3D paper mache modeling with scotch tape, patplume and liquid latex




Here, what you see is the 3d left ball hip to 50 percent of robotica. It is not printed layer by layer like for the head and hands.


Instead we used the following files as a plan for modeling a patplume model as accurate as possible :
- the 3d file in blender : https://drive.google.com/file/d/0B_g2mleRq27pYWc2V1M5U2FqdTQ/view?usp=sharing
- the svg file cut up and down, drag and drop in svgviewer :  https://drive.google.com/file/d/0B_g2mleRq27pS0cyNFZ4SGJIN28/view?usp=sharing
- the svg file turned cut right to left, drag and drop in svgviewer : https://drive.google.com/file/d/0B_g2mleRq27pbjUzOFl4UU0zMUE/view?usp=sharing


(patplume version, scotch mold, color test on paper with transparent glue)

Then rub it with food plastic and scotch tape to make a mold.
Fill the food plastic and scotch tape mold with paper mache. Wait until it dries.
Then mix liquid latex and paint to put on the dry paper mache.
Or you can replace latex with paint, glue, and food plastic on the glue to protect and make shine the whole thing :)

If you have holes glue a scotch roll in it.

3D paper (80g = 100 microns) printing with 2D printer

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 :

  1. An internet connection with a computer or tablet
  2. Slic3r software program and imagemagick
  3. Paper sheets (80g = 100 microns thick)
  4. A paper pencil
  5. A paper sheet
  6. Glue
  7. 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

#!/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
  • montage contour white each slice
montage num*.png -tile 10x14 -geometry +1+1 montage.png


  • Assemble in gimp into a printable png a4 file for 2D printing

  • Cut each slide following the pencil lines

Step 4 : Glue each slide from up to down


  • Here is the low tech 3D printer : a box of cereales ;)
  • On the left corner is two slides one with six previous slides and the last one
  • So then you add an other slide at the bottom
  • You adjust on the corner the previous slide and the new one
  • Glue the both together
  • Then take the upper slide off
  • And again with the next slide
  • Go Go Go

 Step 5 : Admire your artwork :) or not ;)

 

 Step 6 : Add paper mache or patplume for details

This is the end my friend :) You can practice more with that better explanation than mine :) Thank you for your time :)

3D cardstock printing without printer

Can we print a 3D object with no 2D or 3D printer at all ?  With no third party online service ? 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 :

  1. An internet connection with a computer or tablet
  2. Slic3r software program
  3. Cardstock like cereals box about 400 microns thick
  4. A paper pencil
  5. A paper sheet
  6. Glue
  7. A lot of time :)
That is all folks ! Let's print something :)

Step 1 : Download your 3D model

  • File save head_with_eyes_rectificada_50percent.stl


To slice :


  • In Printer Settings  - Nozzle diameter : 0.5 - Layer Height : 0.4 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

Step 4 : Glue each slide from up to down

liani sintel version arduino arm moves z axis test 001



So here is a little test of the left arm animated by a micro servo with a arduino.

You can get the code here

Beware to change the serial port for your system or it will bug ;)

Now it is time to do x and y axis ;)

For that i had to buy a breadboard, wires, and 4 micro servo on amazon at une brillante planète (you know them ?) for 12 euros with free delivery. I will see what it worth don't really know but it is very cheap.

liani sintel version automata walk cycle test 001



So long time no post... because i was working on the abilities to draw, sculpt, model, design, i was trying to design what liani will look like...

but nothing happens...

 no design, no sketch, no model was good enough... i tried hard but i was blocked.

However i was watching Sintel on youtube and bam, that is it. Sintel character is creative common i can use it and pass the design block.

So here is a liani sintel version automata walk cycle test 001 hand activated :)

The head is a pocket digital photo frame with a creative common attribution sintel face (to improve with an arduino mini screen)

The body is for now in paper (to be printed with a better texture next time)

The automata system is in lego for now (to improve by a laser cutable material or 3d printable)

The goal is to make a little animatronic doll of 15 cm (5.90 inches) that moves good :)




The work now is to make a hand moves in x y z with 3 micro servo, (or flexinole) and a arduino...

So what do you think about it ? Thank you for your feedback :)

More modeling chibi liani doll head and latex skin test

When you are building something, it is very important to have feedbacks. You can ask friends or else, but they are not really reliable. Because if they like you, they will probably say : "AMAZING !" and if they hate you, it will be like : "NO WAY !". Last but not least, if you have friends who hate you : "RUN, they are not your friends anymore ;)"

So here we took a really good bjd doll forum for feedbacks (google translate is your friend ;) :

http://www.materielceleste.com/t49521-liani-dolls-libre-animated-dolls

This forum is full of good advices :) so "release early, release often" ;)

So we had to improve the jaws and the quality of the picture. It seems that we have to put the camera very close to the object to improve the render. In fact, now we can see all the mistakes ;(

So here is the new chibi liani head modeling :



We tried to make a skin test. Plastiroc is often used in bjd doll prototyping but really discouraging for the beginners (hard to work, long to dry). Here to ease the process of sculpting it could be great to model in pat'plume and make a skin in latex.  

It is cheap and fast but it is not as clean as Plastiroc and surfacer.


And here is a previous latex skin test to have an idea :




The chibi liani head modeling has started too. We use blender and we have learned to use it with Neal tutorials and Angela tutorials blenderella. Don't forget to shop if you can ;)


You can improve the .blend file :)

Modeling chibi liani doll in patplume

After sketching what you planning to do. Now it is modeling time ;)

So before doing anything, you will have to learn how to model. To do that, you can use youtube or the future tutorial i will put on here ;). For this modeling, i used Berit HILDRE book, her modeling and characters are really awesome, sooo full of live. And i used sculpture techniques -miniature head sculpting of Jordu Schell from Stan Winston School too. But more and more practising are needed ;)

Which modeling materials to use ?
- un pen and a cap pen (really important)
- a knife
- color pen and water paint

Then there are all sorts of materials : clay, dollputty, plastiroc, fimo... that you have to put in oven or not, dry fast, slowly or not.  Here patplume have been used because :
- safe
- cheap
- no oven
- reusable
- paintable
- latex friendly

After hours of hard work, here is the result :


And a finger spinning doll head on Mozart (because it is great and public domain, copyrigths expired)
