12-Tonne Tank Lifted with 3D Printed Components



Just lately, engineers from Ultimaker, Covestro, and the Royal Dutch Navy got here collectively to reply the query, “How Robust are 3D Printed Components?” Seems, a plastic 3D-printed half can raise a 12-tonne tank.

Normally, engineers measure a fabric’s energy by utilizing a tensile testing machine. Typically, a small pattern print is created and examined below a big power till it snaps. The power projected on the half divided by the floor of the central intersection on the time of breaking will reveal its energy.

Whereas this is sensible to engineers, it typically doesn’t come throughout very effectively to others who might have to see one thing to know the way it works, so that they determined to point out an instance of simply how robust a 3D-printed plastic half may very well be by lifting one thing very heavy: a tank.

Now that may be a enjoyable experiment!


How They Created the First Prototype Design

Designing a 3d printed link for a tank

With the intention to raise a heavy car like a 12-tonne tank utilizing a 3D-printed half, first that you must analyze the {hardware} out there.

The Royal Dutch Navy has a lifting tank that makes use of two openable metal rings to hook up with their crane, and to the cables hooked up to the car they needed to raise. An elongated O-shaped hyperlink can be the proper answer to have the ability to join these two metallic rings and raise the heavy car.

After importing the design of the metal rings into CAD software program, Ultimaker Software Engineer, Lars de Jongh was then capable of give you the primary preliminary design for the hyperlink they would wish. Lars needed to work with the design necessities.

To start with, the hyperlink wanted to have a flat aspect for a steady 3D print and it wanted to be printed with the layer strains in the identical course because the forces projected on the half. On prime of that, the 3D-printed half and metallic rings’ interacting floor wanted to be as giant as potential to unfold forces evenly.

The Ultimaker Market has tons of of supplies to select from for all types of various wants. Every one in all them has a novel mixture of various properties, which makes it very possible your half will match the set necessities you are attempting to work with.

The fabric wanted for this take a look at wanted to be extraordinarily robust but it surely additionally wanted to have the ability to soak up short-peak forces. They determined to make use of the Addigy® F1030 CF10 from Covestro which is a nylon-based polymer loaded with carbon fiber and might be printed on the Ultimaker S5 with the CC print core.


Utilizing Simulations to Optimize the Design

It takes a lot much less time to 3D print a stable, 2-kilogram hyperlink than it does to provide it with conventional strategies. Nonetheless, the variety of iterations essential to validate the appropriate geometry meant that point was nonetheless an element. That’s why they determined the design ought to be optimized earlier than printing it by utilizing laptop simulations

Covestro labored on this mission to digitally apply the forces on the design utilizing software program that is aware of the precise bodily properties of the carbon fiber nylon materials. By operating simulations, they had been capable of determine the place the design wanted to be adjusted and the place materials may very well be eliminated. This created an optimized design that would raise extra weight, whereas needing much less materials, leading to a quicker manufacturing time with much less value.


Verifying the Simulation

Testing the strength of a 3D printed part for lifting a 12-tonne tank

Earlier than lifting a heavy car like a 12-tonne tank, they wanted to check the printed half’s calculated energy bodily to ensure it might work. They created two completely different designs with two completely different sizes. The primary design was a 1-kilogram hyperlink which they estimated might face up to 12 tonnes. The second weighing roughly 2 kilograms was estimated to have the ability to face up to 38 tonnes.

The Royal Dutch Navy has an on-site industrial tensile tester that is ready to mission as much as a powerful 343 kilonewtons of power on an object. Each the preliminary and optimized designs had been examined for the massive and small variations on this experiment.

The optimized design was capable of face up to a better power whereas weighing a 3rd much less. The distinction between the examined outcomes and the simulated numbers was additionally extraordinarily shut, being only one% off on common. This made this workflow correct and worthwhile in time-to-market and elevated efficiency.


Lifting Two Completely different Autos with 3D Printed Plastic Components

After a number of months of designing, printing, testing, and planning – it was time to lastly take a look at these 3D-printed components in the actual world by lifting navy autos. The components had been taken to the Dutch Military base within the south of the Netherlands the place the thirteenth Mild Rhino Brigade assisted within the testing with their armored restoration car. Their Leopard 2 “Buffalo” has a crane mounted on the entrance and is designed to get well heavy autos akin to vans and battle tanks.

First, the 1-kilo hyperlink was used to raise a navy model of a Mercedes jeep. This car weighs over 2 tonnes. They’d no downside lifting it with the hyperlink and it was simply lifted.

Subsequent, the 2-kilo stable carbon fiber bolstered nylon hyperlink was positioned between the M113 armored car and the Buffalo crane. The metallic rings had been tightened in place and 4 cables had been hooked up from the decrease hook to the car. The crane slowly began to maneuver up, placing the cables and 3D printed half below excessive pressure. The 12-tonne tank slowly started to rise and hovered above the bottom, hanging from a 3D-printed hyperlink! The Buffalo drove round, backward, ahead, and even turning round, and the 3D-printed hyperlink held up completely.


What They Realized From This Take a look at

The mission was an awesome success in not simply producing a powerful 3D printed half that would raise navy autos but it surely was essential to see that CAD simulations have come a great distance, not simply simulating a form, however giving correct predictions taking materials, and even fiber course under consideration. With the ability to depend on such instruments is a significant profit for engineers in addition to the navy basically.

Whereas all components had been printed in correctly maintained rooms and the supplies weren’t uncovered to moisture, there was nonetheless a noticeable distinction between variations printed in a dry warehouse, and components printed with intentionally dried spools of filament in a heated, dry print room. Nylon absorbs moisture and this may end up in weaker prints. That’s why it’s crucial to know supplies’ properties and deal with them accordingly.

If you’re on the lookout for particular supplies for initiatives you might be engaged on, please go to our store the place you possibly can seek for supplies based mostly on energy, warmth resistance, influence resistance, flexibility, meals security and way more.

You’ll be able to choose a number of filters to proceed to slim your search. You can even use the search field on the prime of the location to seek out particular supplies.
