Because we all 3D print things like this perfectly the first time…

Or maybe more like this…

How can we get prints more like this?

But many problems are rooted in design. So let’s learn about Design for 3D Printing @you3dit #sketch2solid

What design software do I use?

The basic Design for 3D Printing Rules 1.

2. 3. 4. 5. 6. 7. 8.

Have an answer for “Why am I 3D printing this part?” Start small Have at least one flat surface Avoid large-aspect-ratio parts and features Use 3D Printer Friendly Angles Avoid sharp corners Design with part orientation in mind Conserve plastic, conserve time @you3dit #sketch2solid

1. Why are you 3D printing this part? 1. 2. 3. 4. 5. 6.

Highly customized? Highly complex? Easy access to the tool? Curiosity? Material preference? Ease of use?

2. Start Small 1.

Large prints take a LOT of time to print 2. Larger prints are more prone to errors 3. Large prints are more costly if there’s a failure

3. Have at least one flat surface 1.

Have at least one flat surface part can rest on

4. Avoid high-aspectratio parts 1. They tend to warp 2. Warping is caused by thermal gradients and thermal contraction 3. Thermal contraction has the largest impact on highaspect-ratio parts

@you3dit #sketch2solid

4. Avoid high-aspect-ratio parts 1. They tend to warp 2. Warping is caused by differential thermal expansion 3. Has the largest impact on highaspect-ratio parts 4. Warping not only distorts final print, but can cause print failure

@you3dit #sketch2solid

5. Use 3D Printer Friendly Angles 1. Avoid sharp corners 2. Avoid angles larger than 60 degrees from vertical 3. Fillets and chamfers are your friends 4. Sharp corners also jolt hardware in the 3D printer @you3dit #sketch2solid
