High-Level Project Summary
To equip a habitat on Mars with humans we need optimal conditions such as oxygen, temperature, water, food, energy, and shelter. However, current technology allows us to use 3D printers of different materials, which, equipping a habitat is quite a challenge!The 3D – Polis team proposes to develop a bank of 3D objects which can be materialized using plastic, metal, and concrete 3D printers. This bank will have models such as Furniture (bed, shelves, desks, table, chairs, and others.), Multipurpose tools (screwdriver, cutter, filer, drill, even vacuum cleaner, and blower), and also objects for the distraction of the inhabitants.

Detailed Project Description
Details:
The 3D-Polis team developed a bank of 3D objects which can be materialized using plastic, metal, and concrete 3D printers with limited printing areas.
The objects were modeled using different design tools such as Solidworks, Blender, and Tinkercad, and we also used 3D models that provided the resources of the chosen challenge.
Next, we are going to list the bank of 3D elements developed along with their functionalities and benefits for a manned mission to the red planet.
3D Models:
- Bed with desk and organizers
- Seeds Germinator
- Mini Drill
- Wrench
- Infinite Cube
- Chess
- Table
- Chairs
- Perseverance or Curiosity Wheel :O
- Multifunctional tangram (Very interesting ;) )
- Multipurpose tool
- Other tools, furniture, entertainment thinks
- Infinite possibilities (Sky is the limit :D )
Bed with desk and organizers
This 3D model is intended to be printed in parts on a concrete printer.
These parts are modeled with the intention that they can fit together in order to obtain a two-story piece of furniture as a final result. At the top is the bed which can be accessed from both sides of the bed by means of a "ladder" that includes the same design.
In the lower part, the user will be able to have access to a fairly large desk and countertop furniture where they can store their different tools for work, learning, and also entertainment.
The benefits of this model is that, as they are flat models, printing can be done more quickly. In addition, this model is modular and can be easily transported.
The model is easy to assemble and very resistant, as well as saving a lot of space by having three pieces of furniture in one.
Seeds Germinator:
This 3D model allows you to have a tool where you can germinate seeds in an easy, fast, portable, modular, automatic and functional way.
This model has 24 slots per floor to put different seeds. In addition, they will also use an automatic irrigation system through a water dispenser that will keep the seeds moist for proper growth. It will also use white light led strips and UV led strips to be able to provide the seed with what is necessary for its germination.
Several floors can be added vertically as the user allows, all floors share an irrigation system, so there is no need to implement extra functions.
This has benefits of saving space, and also getting a system so it can be the first step to growing your own food.
Mini Drill
This 3D modeled tool has two pieces which work by moving one of the pieces from side to side, which will cause the central piece to rotate on its own axis.
At the other end, there will be a bit holder which allows the user to have different bits such as a drill, sandpaper among others, the possibilities are endless.
The benefit of this tool is that it does not consume extra energy such as batteries or electricity. It is completely manual and functional.
Wrench
This 3D-modeled tool allows the user to turn nuts of different sizes. It can be printed in one piece quickly.
The benefits that this part offers is that it can be adapted to various nuts. It is a small and fast printing model.
Table
The design of this piece of furniture was based on saving space, without losing its proper functioning so that each person can work on top of it comfortably. Also, the design was considered to print it in one piece, using the concrete printer, with a layer height of 0.25; with the purpose of saving material and making it as light as possible, without losing the necessary resistance to be able to put equipment, daily utensils. Finally, the design has the function of coupling with other identical printed tables to make larger tables without any additional modification other than joining them in the way shown in the image.
Multifunctional tangram (Very interesting ;) )
Using the concept of the classic Chinese tangram game, objects were made that can be used as shelves, chairs, small tables, boxes without lids, or whatever the colonizers need, including the entertainment area. These pieces are originally designed to be shelves, small boxes and benches, but it was designed so that they can be printed in different scales and using both the concrete printer and the plastic printer. It has thousands of settings that can help a lot of people residing on Mars.
Multipurpose tool
La pistola multiusos, es una herramienta portatil para poder cubrir muchas necesidades, tanto las de mantenimiento de equipos mecanicos, mecanicos electricos, electricos; como tabien de cuidado personal y de aseo del habitad de los astronautas. La herramienta, tiene una carcaza en forma de pistola para ser hecha con la impresora de plastico; esta tendra un motor DC de 12 voltios con amperaje aun por escificar, accionador, intercambiador de sentido de giro, y un eje el cual servira de transmision de movimiento a los acoples los cuales, seran intercambiables dependiedno la necescidad. Los acoples creados, se unen a la pistola a traves de encajes disenedos para evitar el uso de pegamentos y tornillos; los acoples tambien seran impresos en plastico y algunas partes en la impresora de metal. Las funcionalidades que puede tener esta herramiento, segun los acoples considerados son:
Taladro
Lijadora
Cortadora
Atornillador
Aspiradora
Sopladora, tanto de uso personal como el uso industial
Limadora.
Perseverance or Curiosity Wheel
The designed wheel is capable of using parts that are not yet very deteriorated, such as the coupling disk to the movement axis of the robots, with the aim of saving printing time and metal. The design has an 80 cm long steel bar whose shape will serve to function as a shock absorber in case it is needed, this bar will be joined with the existing bolts to the coupling disc to the robot. The metal bar will continue with a plastic curve that is in contact with the ground of Mars, it has a 60 degree curvature and which has a safe outer layer that will prevent the entry of dust and Martian rocks into its structure, as well of ovoid structures that will give it enough resistance to maintain its shape with the weight and geography of the Martian soil. The plastic part is completely sealed and has a depth of 40 cm and an exterior engraving with triangles pointing to the direction in which the robot moves; It will be printed in two parts and will be glued with the corresponding additives such as resin glue, silicone, etc.
Infinite Cube
This 3D model has the objective of entertaining and having a good time for the user.
The benefit is nothing more than entertainment
Chess
This 3D model is a game for two people to entertain themselves and have a good time using strategies.
Other tools, furniture, entertainment thinks:
We have also developed some models that we want to include in our 3D object database, time is short so the team developed some mockups where you can view the models we have in mind.

- Print 3d challenge of 2018, to know what materials will be used for printing and its composition.
- Google to search for information related to the Roberts wheel and also extra information on the needs that astronauts would have on Mars.
- GrabCad to have inspiration or models that we needed to know their dimensions to be able to digitize them and to be able to make the precise objects for each extra component that you need.
Hackathon Journey
The experience was completely satisfactory and developing solutions to the challenges were a lot of fun. Our team was very committed to the challenge which made the two days of the hackathon very enjoyable.
We chose this challenge because of our passion for technology, space travel, 3D-printed objects, and fun teamwork.
We have worked enthusiastically applying all our skills in 3D modeling, graphic design, research and development, electronics, and technology.
Due to the distance, we could not be present in person for the entire hackathon, however, we have been together long enough to brainstorm and assign responsibilities according to the abilities of each member, in this way we overcome obstacles and generate good content.
We are very grateful to the INNICIA incubator for giving us constant follow-up and mentoring. We also thank our professors who instilled in us an investigative spirit and a passion for technology.
