Can we print a 3D object with a 2D printer ? Cheap ? And time consuming like if you build it from scratch ?

Maybe we can try at least :) Here is a solution for you ;)

We will need :

An internet connection with a computer or tablet
Slic3r software program and imagemagick
Paper sheets (80g = 100 microns thick)
A paper pencil
A paper sheet
Glue
A lot of time :)

That is all folks ! Let's print something :)

Step 1 : Download your 3D model

Modeling a 3D model is possible but not always really easy. Here we are going to use an online 3D object head

Step 2 : Reduce and slice your 3D model

Here you will need the software program Slic3r, to reduce and slice your 3D model.

To reduce :

Press Add select head_with_eyes_rectificada.stl

Then Object - Scale - Uniformly and 50 percent

File save head_with_eyes_rectificada_50percent.stl

To slice :

In Printer Settings - Nozzle diameter : 0.5 - Layer Height : 0.1 mm

Then File Slice To svg

Choose head_with_eyes_rectificada_50percent.stl
Then head_with_eyes_rectificada_50percent.svg

Step 3 : Copy and cut each slide

Goto svgviewer
Drag and drop head_with_eyes_rectificada_50percent.svg
Copy each slice with this script capture.sh :

#!/bin/bash

number=0
echo "record screenshot png"
echo "BEWARE : DELETE ALL PNG CREATED BEFORE !!!!"
read -n 1 -s
rm -f *.png
echo "select firefox"
sleep 5
while true ;
do
    import -window root "screen.png"
    xdotool key Right
    new=$(printf "screen%04d.png" "$number")
    mv -- "screen.png" "$new"
    echo "$new"
    number=$(expr "$number" + 1)
done

Renum each slice with this script renum.sh :

#!/bin/bash

number=0
for i in *.png; do
    new=$(printf "renum%04d.png" "$number")
    mv -- "$i" "$new"
    echo "$new"
    number=$(expr "$number" + 1)
done

Crop numerically each slice with this script crop.sh :

#!/bin/bash

number=1
for i in *.png; do
    new=$(printf "crop%04d.png" "$number")
    convert -crop 68x72+109+479 +repage "$i" "$new"
    echo "$new"
    number=$(expr "$number" + 1)
done

Number each slice with this script num.sh :

#!/bin/bash
number=1
for i in *.png; do
    new=$(printf "num%04d.png" "$number")
    convert "$i" -gravity southeast -stroke '#000C' -strokewidth 2 -annotate 0 "$number" -stroke none -fill white -annotate 0 "$number" "$new"
    echo "$new"
    number=$(expr "$number" + 1)
done
