About NEO Aeronautics

NEO Aeronautics is incorporated in 2018 with the focus to design and produce manned personal aerial vehicle (PAV) that is safe, reliable, and affordable; and to build Urban Aerial Mobility (UAM) communities globally.

Since the company’s inception, we have developed two prototypes, Crimson S8, of the PAV as proof of concept. Covid-19 has slowed down our product development. With the opening of the economy, we are ready to build flight trial and certification version.

Currently, the regulations in Singapore does not allow for personal aerial vehicles to be operated in the open, thus we plan to test and certify the vehicle in the United States. The unmanned version will be tested in Singapore. As the PAV is developed as an “ultralight vehicle” under the US Federal Aviation Administration (FAA) Part 103 rules, anyone would be able to use it. Under US law, operators of ultralight vehicles do not need a pilot license.

Apart from using it as a personal mode of transport from point to point, we are also plan to roll out the PAVs for the tourism market. We plan to have the vehicle built and tested locally in an unmanned mode in October 2022.  Thereafter, we will test and certify the vehicle in manned mode in United States in early 2023. Our goal is to have 1,000 of our PAVs in 25 cities making 50 million trips yearly.

Annex 1

‘The SIT Hackathon 2022: Sustainability in Space’ in its entirety comprises the following components:

Theme: How To Live In Space For 365 Days?

Sustainability in Space: Currently, space missions require excess equipment to be prepared for unforeseen circumstances.  When necessary, rockets are launched to transport equipment where requirements are deemed mission critical.  Sometime this leads to waste and inefficiency.  Technology such as 3D printing or smart indoor farming can allow equipment, resources or even food to be produced as needed.  This will help to reduce excess equipment to be transported and reduce the need for additional rocket launches.  Hence, making space activities more sustainable.

Mission Statement: Research and innovate solutions related to 3D printing technologies that can be used in space to achieve sustainable living.

Entry Stage (19 Jan 2022): Teams of 3-5 students per group to submit a 2-page proposal & 5 minutes video to address Mission Statement.  Six teams submitted the initial proposal by the deadline, addressing the mission statement and progressed to the next stage.

Idea Conceptualisation Stage (19 Mar 2022): Idea conceptualisation where students work with their respective assigned mentors to produce their prototype.  A budget of $500 was provided to the students to work on their prototypes.  All teams will also have access to RaPiD and Food Technology laboratory for support.

The Grand Final (8 June 2022): Four finalists will present their solution to the mission statement to a panel of judges in a 10 to 15-minute live presentation.

Cash prizes for Grand Final participants:

o Top 3 Awards: $500

Annex 2: List of Winners


Winning Team & Members


($500 cash)


Cooked food is sent up to the International Space Station (ISS) via a spacecraft every 90 days.  This is because cooked food does not have a long shelf life. Along with food, the spacecraft might carry additional items required for logistics or repair work. These items being sent to the ISS require proper packaging to ensure that they are kept safe during the journey. However, should an emergency happen in the ISS where repair parts are needed before the next scheduled spacecraft flight, one will have to be launched immediately. REPA is proposing to 3D print repair parts/components in the ISS, where the filament needed for printing is made from the plastic packaging used to store the items brought from earth. The objective is to reduce the number of spacecraft trips to the ISS or allow spacecraft with smaller payload to be sent instead of the larger one, hence trimming the operational cost. This idea would require two machines to be sent into the ISS, one to shred the plastic packaging and one to produce the components/parts.

2nd place

($500 cash)


With the decommissioning of the ISS approaching, there is a need to re-establish a space station in outer space. However, building another space station through conventional means is costly and risky.

Team AMICA proposes the development of an Advanced Manufacturing and Innovation Capsule (AMICA). AMICA will be equipped with 3D printing technology, consisting of an in-built, dual bed 3D printer system with three axes of maneuverability, a multi-nozzle print head capable of printing objects in various materials, a segregated control room for monitoring and controlling purposes, an attached furnace for metal post-processing work and lastly, remotely controlled robotic arms situated outside the capsule.

AMICA will be able to expand the space station by printing modular sections of the outer frame internally and assembling them through internally controlled robotic arms, paving the way for the modular expansion of the space station. Spare parts and tools can be printed on-demand, saving costs and precious cargo space during resupply missions.

In the future, a space debris recovery capsule can be attached to promote self-sufficiency. This allows for the capturing of space debris to be broken down and recycled to produce powder bases or filaments to print other 3D objects, saving costs and space in resupplying missions. Moreover, this would also address the growing concern of orbital debris, tapping into tons of valuable resources that would otherwise be disintegrated or lost.

3rd place

($500 cash)


A rocket launch and its colossal payload currently emit tonnes of harmful gases into the atmosphere. In addition, astronomical costs are associated with each launch, making sustainable living in space difficult. To that end, Team Legstronk proposes the reduction of payload by using material found on the lunar surface to produce building foundations by adopting the 3D printing layering concept.

This is opposed to carrying large masses of man-made material on-board the rocket for foundation production. In this way, the weight of payloads entering space and hence, the volume of emissions will be reduced. The proposed idea aims to allow sustainable living within space, educate the public on existing building technology, and support future space ventures.

Space Construction Vehicle (SCV)

To enable astronauts to survive in space for more than 365 days without resupplies, one approach is to convert space waste into new usable 3D-printed structures that can be connected to a space station. If space stations can fully utilise 3D technology, crucial needs and equipment can be efficiently produced. Ideally, the earth control centre can design the 3D model file of the required equipment or materials and upload them to the space station to allow astronauts to print out the objects when required. This project proposes a Space Construction Vehicle (SCV) that would recycle space waste into reusable materials and perform construction of infrastructure in the space using 3D printing technology.
