Orienting the spoon slightly sideways at about 40 degrees and then letting Preform create supports.
Have to still test if there is a better orientation.
The clear Resin I used in printing the spoon is not food safe! See info in summary to make sure not to misuse 3DPrinting for objects that get into contact with food or your mouth.
How I Designed This
As always I used Cinema 4D as the tool of choice. I used hypernurbs with a low poly version of the spoon, to keep it easily adjustable to Elsha's needs.
Food Safety and Molding
Important info on food safety and 3DPrinting: Use 3D Printed objects on your own risk and get yourself informed well, not all materials are safe and not all production processes are safe
Food Safety and 3D Printing
I found info on food safe mold making and food safe resin but there is more than just using food safe materials to producing foodsafe objects (e.g. material of mold, surface structure of the finished product...). I couldn't find any "food safe/grade" resin in europe(Germany), maybe due to different regulations. I found info on Injection Molding with certain materials that are said to be food safe (like PET https://en.m.wikipedia.org/wiki/Food_contact_materials)

3D Printed Molds for Injection Molding
Step-by-Step | Create Mold and Cast Spoon
Create food safe mold and cast the spoon in food safe resin
The materials you need:
Vaseline (just regular, you can get at a drugstore or beauty shop)
Resin to cast your spoons with: e.g. https://shop.resinobsession.com/collections/resin/products/alumilite-amazing-clear-cast-epoxy-resin-16-ounces?variant=1195651921
Putty/Silicone to make the mold out of spoon: e.g. https://shop.resinobsession.com/collections/mold-making-materials/products/alumilite-amazing-silicone-putty-kit?variant=965318805
If you find other resources for food safe resin and silicone that's perfectly fine too, as long as you follow the suitable instructions on molding and casting.
Optionally you can spray coat the real spoon with a thin layer of food safe lacquer before molding, to go super safe and avoid any chemicals leaking into the mold.
In the first two links(resin and putty) they have videos on how to use the products, let your friend watch these plus my instructions below.
Make a first test with a spoon you do not need, to make sure that everything works fine, before using the spoon you really want to cast
That is how I would do it (sadly I cant test it here, I do not have these materials here) - Step by step:
- Follow those instructions to make the mold of a test spoon https://www.youtube.com/watch?v=ag-QOJV_M_k
(this is an alternative if you got cheap food grade silicone and corn starch https://www.youtube.com/watch?v=UhkhIT93NEM)
- Let the putty cure as stated in the video or the instructions on the package
- Cut your hole at the tip of the handle
- Follow the instructions in the same video on using the resin to make the spoon
(Rubberbands can be used to hold the mold sides together)
- As the state when the piece is not fully cured clean it up
