first prototype printed with ABS plastic, took 3 hours.

Looks good! I had no idea a 3D printer could take that long. (I'm sure there are industrial versions that would be a lot faster.)

yes, they might have better machine, but lead time longer, unless you pay extra.
Just check quote from https://express.stratasysdirect.com/, for this part (FDM ABS Black) they ask $136 next day shipment or $99 by Dec 13.
Using 3Dhubs.com services you can print it for $20 - $30 in most places with acceptable quality for this purpose

A friend told me he just got a 3D printer for less than $300. The first two jobs went well. It got confused during an 8 hour job he left going overnight. I'm excited to see the prices coming down with some units well below that price, and you're right, for a drip tray that's hidden anyway, it doesn't need to be high resolution.

An industrial printer wouldn't be that much faster. The printing time is just a limitation of the 3D printing technology that exists today. A milling machine will do it faster for sure, but at a cost.

I highly recommend the Zortrax 3D printer if using 3Dhubs.com. Otherwise, Sculpteo of Shapeways offer excellent print quality in various materials. You can even get gold! For a price, of course.

I run a 3d printer daily to produce my 3d cad designs. 3 hours sounds about right for that shape, considering its size and resolution. You get what you pay for in resolution, and I see some blips and smears in the perimeter of the flat bottom of the bowl. The stairstep ledging that exists in the wall as it enlarges is an example of the resolution limitation of that machine. Not that it matters here because its normally out of sight, but this is typical of retail printers. Industrial printers up the scale of the printable bed, as well as offer a bevy of material choices, as well as enclosed heated chambers, all of which leads to more stable and robust outcomes.

You might want to consider out of the box ideation here in attempt to gather a range of alternative methods.

If you were to print the male form through 3d printing, then vacuum form it, using a variety of plastic sheet materials would be potentially successful, and repeatable for less cost than printing every bowl. If you were to make, say, 20-50, this would be worth considering. Low cost.
Because the perimeter of the tray is flat and can be hand cut, I'd probably give a try at slumping acrylic over a sphere shape with a heat gun and trimming the excess.

A rubber or rigid mold into which you could cast urethane or flexible silicone (or other elastomer) positive output in a semi repeatable process is an option. The elastomer family offers better heat resistant materials for hot drips from the PF. A plaster mold of your 3d prototype could be effective as well.

An x carve or shopbot machine could mill out that shape fairly quickly, if you consider reductive processes instead of additive technology like 3d printing. It would leave a fair amount of waste material behind, but it would be quick and precise.

Lots of options- sorry to throw them in at this point in the process....

please keep in mind, that printing was made just for fitting purpose, to verify design. Once it confirmed I will publish updated design file and anyone can print it using service of their choice.

I find it interesting to read about alternative processes for fabricating parts like this. In any case I appreciate Sergey's generous help in creating a part that can be accessed by anyone, open source. Soon I'll have the drip tray that he's sending me to confirm that it fits.

The tray turned out great! It's amazing that people can make things like that at home, who would have thought 3D printing would be around in this day in age? So the big question, how does it fit and how does it look in the machine?

Thanks again for posting the great pics of this project, I've never seen this type of work done before so it's definitely educational to me!

The tray arrived today and fits very well in my 1st gen machines.
