom layer needs to be discarded.  There's no such thing as a model that needs no support.  And if the model has a large flat area you want that tilted.  If you go from one layer that's tiny supports to a layer that has a huge surface area bad things can happen I think.  Quite different from FFF printers.

and the formlabs has a very nice finish...  you could print jewelry with it

not really, I rotate the part and get an estimated time to print, that's how I oriented this part...for time.

 

after the parts are printed and supports removed it has sit in a alcohol bath till its sticky free, and then cured in uv light.

I watched videos of the FormLabs printer thinking it might be an interesting addition to my shop. I do like the nice detail and finish it can make.  After watching and finding the material costs $150 per liter and other differences I decided it was not for me. It was out of my toy budget.  But it did intrigue me. 

 

Hope your prints go well and looking forward to seeing how it all comes together.  It was designed for slight flexible material so that it can snap together and also slide.  The actual design is over constrained according to precision mechanical engineers and without that flex will be sticky in motion I think.

$150 a liter is a lot better than my canon imageprograf 8 color plotter that costs $2500 every full set of colors... ouch. lol.gif

once clean and up cured the spa isn’t as brittle as pla stuff

This is all very nice, and I'm looking forward to seeing the final assembled product. 

However, I'm not entirely comfortable with the hidden political message in your your instagram pictures lol.gif lol.gif

If you check the bottom of this pic you'll see what I mean.

 

More seriously, how much does it cost to print the parts, I understand it's 150$/liter for the resin, I'm just trying to get an idea how many parts can be printed with this volume. Also, I guess the resin has a limited shelf life, so differently from filaments, one can't just store them in a drawer indefinitely....
