printing a big spoon...

Recommended Posts


I try to print a big spoon with PLA 210°C, 75°C heated bed, 50mm/s:



The results are here : https://imgur.com/a/Ss6Yw


I tried to print it vertically with meshmixer support with brim in cura with 30 loops => no success, not stable enough

I tried to print it vertically with cura support and brim with 30 loops => not stable enough

I tried to print it horizontally with meshmixer support => not enough adherence on glass... even at 25mm/s


Do you have an idea of to print this ???

Blarp, I wrote this whole thing before I realized you had other pictures in that link; so I'm starting over again.

It's a bit difficult to tell from the image, but are the back of the spoon and the handle of spoon on the same plane, and is the back of the spoon flat? If so, you may be able to print the spoon rotated so it's flat with zero support.


I would think that you could print that spoon upright; and that vertical may be the best orientation. Increase the density of the support material, and if that doesn't work also change the overhang angle to a lower value this will make the support material both bigger and denser allowing it to stack better. It's difficult to see in the Cura support example why the print failed, so I'm not too sure these suggestions are accurate.

Also reduce your heated bed temperature. Default of 75 is to high for PLA. Something like 60 works for me but I have a own build bed. Did you also clean the bed from fingerprints? If you still have problems try to apply the glue stick or a 1 part woodglue (that white stuff that is solvable in water) + 2 or 3 parts water solution as a very thin layer.

Cura only adds two supports at the left and right side. The PLA was too melted and the supports had fallen into the sides.

The bed was cleaned with a new thin layer of glue.

The spoon is not flat... I will try with a lower bed temperature and heavier supports.

Thanks for advices.

This is a difficult print. It should be printed handle down as shown in your cura photo and if the bottom of the handle isn't perfectly flat you need to sink it lower into the bed for good contact (cura setting in quality). 75C is a bit hot and causes a slight "warping" on the bottom 3mm of the handle but that's not your problem (but to fix it go to 60C bed). The main problem is where the handle starts to get wide - you have 45 degree or so overhangs and this will caused raised edges that the nozzle can hit and knock it over. You need that thing tied down really solid. it will get hit hard! Maybe 1kg force. Once you get to the center of the spoon the rest is easy.

30 loop brim was smart.

So what is the fix?

Meshmixer. I know you tried it but you need very strong support. Do 2 10mm diameter supports and taper them to about 2mm support point touching on either side of the handle. Also add 4 more supports on the print bed that go half way (or 2/3) up the meshmixer supports to support in both X and Y.

Also fan must be 100% when you get to the tapering of the spoon. This is critical. And don't go thinner than .1mm either as that will cause problems with the overhangs.

Alternatively you could go old school makerbot with cura raft and support. But this will cause a very ugly surface.

Hi, yup George is right is it a difficult print. If you are still failing vertically then I would try…

1.Lay the spoon horizontally with the indent in the spoon face facing downwards. If the rim of the spoon face is not touching the bed, then bury the handle so the rim is facing the bed

2. as before but if the rim is touching the bed and the handle is raised above the bed then use support for the handle. And then be prepared to spend some filing/smoothing time to repair the damage J

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
