...just todayNeed to 3D print some widget for a project... Draw it up and... buy a cheap 3D printer and have some fun with it.
I got myself a big roll of white paper (4 foot wide). Having hardwood floors, I am just going tape a piece down that is the right length. I will be able to draw a lot of the parts to 1:1 scale. Technically, I could draw even the wing spars full size if I wanted to do so.Free-hand drawings are more than adequate. If you don’t want to use a drafting table, get some cross-ruled drawing paper, either in 1/10” or 1/8”, whichever you think in.
Cheat trick: figure out how big you need the airfoil to be for each rib. Take a graphic of the foil in question and blow it up to the correct size. Go to Office Depot or something and have it printed off. You can then draw on that.The airfoil deserved a reasonably accurate rendition, assuming that you are not planning to have advanced sailplane-like performance. That is easily accomplished with patience and persistence, and a French curve.
I'd have laid it flat... If supports are pretty dialed in it's 30 seconds of Cleanup and less likely to snap clean off in the hole. Threads like that print nice but usually aren't super strong......just today.
Looks like the interface to a Prusa i3 mk3. Mine has been printing pretty much nonstop for the last 2 months.Which printer are you building? (I'm guessing doesn't look like MPCNC but does look a bit like the railcore)
Ah, interesting - I was hoping you'd say railcore. I've got all the parts except that unobtainable 1515 extrusion for it. You might want to eyeball up it's Z though, it's way better than the cantilevered designs.
Thanks for the heads up!Looks like the interface to a Prusa i3 mk3. Mine has been printing pretty much nonstop for the last 2 months.
After upgrading some electronics and getting timelapse capability a couple days ago:
BTW in Solidworks (and most likely Fusion 360), you can input coordinate curves...so you can pretty much reproduce any airfoil that a DAT file, which is the same airfoil coordinate files used by XFLR5, Xfoil, Digital DATCOM, etc. So you can pretty much turn any airfoil found here into an accurate and scalable profile: https://m-selig.ae.illinois.edu/ads/coord_database.html
.STP and .IGS files are basic model types that just about all CAD systems can use. I hope someone has a better method than this, but... you could save all your SW files as .stp or .igs and bring them up in your new CAD system.-- File compatibility with the SolidWorks files you've made
Fusion 360 and SW are very similar. I don't think the transition between those two would be a big deal.-- Operational similarity to SolidWorks (i.e. how much do I have to re-learn?)
As usual there is no one size fits all answer. In general there are ways to convert SW native files to other formats and retain the parametric qualities. I've, in the past managed to strip off the student watermark by exporting to Alibre and then back to SW via *.IGS files.Si
There's not much point in spending a lot of time on the details of these, but in >general<, is it practical for a SolidWorks user to convert his/her files to be used on any of these other products, or does everything need to be recreated?
If you export from SW as step or iges, the models will just be dumb hunks of stuff..STP and .IGS files are basic model types that just about all CAD systems can use.
