Week 6

Feb 20. 3D Scanning and Printing



Group Assignment

Test design rules for the 3D printer to be used. We tested three an ultimaker, a rostock and a syndoh to define which one to used in each assignment.

3D Test model

Choose a 3D Test Model to print.

SW Ultimaker Test

We reviewed the piece to be printed in the software prior to printing.

Printing 1st Test

Printing started.

Rostock/h4>

Great for angles.

Syndoh

Great for long defined vertical lines.

Ultimaker

Best definition, not great at angles or vertical lines.

Top View

Syndoh appears the best from the top with definition of vertical lines.

Bottom View

The best quality inside was the Rostock, angles are great with this printer.

Side View

The best overall is the syndoh.

Instructions

  1. Look for a test model and download from Internet
  2. Guarantee is a small enough piece that it will print within a small am ouont of time (took 4 hours each)
  3. Open in the program for 3D printing
  4. The parameters used for all printers were. layer height 0.15 and Fill 25%
  5. Open in 3D printer
  6. Press start
  7. Wait until ready
  8. Eliminate any excess material from the piece
  9. Repeat with Rostock and Syndoh
  10. Compare pieces
  11. I decided to print all of my pieces in the ultimaker despite Syndoh being the best quality overall becauase I did not need to print any angles or vertical lines.


Individual Assignment

3D scan an object with different techniques and optionally print it. I used three different techniques, laser arm scan (Romer), white lighting scanning (Shining 3D) and photometrics (Qlone for iPhone).

Romer

Scanner used to test the scan by points technique.

Scanning

Scanning with this technique is by far the most difficult one, you need to cover all surfaces several times.

Scan Points

Point map created by the scanner software.

Final Result (arm)

The final result from the romer was imported into GeoMagic and this was my end result (not proud).

Qlone Scan

Software for iPhone that uses telemetrics.

Final Video (Qlone)

By far the best end product. I decided not to print this pieces because sending it .stl costs, and I wanted to try another technique.

Scanner

Piece to be scanned on scanning table

Scanning

By far the easiest technique yet for me.

Final Mesh

The mesh is created effortlessly and just touched up in Mesh Mixer

Printed piece

The lightining scanner piece was printed.

Side by Side

Side by side comparison is pretty good, the texture was recognized from the painting in the original piece.

Mirror

Mirror images, the original piece and the new printed one.

Instructions Romer

  1. Start arm and connect to the computer
  2. Start software and open scanning mode
  3. Start moving the laser scan all around the piece
  4. Continuosly check that the piece is being formed in the computer software
  5. Continue scanning until th efigure is recognizable
  6. Save the final result as a txt with coordenates
  7. Open txt fil in GeoMagic
  8. Close mesh as good as possible
  9. Define if you are going to priint the file, if yes export to .stl (I did not print this one)

Instructions Qlone

  1. Install Qlone onyour phone or tablet
  2. Print mat to define scanning region
  3. Put your piece in the center of mat
  4. Start app
  5. Follow your phone trying to get rid of the dome that the app creates over your piece
  6. Once the dome is transparent your piece is finished
  7. The end result is gorgeous, exactly like the original
  8. Export to as many formats as you want (and/or want to pay for)
  9. You can even play with your model with Augmented Reality
  10. I decided not print this model although it was the best by far, because creating an stl file came with a price

Instructions Lighting Scanner

  1. Install the scanner and connect to your computer
  2. Open the scanning software
  3. Callibrate, if the scanner is not callibrated it won't work (believe me we tried)
  4. Set your piece in the middle of the rotating plate
  5. Set the scanner to identify your piece, this means selecting the kind of color it will receive (light or dark pieces need differente parameters)
  6. Select the number of loops it will make, 25 loops in this case
  7. Press play and start scanning
  8. Don't move your piece while scanning, be patient
  9. After the scanning is finished put your piece on the side and start scanning again
  10. Don't move your piece
  11. After both scans are finished merge both mesh
  12. Save your project
  13. Open in Mesh mixer to clean up a bit
  14. Export to stl to be printed
  15. This was the easiest way to scan

Instructions Printing

  1. Open in the program for 3D printing
  2. The parameters used for all printers were. layer height 0.15 and Fill 25%
  3. Open in 3D printer
  4. Press start
  5. Wait until ready
  6. Eliminate any excess material from the piece
  7. Compare to original piece


Individual Assignment

Design and 3D print an object (small, few sqaure centimeters, limited by printer time), that could not be made substractively.

First Attempt

Model without extruding the square.

Final Model

Model with square's faces extruded.

Original model in printer

Model ready to print, it was to big for comfort.

Scaled model in printer

Scale to 50% of original model

Picture of Rattle

Printed piece.

It Rattles!

Piece being demonstrated.

Instructions

  1. Open Fusion 360
  2. Go to the sculpting tools
  3. Create a square and start subdividng each face
  4. Eliminate excess faces to create a whole in each side
  5. Create a sphere and insert within the square
  6. Extrude the square to 5 mm so it will have depth and can be printed (my first attemp was not extruded and couldn't be printed)
  7. Export to stl for 3D printing
  8. Open in 3d printer software, set parameteres, fill 25%, minimum support
  9. Print and wait for final result
  10. Eliminate support and excess material from piece
  11. Play with it, it rattles!
