Here is a fender I made for my Onewheel, with the logo Velocity Painted. It is ESUN PETG, printed at 260C. The main shell is thin enough that it printed as a single perimeter. I set the infill for that section to 0, leaving a small gap between the top and bottom faces. The velocity painting is set to slow down over the logo so it is thicker, creating a bit of a relief. Because there is a gap between the surfaces, there is more play of light against the edges of the logo, and bouncing around between the inner and outer surfaces. Earlier versions were sliced with perimeter infill in the middle, and it didn't have that interesting shimmer. The print is fairly weak since it is hollow in the center section, so I reinforced it with fiberglass on the underside.

I'm going to do another one soon with a speed up over the logo rather than slow down, and see how that looks.

I have a question about +Simplify3D and extrusion widths – I thought I understood, but clearly I don't.

I was looking at +SPANNERHANDS 3D Printing's Prusa i3 S3D settings and he has his extrusion width set to 0.43 (rather than my current setting of Auto (0.48?)).

So, I thought I'd try a print with the extrusion width set to 0.43 – nothing else different. And it under-extruded, very obviously. Some small top surfaces have slight gaps, multiple perimeters sit next to each other but don't quite touch, and – the most obvious – the brim consisted of separate rings. not quite touching (so useless as a brim).

No pictures as the part is copyright (for a client -- I've reprinted with my usual settings for him).

Now, +SPANNERHANDS 3D Printing has an extrusion multiplier much higher than mine (1, whereas mine is 0.95), and upping my extrusion multiplier may well fix things, but:

For the brim (for example), surely S3D is supposed to place the concentric rings of the brim according to the extrusion width? And surely that's the case for the rest of the print as well? Surely changing the perimeter width shouldn't mean we have to tweak the flow rate?

Remember, all I have changed between the (absolutely fine) print with my default settings and the print that looks obviously under-nourished, is the extrusion width, nothing else.

Can anyone shed any light on this? I'd love to know what's going on here as I thought I understood, but clearly I don't.

My first use of Polysmooth. Transparent Polysmooth before and after Polyshing. 0.15mm layer height on an Original Prusa i3 MK2S. 40min Polyshing with 99.9% IPA. Result!

Possibly even a game changer?

Finally found a good way to use the +Faberdashery Ltd. 100m hanks, and it involves cake.

Take one old spool (+rigid. ink black ASA :), an unopened box of +Polymaker Polysmooth, a Lazy Susan and a largish tin of cake. Also add the original +Josef Prusa spool holder, as the filament threads though a hole in that before heading for the extruder.

Works like a charm. For an even slicker version that doesn't need the Polysmooth, simply add more cake.

Velocity Painting – have a go

I've just released the STL, image, instructions and processed Prusa i3 MK2 GCODE for my Vase With Climbing rose

There's an app available so why not have a go yourself?

What do you buy your dairy-intolerant #3Dprinting enthusiast Dad for Easter? A dark-chocolate low-poly Easter Bunny! Thanks daughter-of-mine. 👍
