This week I started from to use the Ciclop Scanner. It works with two laser and one webcam. For first thing I calibrated the scanner and prepared the set, with three lights, for to make soft shadows and to make correct lighting. Also I was careful to don’t focus light directly on the object, but I did reflect light on the table or I made a soft light with a white paper placed in front of the light.

After that I set the scanning to max resolution. The scanning lasted about 15 minutes.

When I opened the file there was a points cloud, there wasn’t any mesh.

So, I had to create a mesh from cloud points, with Mesh Labs software. After that I imported the model in Meshmixer, I sculpted it for fixing.

Kinect Scanner

The Kinect scanner, in my opinion, is better than laser scanner, which it’s simpler because the software make a mesh, not cloud points. But the quality is low. With my classmate we scanned each other, but the particulars of our face were bad, and in the mesh there were more error.

Anyway, we prepared the set, one chair in the middle room, without obstacles in a radius of one meter and we set the software. I took the file and fixed with Meshmixer and created the STL file.

Finally I wanted to test the Ultimaker 2 Printer, for to print my model. I drew quickly my logo in 3D with Rhino and I created one base for support. I used Cura for the slicing.

123D Catch

In my opinion this is a very potential software. I tried this with some simple photos took with my phone. After some testing, I used my reflex camera and the desktop version of the software for to scan one little cactus. I understood that the software needs of a reference on the floor, under the object, like a newspaper. The software delete automatically the environment thanks to the depth of picture, so I took the photos near the object and I focused the details that interest me, like the potting soil and cactus thorns. I turned around the plant two times, with two different heights, after that I took photos with zoom, for details. I took seventy pictures, because the software can’t upload over this number of pictures.

With Meshmixer I cut the ground plane and the mesh that were among the leaves. With Fusion 360 I made the vase. I was amazed how the software created the particulars of the plant, like the cactus thorns.

I decided to lunch the print with SLA printer, for to test this technologies, but also for the thin particular of the plant. I set the file very simply with the wizard option. I changed only the position and the supports.

Set the printer software for to send the printing.

Start to printing.

After about 2 hour the printer finished and I could take the model and put it inside the alcool container, for to clean it from the resin. But I think that I was wrong something, because the vase was deformed and the surface was some sticky. Maybe because I was wrong to remove the supports and I took the model inside the alcool for too much time.

Finally I left to dry it and cut the support.

Meantime I enjoyed to try cloud rendering of Fusion 360. This is an amazing and fast tool for to take some rendering in high resolution in short time and with low level computer.

3D Printing

Testing 3D printers

For the printing test, I used the Delta 2030 and Zortrax printer. I did the same printing test, from Make’s file on Thingiverse. Because I could see the difference of machines and materials (PLA Vs ABS). I saw that for something it was one machine and for another things was better the other machine.

I saw the quality of layers is better with ABS, but the writing is better with PLA. Despite everything the Euro coin couldn't to be place in the both holes.

I measured the diameter on 3D file, the diameter of Euro coin, and after both 3D models. I saw a little difference:

  • 3D File= 23,25 mm
  • Euro coin= 23,20 mm
  • ABS model= 22,70 mm
  • PLA model= 22,77 mm
  • Testing Euro coin in Zortrax's print.

    Also I printed another files for testing the angle of printing without supports, bridge printing without support, and the spikes for testing the retraction without filaments like spider web. My considerations are that for the first of the angles is better the ABS, with Zortrax, instead for to the bridge test, for me is better the PLA with Delta, same thing about spikes test, because the ABS model was found very fragile, in fact one spike broke.

    Voronoi Lamp (final project’s draft)

    Link to 2° week, sketch, modelling and rendering.

    For the assignment of this week, to print something of possible only with 3D printing technology, I decided to print my draft of final project. It’s a voronoi structure, which I drew with T-spline for Rhinocheros. I printed this object in 1:2 scale (about 150 mm of width). I set gcode with Cura, for Delta 2030 printer. I think that I was wrong, because I printed this in horizontal. In this way Cura had generated many supports and the quality of print is bad, because the layers are parallel to the long side of object. For me it would be better print the object in vertical. Anyway, after the printing, I smoothed the model with Dremel and sand paper.
