Valentines Day is also my birthday, and even though it is my birthday, I always make a valentine for my valentine!

This valentine consists of two parts; a dual extrusion 3D printed heart figure ("Heart.3mf"), and a dual extrusion 3D printed banner (I've included two, "BannerXOXO.3mf" and "BannerBeMine.3mf").

Designed using Autodesk Fusion 360, sliced using Cura 3.1, and printed in PLA on an Ultimaker 3 Extended.

Materials and methods

I printed all parts at .15mm vertical resolution with 20% infill.

I printed all parts on an Ultimaker 3 Extended in Ultimaker Red (extruder 1) and Ultimaker White (extruder 2).

"Heart.3mf" is the dual extrusion file for printing the heart figure. It required about 5 hours to print, 31g of red filament, and 7g of white filament.

"BannerXOXO.3mf" the a dual extrusion file for printing the XOXO banner. I required about 2.5 hours to print, 6g of red filament, and 10g of white filament.

"BannerBeMine.3mf" if a dual extrusion file for printing the Be Mine banner. It required about 2.5 hours to print, 2g of red filament, and 13g of white filament.

Banners can also be made by hand using thick poster board with colored pencils and/or pens. The grandkids are working on some banners for my wife on Valentines Day.

I've included single extrusion versions of the parts "Heart.stl", "BannerXOXO.stl" and "BannerBeMine.stl" for those wishing to print and paint the valentine.

After printing, simply slip the banner into the figure hands.

Omi Sido,

If you load the file "Heart.3mf" into a slicer capable of dual extrusion slicing (for example Cura 3.4.1) you'll see the object in the two colors loaded into the dual extrusion 3D printer.

Before sending the file "Heart.3mf" to a printing company, make sure they have dual extrusion capabilities, and if they do, you will need to specify the colors for extruder 1 and extruder 2.

Hope that helps!

My question comes from the fact that when I upload your .stl file to a program like tinkercad.com I don't see any colours (or at best I suspect the whole thing comes in one colour). Is it possible that I am simply not able to see the colour of the eyes, teeth and hands but when I send the file to a 3D company the heart will come in two colours like your pictures above?

Thanks in advance.

Omi Sido,

I printed this model using a dual extruder Ultimaker 3 Extended, and that's how I placed the face on the heart. My art skills are somewhere between 0 and .000001, so I'm not sure how else I would approach the problem.

I am new to 3D printing so I've got a quick question: how do I pain the hear figure?

Thanks in advance.
