Solargraph from a one-year exposure on film. Is there a resin printer in your future? If so, you might want to look over ’s guide to the pros and cons of SLA compared to FDM printers.Ĭontinue reading “Silky Smooth Resin Printer Timelapses Thanks To Machine Vision” → Posted in 3d Printer hacks Tagged Circle-Hough, Elegoo, intervalometer, machine vision, MSLA, opencv, RIFE, sla, time-lapse Alex kindly provides his code if you want to give this a whack it’s almost worth buying a resin printer just to try. The details of that technique alone were worth the price of admission, and the results are spectacular. To smooth things out further, also used frame interpolation to fill in the gaps where the build platform appears to jump between frames using real-time intermediate flow estimation, or RIFE. A Python program then sorts the frames, so it looks like the resin print is being pulled out of the vat in one smooth pull. The LED acts as a fiducial that OpenCV can easily find in each frame, one that indicates the Z-axis position of the stage when the photo was taken. The advantage of his method is that it’ll work with any camera and requires no hardware other than a little LED throwie attached to the build platform of the printer. Or are they? found a way to make gorgeous time-lapse videos of resin printers that have to be seen to be believed. That’s easy enough to do on FDM printers, but resin printers are another thing altogether.
Trouble is they tend to look choppy and unpleasant unless the exposures are synchronized to the motion of the gantry. The fascination of watching a 3D printer go through its paces does tend to wear off after you spent a few hours doing it, in which case those cool time-lapse videos come in handy.
