My 3D Printing Adventure

View image on Twitter

Awesome! Got around 2 hours of 3D lecture, hands-on and printing session – all for free!

I was actually scheduled to attend the lecture a week later but I took my chances anyway, hoping few attendees will miss their schedule. I really thought it would be a full house as these are free sessions. I was a bit surprised nobody’s still around at scheduled time so I chatted with the teacher and asked if I could attend. I was allowed so I sit right in the front seat. There are only like total 6 of us, one is not even attending, just sitting there to use the computer for his own project. And the venue can accommodate 12 people.

Lecture went well, actually just an hour was spent on it. The other hour was spent on printing. That small piece of around 1.4×5.4×0.4 cm took around an hour from preparations to actual printout pictured here. Preparations included the following:

  • Loading the filament
  • Warming up the printer
  • Downloading the 3D file
  • Processing the 3D file to ensure correct scale
  • Copying the processed 3D file to the USB stick
  • Putting the USB stick to the 3D printer

We were actually not aware that we can print our mini project for free but our teacher mentioned it before we finish our lecture. In the session’s flyer, it was stated that we have to bring our own USB stick. I did not bring any but our teacher volunteered to lend us, so I got excited and finished in a hurry a keychain project suggested to us.

In the first few minutes of printing, it was confusing for me because it did not look like the object I have drawn. Turned out, it have to first print a base so the rest of the object would be printed on it, improving printing accuracy by doing it on a more stable surface. I almost cancelled the printing process but I decided to just let it take its turtle pace. I spent time instead reminiscing of CAD plotting decades ago. Sure is much more interesting watching 3D printing compared to plotting in tracing paper.

After more than 30 minutes of actual printing, it was done. I’m still confused because the printed object is way more than what I’ve drawn. Then our teacher brought out a spatula, scraped the 3D stuff out of the printer. After being removed from the printer, it was like peeling an orange, removing the extra objects. Finally, the 3D object I’ve drawn an hour ago was handed over to me :)

As for technicalities, here are what we used in the session:

  • A computer with internet connection
  • TinkerCAD (A free online CAD software :)
  • User’s TinkerCAD account
  • Makerbot Replicator 5th Gen 3D Printer
  • Filament (blue)
  • USB stick (bring your own)

Oh by the way, we did it at Chinguacousy Library near Bramalea City Centre, just beside the Bramalea Bus terminal.

About 3D printing technology, it sure is exciting with much more advancements to come. My prediction is, just like paper printing which started from dot matrix using ribbon, to ink to laser printer – I look forward to 3D printing using cartridges that prints in color. That would be an exciting development to watch. Ultimately, printings would develop into holographic projections and replicators ala Star Trek, which I hope to see in my lifetime.

Godspeed!

Windows 10 Creators Update – My Smoothest Upgrade To-Date

W10CUa

Just like other updates, can’t shake my anxiety before going through this update. I kind of expecting an alert or email from Microsoft for the upgrade but didn’t receive any so I just searched for it. Found it and still unsure how it’ll go but proceeded with the upgrade anyway. And I’m glad to have gone through it as it turned out to be my smoothest upgrade ever :)

As I recall, I simply searched for “Windows 10 Creators Upgrade”, then a webpage appeared where I clicked the link to Microsoft software download website. As I usually do, I downloaded the update file and run it though my local explorer. Download was quick but the upgrade process after that took more than an hour. Other than having to re-login after the restart, all else were automatic.

After the upgrade, I took sometime checking “What’s New?”. It showed me that IE or MS Edge is now the faster browser. Tested it and looks like it. However, I still have to go back to Google Chrome to be able to stream to my TV as I only have Chromecast. Would have been nice if MS Edge almost makes available streaming to Chromecast.

Quite impressed with new features:

  • fast and convenient browser where you can now more easily jump through tabs
  • Paint 3D already installed, thought I have to install this app separately; plan to soon do few 3D sketched which I hope could be 3D printed just as easily; Tried Paint 3D, drawn this:
    Test3D
    Yet have to figure out how to show the 3D file.
  • Windows Ink
    Where you can easily annotate desktop or browser, neat! I believe this’ll come in handy in software development project.

All for now, will update this post on future learnings…
