3D Design Basics with inkscape and tinkercad (workshops #3)
- 1. 3D Workshop #2 - 3D Design Basics with Inkscape, and Tinkercad Michelle Folkman
- 2. Do You 3D?
- 3. Objectives --> --> B&W Image Inkscape Tinkercad
- 4. 3D Concepts bitmaps / raster images are made of pixels 3D objects are made of vectors (points) and paths
- 5. In Inkscape Steps: ● In Inkscape → File→Import ● Make sure image is selected → Path → Trace Bitmap ● Use brightness cutoff→ colors = 2 ● File → Save As → Plain SVG ● For text → Use Text tool → ● Save as a .png ● Import the .png file and follow steps above
- 6. In Tinkercad ● Import → File → Choose File ● Choose .SVG ● Click on Download for 3D printing - save .STL file ● Or - Click Order a 3D print and use an online service
- 7. In Makerbot ● Settings - turn on rafts and supports ● Add file → May have to adjust scale and rotation ● Click on Download for 3D printing - save .STL file ● Or - Click Order a 3D print and use an online service

- Hi everyone and welcome to the workshop My name is Michelle Folkman and I am here today to do another workshop on 3D design and printing. We had some difficulties with Blackboard, last week, we had to make a tutorial rather than a live recording, but here we are this week If you want to see last weeks recording it is at http://library.uncg.edu/research/tutorials/3dworkshopone.mp4
- Let me tell you about myself. I have been 3D modeling for about 20 years, which is great but I recently found hat 3D modeling for printing is different than the 3D modeling I have been used to – so I am learning right along with you! What you see here is a 3D model of a hand, just a cool thing I found
- So what we are going to do today is start with a black and white image – maybe like the sketch on the left, or really any black and white image such as a logo, or text and using a free piece of software called Inkscape - Inkscape is a lot like Illustrator but free prepare the image to be turned into a 3D model. Then in Tinkercad, which we introduced last week, check out the recording if you get a chance we will make a simple 3D model suitable for printing. I’m going to do two examples, one using an image, one using text Finally at the end we will step through taking that model into the 3D printer software and preparing it for print. Oh and by the way, we will build in some time for questions at the end. ANd this is being recorded and it and the slides will be available
- Before we get started, like I did last week, let me first introduce you to some terms –raster, bitmap, vector and object. (Edges, faces, points (vertex)) By now, many people are used to working with pixels – little block of color. That is known as a raster or bitmap image. Zoom in you see blurry blocks 3D models are different – they are virtual 3D objects, that “live” in 3D space 3D objects are made up of vectors and the paths that connect them ( a vector may also be called a point) To make a model, we must start by convert a raster or bitmap image into a vector object – we vectorize it – and turn it into points and paths
- Im going to demonstrate a couple of different images to 3D, and text to 3D. In Inkscape File→ Import Black on white background works best – make sure object is selected --> Trace Bitmap à Brightness cutoff – colors 2 Menu does not automatically dissapear - close it Show how it is a little weird – use point tool – to show – use Selection tool erase bitmap demo import b&w drawing and save demo how to do text and save Inkscape – do text (Calligraffiti 144) Show trace bitmap doesn’t work Save as .png Delete Import.png file Trace bitmap File→ Save As--> Plain SVG
- Go to Tinkercad Review capabilities – how to get around, zoom, grid snap, etc. Import into Tinkercad – add a box, group Mention that the steps to do this are on the slides
- Go to Makerbot software Review capabilities, rotation scale etc Settings - explain rafters and supports - get a more reliable product Add file - adjust scale and rotation Export print file Print preview Show layers Show travel moves Point out Print Time an weight of filament Exports – saves it as an .STL - sterolithography The slides with these steps and the recording are at:
