The correctly scanned areas will appear green, if you lose the tracking, the object will appear red. It is important that you move smoothly around the object. Move the scanner around the object (approximately 30 seconds for 360°). Click SCAN (green button on the left) to start scanning. Use 'Object' for small objects, 'Head' for medium and 'Body' for large objects. On the software interface you have the Scan Settings for the size of the object. You will see a green frame around the object that the starting position of the scan process. You should see the object as big as possible on your screen. Hold the scanner in 45° angle in front of the object. The environment light and the background should be homogeneous. See the instructions about the scanning process. Install and open the software for the Sense 3D scanner. It delivers tiny objects with a lot of details. Remove the support structure from the model carefully.ĬONCLUSION: For very small objects I recommend the Formlabs printer. I set 60 minutes at 60° C for the standard resin. Put the model into the Form Cure machine and set the correct parameter for the resin. Take the model out of the IPA basin and let it dry. You can use the Form Wasch alternatively. Put the model in a basin with Isopropyl Alcohol (IPA) > 90% concentration to remove the rest of the resin from the model for arround 10 minutes. Take care that you don't scratch the build plate. Remove the model from the build plate with a scraper. Take the build plate with the model out of the printer. Check that the resin tank and the build-plate are absolutely clean and the vent cap is open. Choose the mode to level the printer by rotating the feet under the printer with the round tolls. Send the model to the printer via Wi-Fi to the printer. Apply support structure and check that 'Preform' does not show red areas on the surface of the 3D model. If is necessary you have to rotate the object, so that the 3D model doesn’t stick to the plate. Size of the 3D model: diameter 25 mm, height 32 mm I choose the standard Material White Resin >Go to Next Start the Preform Software and choose the resin tank and cartridge (They get chipped when you insert them the first time). The resin is solidified and forms a single layer of the 3D volume. The laser draws a shape on to the resin vat. This process uses an ultraviolet laser on a vat of resin. I can change it in Grasshopper with the sliders. The distance between the spheres must be (for this size) bigger. You can see the result… It is very good, but some parts could not be printed. Size of the 3D model: diameter 64 mm, height 102 mm In Cura, I reduce the size for a test print and check the wall thickness. Once the spheres are being imported in Rhino I use the 'Boolean Difference' to subtract the spheres from the vase and export the 3D object as an STL file. Note: With the sliders you can change the size of the spheres, number of spheres in each row and the number of rows for the vase. The last step in Grasshopper is to 'Bake' the geometry (the spheres) for Rhino. The next basic steps are to move and rotate the rows with a sequence (Series) so that each row had a different angle. For this step I use the command 'Random'. In Grasshopper, it takes a while till I could array the spheres (command 'Array polar') and set different spheres sizes. I also add the base and the lid for the vase and generate a volume with the 'Boolean Union'. So I use the command 'Tube' and enter the wall thickness for the object. At first, I use the command 'Revolve' but it doesn’t work so well because I start “sketching” the form of the vase in the Front View of Rhino and set also the axis for the object.
