Yasuhide Yokoi and Final Aim Inc’s Autonomous Delivery Robot

Yasuhide “Yasu” Yokoi is the cofounder of design and technology firm Final Aim Inc., which works with laboratories, startups, and multinational companies to transform ideas into tangible solutions. There, he and his team use Ultimaker 3D printers to better enable rapid design iterations during the prototyping phase.

One of the company’s latest projects is the OSTAW Camello, an autonomous package delivery robot.

Revolutionizing Package Delivery

The Camello was designed to address issues in the delivery logistics chain in Singapore, which causes high shipment costs and operational complexities. Due to low loads and long waiting periods in loading and unloading bays, package deliveries are often inefficient – a fact exacerbated by high delivery volumes and tight delivery deadlines.

To tackle this challenge, Final Aim collaborated with a Singaporean robotics start-up OTSAW Digital PTE LTD, with the Camello being the final product.

The Camello is user friendly, featuring an ergonomic cargo space and sleek design – optimal for Singapore’s urban environment. Plans are currently underway for it to be used by various industrial key players, delivery companies, and retailers throughout Singapore, creating an improved ecosystem that provides smooth and efficient delivery to customers, while increasing profit margins for those businesses that use it.

The Birth of the Camello

As with any product, several phases were involved in Camello’s design, with the Ultimaker S3, Ultimaker Cura, and CAD software acting as Yasu’s and Final Aim’s greatest companions throughout the process.

First came the robot’s concept development and evaluation. From the initiation to ideation, he used both hand-drawn design sketches and CAD software.

Once he developed the idea, Yasu began the process of presenting it to the higher-level management, frontline members, and end-users. This divergent approach allowed Yasu to gain as much feedback as possible, which he could then use to refine, improve, and further flesh out his concept.

Next came the prototyping phase. As Yasu now had numerous potential ideas, he needed to rapidly actualize them – often on tight deadlines. Luckily, this was a task that 3D printing was able to easily handle. Compared to other common prototyping methods such as sculpting or carving from Styrofoam, chemical wood, or industrial clay, 3D printing is much more efficient – freeing up time for Yasu to work on other design tasks.

“More than just cost-cutting, 3D printing has added value to my process,” Yasu said.

Finalizing an Intuitive Design

Yasu was also responsible for ensuring that the Camello’s final design was of excellent quality. As his works often incorporate organically curved surfaces and silhouettes, which are often difficult to implement, he needed to create numerous iterations. 3D printing technology utilizes the contour layers of printouts to analyze the curvature of surfaces – essentially an equivalent to the zebra mapping that CAD software performs.

“The Ultimaker S3’s double extrusion feature has [also] been essential to my everyday design applications,” Yasu said. “Together with Breakaway and PVA material, my printing experience has become exponentially more efficient. I am deeply satisfied with the resulting quality as it leaves behind no support structure remaining.”

For the Camello to be a success, its design had to be intuitive and accessible at first glance. The design process, therefore, involved divergent ideation, exploring all possibilities, which were then carefully narrowed in focus. Development speed was also critical for stakeholders’ requests.

3D printing enabled these stakeholders to see and touch a physical product, deepening their understanding of the Camello’s concept and design – and streamlining the decision-making process.

Slicing A Model File With Cura

General Overview

Cura and other slicing programs transform a CAD model (STL, OBJ, 3MF) into a set of machine instructions that tell your printer how to create your model. There are hundreds of settings that you can control within Cura. Everything from layer height, speed, fan settings, acceleration, jerk etc. Cura comes with pre-made profiles for ease of use and to ensure quality, and it is highly recommended starting with these for all of your prints.

In this support article, we will cover everything you need to know in order to get a print up and running using Ultimakers Cura Software.


Download and Install

Cura is available for Windows, Mac OSX, and Linux operating systems. Ultimaker updates Cura on a regular basis, so be sure to check back for the latest free updates. You can find the most recent version available for download here. After installing the program appropriate for your Operating System, launch the program to prepare your file.


Machine Addition and Selection

After launching the program, you will be prompted to select a machine. In this walkthrough, we will be using the Ultimaker S5. If you are using another Ultimaker product, please ensure to select that machine that corresponds with your product.

Should you ever need to add a new machine for slicing, you can gain access to this same menu by going to the top menu of Cura and going to settings > printer > add printer.


Print cores are compatible with specific material combinations, and it is important to have these properly selected each time you slice a model file.

At the top of the main Cura prepare screen, you will see which current materials and print cores you have selected. Clicking the drop-down arrow on the right hand side will allow you to change the cores as desired.

NOTE: If you have an incompatible material with your print core, a red box will appear and prevent you from slicing your file.


Loading Model and Print Orientation

You can load your print model in one of three ways:

  • In the top left corner, go to File > Open File(s) > Select Model File.
  • In the top left, you will see an “Open File” icon.
  • You can drag and drop your model file onto the build platform representation.

After your model has been loaded onto the platform, you will want to consider how to position it for ideal printing. In general, you will want a flat surface on the build plate to help with adhesion whenever possible.


Quick Profile Options

When first starting with your 3D printing journey, you will want to remain within the recommended settings as provided within Cura. These settings will help ensure reliability and quality for the vast majority of models you will print.

  • The Profiles section will allow you to set layer height based upon different factors such as visual look, engineering quality, or draft settings.
  • The Infill (%) section will allow you to determine how solid your model file is. 10-20% is perfectly fine for most non-load-bearing components.
  • Gradual Infill option will print your object with less infill lower down in the model and increase as the object prints to help support the upper skin of the print.
  • Support generates support structures to help your object print overhangs and steep angles. A general rule of thumb is your printer will not require supports if your model is between 45 and 90 degrees of the build plate.
  • Adhesion is turned on by default for most profiles and helps secure your object to the build plate. It does this by increasing your objects footprint, by printing lines around the base of your object.

Generate and Print Your File

After you have your model positioned and changed any settings you desire for your application, it is time to generate the print file and get it to your printer. The process of generating your machine directions is called “slicing” as it cuts your model into slices to generate the code.

Slicing Your Model File

  • Automatic Slicing can be enabled through Preferences > Configure Cura > Enable Automatic Slicing. When enabled, Cura will automatically begin to slice your model after each setting change. This can be an intensive load on your computer and is recommended to disable this for older computers.
  • When “Enable Automatic Slicing” is disabled, Cura will wait to generate your file until you select “Slice” from the lower right-hand corner.

Printing Your File

Ultimaker provides a direct printing option via USB or allows you to send your print file over the network.

  • Printing via USB will require you to save your print file to the piece of hardware, and manually insert it into your printer. Once inserted, you will be able to select and start your print file from the user interface on your printer.
  • Printing over network requires you to sign into your Cura connect account, and you can then send the print file directly to your machine. This can then be started through the user interface on the panel or through Cura connect interface within Cura.

Removing Prints From Ultimaker

Print Removal Techniques

After your print has completed, it will need to removed from the glass build plate. There are a few separate techniques to accomplish this, and each can have advantages depending on the specific part and whether any additional adhesives were used.


Wait For the Glass Plate to Cool Down

If you printed directly on to the glass plate without using an adhesive, and if the build plate was not leveled too tightly, the print may easily be removed once it is cool. Simply allow the build plate and the print to cool down after printing. The material will contract as it cools and you can easily remove the print from the build plate.


Use a Spatula or Scraper

If your print doesn’t remove from the build plate after cooling, you can use a spatula to remove the print. Place the spatula under the print and apply a small amount of force to remove the print.

NOTE: Take the glass plate out of the printer to avoid damaging the build plate clamps.


Use Water to Remove the Print

If neither of these methods work, remove the print using water. Remove the glass plate and print from the Ultimaker. Be careful not to burn your fingers if the glass plate is still warm. Run cool tap water on the backside of the plate to cool it quicker – the print material will contract more than during a normal cool down. Once the plate has cooled, the print can be popped off.

If glue or Magigoo was used on the glass plate, run lukewarm water over the print side of the plate to dissolve the glue. Once the glue has dissolved, it should be easier to remove the print. If PVA was used, place the glass plate and print in water to dissolve the PVA – this makes print removal easier.
