But the ability to export your supports and then edit them in another app…that seems like it could be very valuable…albeit edge case as well. It was a pretty simple item iirc, something like a very simple soap dish with rounded corners.ĮDIT: all of that being said I can see how my case is completely an edge case and not a reason by itself to add this functionality. In the above scenario (which really did happen) we were forced to have me spend an hour or two learning 123Design and recreate the item to close enough to exact specs where no one noticed. form file, you really wish you could export to an STL because your boss wants you (me) to make one very small edit, then reimport and print. The guy who emails you your STLs is in another country (Mexico) and already home for the weekend. Since you are me, you don’t know how to use any 3D CAD program any more than you know how to transalte ancient Aramaic into Latin. It’s Friday afternoon and you have to get a print finished by Monday morning. TL DR : don’t use auto-orient if you want to really control the output of the printer.Curiosity is getting the better of me here… If you created the file in CAD, how is it you can’t export another Imagine you are me. This will replace the original model with the altered one while keeping the orientation.Īs for the issue 1, see my first paragraph. If you really want to use auto orient, then do it once, modify the STL with meshmixer without closing the file in preform (there is no link between preform and the source STL) based on Prefom’s proposal, then go back into preform, right click on the model -> replace -> select the STL again. If you’re loading the file in preform, hitting auto orient, go back to meshmixer to alter the model and then re-hit auto orient the result is almost certainly going to be different. If you’re adding drainage holes beforehand, you must already have an idea on how you want the print to be oriented, I suggest just manually orienting the part like you imagined it. Sound like you’re using the automatic orientation a lot, is there a reason to do so ? I think most user past absolute beginner will orient their prints manually, as its very unlikely the automatic orientation will get your part with supports where you want them. That being said, if you are able to do that, it would be excellent to be able to perform the hollow and drainage editing that I’m currently doing in Meshmixer entirely in Preform. form file cannot be edited in Meshmixer (at least to my knowledge) – it’d be handy to be able to add drainage holes to the print directly in Preform once the supports have been added. Overlapping the parts themselves may be less reliable, and as Rand圜ohen mentioned, I would generally advise joining the parts before importing them into PreForm. It seems like I cannot necessarily anticipate where Preform will determine the ‘best orientation’ for the model will be prior to printing, and the. I’m glad to hear your print turned out well Overlapping rafts can certainly be helpful, especially for smaller models - PreForm even has an option for doing so in the Layout tool. Suggestion: Make It Possible to Add Drainage Right in Preform (Maybe I’m doing something wrong?) Short of making the model loaded with holes, I’m stumped on the best way to tackle this. I’ll go back into Meshmixer and move my drainage holes, only to find that Preform will once again manage to flip the figure in a different way that the drainage holes are irrelevant and allow resin to pool inside the cups. (IE: Flipped so that they’re on the top of the figure being printed, for example.) STL file that I’ve hollowed out and added drainage to in Meshmixer, gets re-positioned in such a way that the drainage holes are badly positioned. Issue 2: Inconsistent Placement of Model Makes it Hard to Place Drainage HolesĪs I’ve been learning the ropes with my Form 2, I’ve noticed on more than one occasion that a. I’d rather have Preform try and give me alternative options (with appropriate warnings) that actually fit on the platform, as opposed to calculate supports for something that won’t. Suggestion: Allow Preform to Present an Alternative Layout that Fits This leads me to wonder why it’s so often the case that Preform seems to prefer an illegal orientation (which definitely cannot print) to a slightly-less-than-optimal one that can. I’m often able to orient them and add supports by hand in Preform – and successfully print. On larger models, I’ve noticed that the automatic orientation of files almost never seems to land the item wholly in the building zone of the platform. Issue 1: Large Files End Up Out of Bounds
