Very interesting as long as the water is disposed of properly. Thanks for the tip…I’ll experiment with this!

These were printed on the Form 2, which is a little more forgiving with supports and orientation. This is also a demonstration of how this method works against very difficult to remove parts. We do still recommend printing at an angle and with supports.

Maybe I will be little off-topic, sorry for that. Anyway, could you, please, elaborate on the reason, why/how the new wiper system helps extending the life of the resin tank?
No worries! The wiper system ensures that the silicone in the bottom of the tank is always clear of debris. If there is cured resin stuck to the bottom…it can degrade the the tank faster. Additionally…it mixes the resin and oxygenates the silicone after each layer. The Form 1+ resin tank must be replaced every 1.5 - 2 liters of resin. During testing, we’ve seen the Form 2 resin tanks last around 3 liters of resin before replacement is required.

Great tip, thanks!
How about some tips on when it is safe to not use auto orientation prior to support creation. I had some small airplane props, 1.5" tip to tip the other day. Auto orientation with auto supports and manually edited supports kept giving me red areas on one blade tim. By just keeping the flat and generating supports, no red.
Boom, added to the list. Thanks for the suggestion!
This may already be out there, but and explanation of why the software always angles parts during orientation would be helpful. I often have customers ask how big is your build volume on the Form I tell them but also have to tell them we can’t build that big because the software orients parts at an angle. Sometimes they ask why and right now I have to say, "I don’t know, it probably has to do with better quality during printing.
My questions to you is what is the software trying to optimize for when it angles parts? A video show and tell would be nice.
I’ll definitely try to get a video together that talk about this a little bit. Quoting our support material:
“Flat surfaces with support structures print much more successfully at an angle of at least 10–20º. You will notice that if you use the automatic orientation in PreForm by highlighting your part and clicking “Orient Selected” it will usually position your piece at an angle. After each layer, the printer performs a “peel” process, which literally peels the layer off the PDMS surface of the resin tank. The forces involved can distort the extremely thin layer of a flat surface mounted on support structures. If a planar surface is oriented at an angle to the build platform, there is only a little overhang for each new layer. Furthermore, many thin-walled parts present significantly less area in any slice when printed at an angle.”

Hi I’m curious to see how you will use the support in F2 I do not like Formlabs’ support because they are too thick for jewelry.

Hi Jory,
Did you ever make a video about printing without supports? Could you please link to it?
Thanks!
