Outfitting a Mars Habitat: A 3D Print Challenge
Prepared by GENIUSES SIBU
This is my diary.......
Background:
DAY 1 (2045/10/01)
Day 31 (2045/10/31):
Day 72（2045/12/11）
This is how the greenhouse looks like.
I would like to introduce about its details .
Semicircle outside
Diameter : 4m
Height : 4m
Thickness of the wall : 30cm
I made it by concrete printer.
Semicircle inside
Diameter : 3.8m
Height : 3.8m
Thickness of the wall : 30cm
Space glass
Space glass
I take the space glass
from the landing craft.
And install it on the top of the greenhouse.
So the plants inside can enjoy the light ray from sun .
Ultra-high vacuum
Ultra-high vacuum
In order to have a thermenal insulation effect , I made it look like this.
Little garden
Diameter : 2m
Thickness of the fence : 15cm
Height of the fence : 15cm
Thickness of the chassis : 5cm
I decided to mix Mars dirt with my feces for planting. I will use leftover potatoes from my landing craft for planting.
passage
This passage is to connect my landing craft with the greenhouse , so that the oxygen generated
from the greenhouse can pass through ,
and the carbon dioxide I exhale can pass through the greenhouse for exchange.
Outside
Length : 3m
Height : 2m
Diameter :2m
Inside
Length: 3m
Height : 1.9m
Diameter : 1.8m

Day 73 (2045/12/12)
This is how the shovel
looks like.
I made it by plastic and metal printer.
I would like to introduce about its details.
Handle ,I made it by using plastic printer.
Length : 31cm
Handle
Diameter : 4cm Height: 15cm
Chassis of handle
Diameter :4cm Length :2cm
Central ring of handle
Diameter : 4cm Height : 0.7cm
Top of the handle(little cylinder)
Diameter : 4cm Height : 3cm
Cylinder in the central section
Diameter: 2.4cm Height : 10cm

Metal part of shovel
Metal part of shovel , I made it by using printer metal.
Width : 12cm Length : 16cm Thickness : 0.3cm
Mainstay (include the part of front)
Height : 8cm Width : 2cm Length : 2cm
I deisgned a little screw and a connector , so i can assemble them together.
Let me show you.

Length : 4cm Diameter : 1cm
Day 137 (2045/02/04)
Food was solved but water had not . So, I wanted to go to the polar climate of Mars to get the water ice. Before this, I must to solve my shipping problem, I needed to create a wrench and repair the broken tire.
This is how the wrench looks like.
I made it by using metal printer. There are A and B sides , I also designed a little screw and connector at the middle of the mainstay, so i can assemble them together. (the reason of why it so long)
Length : 30cm Width : 6cm
Mainstay
Length : 18cm Thickness : 2cm
B side of wrench
Diameter : 6cm Thickness : 3cm
B side of wrench
A side of wrench
A side of wrench
Diameter : 6cm
Thickness : 2cm
Blank space (A side of wrench)
Diameter : 3cm
75 degree
Mainstay
Blank space (B side of wrench)
Length : 4cm Width : 2cm
Day 167 (2045/03/06)
After I have done the spanner, I started to repair the tire and finished it. I finished the repair by using the wrench I made. In addition, I also did some optimizations.
Width : 40cm
Diameter : 50cm
Blank space
Diameter : 30cm
I made a gear to fill the blank space.
The outer side of the tire is made by the concrete objects.The part in its center is missing.
This is the broken tire , I observed it.
Part 1
Part 2
Part 3
Part 4
Because of its big bulk(gear) , I made it four times apart.
One of the part
90 degree of a circle
Height : 3cm
Width : 15cm
Perimeter : 17.27cm
[(22/2 *3.14*2)/4]
Gear tooth
Length : 2.5cm
Height : 3cm
Width : 15cm
Finally , I used the metal printer to combine them become a full gear.
Gear tooth
The gear was made by metal,
I also leaves some space (1cm distance) because it might get
thermal expansion and contraction.
Day 170 （2046/03/19）
I noticed that water was not enough right now, I decided to make ice-chisel for get some water ice at polar climate of Mars.
ICE CHISEL
handle
screw
Metal part of ice-chisel
This is how the ice-chisel looks like. I would like to introduce about its details.
Handle , I made it by using plastic printer.
Diameter : 5cm
Height : 30cm
Metal part of ice-chisel, I made it by using metal printer.
Length : 45cm
Width : 5cm
Because of its large number of length , I made it three times apart.
Let me show you.
Part 1

I also designed a screw and a connector, so i can combine them together. Let me show you.
I made Part 2 bigger , so I can exert centrigual force when I cut ice.
When the metal part of
ice-chisel or handle is damaged, I can change one of them easily and immediately , so the whole will not be wasted.

Day 173� (2046/4/01)
Everything was prepared, I also brought enough water and food for my survival. After filled up with fuel(from my space lander), I started to go to polar climate of Mars by my new rover.
Day 173（2046/4/01）
After a day of long trekking, I arrived the polar climate of Mars. Then I started to collect water ice.
Day173
(2046/4/01)
Finally, I had collect enough water ice. The amount of ice is enough for my water usage for the second half of the year in Mars. Then I put all the ice in trunk of my rover. After everything finished, I started the journey to the rehabilitation base.
Day 365 (2046/10/01)
Today is my last day in Mars because NASA will take me home. Finally, I can come back to Earth. I finished the lonely life.
