Local School Student Category
Top Prize: Slicer
School: Raffles Institution
Individual
Slicer is a cost effective, versatile kitchen cutter that is safe, reliable, and powerful. Take all the annoyance and injuries out of preparing a meal!
Safety – Orientation & direction of the knife is positioned such that it cannot cut the user. The cutting board is also made of food-safe PETG material.
Durability – Slicer uses premium components (e.g. linear rods & bearings) typically found in high precision machines; as well as strong 3D-printed parts which are extremely difficult to break. This guarantees it will last for a long time.
Performance – Slicer’s large cutting size (10x10x20cm) fits most vegetables & fruits. Its powerful motors & gear amplification generates extremely high torque and powers a sharp ceramic blade.
Maintenance – The ceramic blade does not dull easily and thus requires little sharpening. The magnetically-attached cutting board is easily detachable for washing.

1st Runner-up: Sweeper Cart
School: Tampines Meridian Junior College
Team of 3
Taking into consideration how tedious and mundane sweeping can be to many people, we decided to make sweeping more hassle free by attempting to eliminate the need to carry around both a broom as well as a dustpan during sweeping. Furthermore, we also want to reduce manual input from the user as much as possible. Hence, we designed the “Sweeper Cart”.
The “Sweeper Cart” comprises 2 main features. The first of which is a rotating front bristle wheel that is responsible for sweeping litter. The second is the dustpan-like collection area where the litter is swept into and stored for later disposal.
Similar to a vacuum cleaner, the user simply has to push the cart forward and have the rotating bristles sweep litter into the collection area. This eliminates the need for the user to manually sweep with a broom. Furthermore, unlike a vacuum cleaner, the “Sweeper Cart” does not require electricity to operate which makes it more cost effective.
The parts that make up the “Sweeper Cart” were all 3D printed with PLA using FDM printing.

2nd Runner-up: LedgeBeClean
School: Victoria Junior College
Team of 2
LedgeBeClean sandwiches itself on the windowsill, moving along wheels while deploying cleaning fluid (baking soda and vinegar) from a tank above the jets. Behind the jets, a pair of gears rotate in clockwise and anti-clockwise motions respectively, scrubbing the ejected solution onto the windowsill to sieve out any dirt. The bristles are velcroid on for easy replacement and maintenance. Concurrently, a second type of removable brush rotates to brush the solution and dirt onto a tray at the back that can be detached to remove the dirt easily. Powered by a battery that would be hidden above the mechanisms, LedgeBeClean can move along windowsills or similar troughs automatically.

Top Prize: GENXpert Scanner
School: ITE College East
Team of 3
In addition to traditional methods in product development, Additive Manufacturing can be enhanced with reverse engineering in the aspect of generating a 3D CAD model for repair, replacement and manufacturing application. One of the key challenges is to obtain accurate 3D CAD Model.
Our proposed solution (GENXpert Scanner) integrates UR Robot with Handheld 3D Scanner with the use of our designed bracket. With this solution, it allows the scanning process to run under the collaborative robot’s control. This will enhance the scanning accuracy, precision and reduce the scanning duration.

1st Runner-up: LEVTOP
School: Republic Polytechnic
Individual
LevTop is a sustainable and an adorable laptop stand that enables you to adjust it’s height and angle individually. With it’s unique design, it cannot be easily copied by wood carpenters. We will be using wood PLA filament to achieve a “jungle” themed product. Although there are many laptops stands that are available in the market, however, based on the market research that we have done, there were none that could adjust your height or angle individually. Even us as the user of an existing laptop stand product in the market finds it a hassle.

2nd Runner-up: Omni-Trolley
School: Republic Polytechnic
Team of 3
Omni-Trolley is designed to assist cleaner to carry and transport heavy-load items such as detergent bottles and sanitisers that will be placed on the two-tiered trays for improved ergonomics and safety.
The number of minor injuries will be reduced with ergonomics and safety factors in mind. It will prevent workers from having difficulties which can lead to overstretching and backaches.
Omni-Trolley has several features as follows: comfortable Trolley height, trolley handles, rotational two-tiered shelves (Trays) with increased depth, able to manoeuvre trolley easily and it is also a lightweight trolley design.
The inspiration was influenced by supermarket trolleys, wagons, and baby strollers. We want this Omni-Trolley to thrive in the market as it can be a gamechanger in the cleaning industries, someday.
