3D Scanning The Audi R8

Nick — Tue, 09 Aug 2022 21:30:27 +0000

Parts for the Audi R8 are not cheap. Seemingly innocuous parts like a plastic duct that sits inside an air diffuser can do quite some harm to the wallet if you pay the price that Audi are asking. I believe their motto for this car is ‘come up with a reasonable price then add a zero to the end…’

Fortunately 3D scanning and printing is here to save the day! The plan was to get the shape of the diffuser 3D scanned to obtain the subtle curvature of the part where the ducts attach. Using this information, the shape of the one of the ducts was formed in Fusion 360 CAD software. The second duct is a mirror of the first so it doesn’t need to be modelled separately.

At this stage, a draft revision of the part has been 3D printed and is ready for test fitment. Once that’s done, any fine tuning to the 3D model will be carried out.

The ducts are barely visible from the rear of the car (note this is not the customer’s car, just an example!)

Although the ducts are almost invisible from the rear of the car, they will be printed in a filament that is suitable for filling, sanding and painting at the customer’s request.

It’s a short and sweet update this week. I’ll post some pictures of the finished part when the customer has them installed.

Bye for now.

Ford Ranger Rear Bumper Prototype

The first prototype part for our offshoot business collaboration, R-Spec, has been designed and 3D printed using the 3D scans we produced a few weeks ago. My business partner Michael has had this Ford Ranger part in mind for quite some time and has already produced a few parts for his Ranger in his garage from fibreglass. As a proof of concept I thought this bumper would be perfect for developing a 3D scanning/modelling/printing workflow for the business.

Ford Rangers are sold all over the world and are a good looking vehicle. Consequently there are many who have taken to modifying them for looks and performance including Michael.

The 3D printing process took around 35 hours total for all seven parts using the super-speed print setting I’ve developed. The individual pieces were then epoxy glued together as they came off the printers.

The fitment was very close to perfect. The length was right on the money leaving a perfect panel gap. The face of the bumper sat around 5mm proud of the rear quarters so we’ll need to take material away in the design. The number plate needs some extra room to fit properly which can be easily fixed by angling the recess slightly higher than it currently sits.

Successful test fit of the Ford Ranger custom rear bumper design prototype.

We’ve decided to add a few additions to the design after seeing it on the vehicle such as a vertical upright section that covers the spare wheel access hole with a removable cover piece. Openings for the number plate lights are also needed.

The next step is to make the changes mentioned to the 3D model and 3D print another prototype to confirm we have something ready for mass-production. Once we’re satisfied that we have a perfectly fitting and quality model we’ll search for a manufacturer, hopefully locally, to produce the finished product. In the meantime the admin part of this business needs working out. Web domains have been locked down as well as Facebook and Instagram profiles.

It’s encouraging to see that this workflow can be successful for a small business and we now have high hopes! We’ll keep you posted on the progress of the part.

Until next week…

More Experiments With A 3D Scanner

Those people who subscribe to our newsletter will have seen a sneak preview last month of what we’ve been up to with the 3D scanner. My old friend Michael and I have been interested in creating our own parts for our cars and so we’ve decided to have a go at building a business from it.

He’s been playing with fibreglass, making parts the old fashioned way which is time consuming, inaccurate and messy, so I suggested that I’d buy a relatively cheap 3D scanner and use it, along with the tools and skills I’ve acquired working as an engineer, to help create the parts. It is then possible to either produce 3D printed molds that maintain accuracy and create parts ourselves or outsource the manufacturing process.

The plan is to get our cars scanned into the computer and use the resultant 3D models as a guide to create our own custom parts. So far we have scanned the Lannix Design BMW E92 and Michael’s Ford Ranger.

The BMW will eventually be used on the racetrack so the plan for it is to produce an air duct for the front guard that vents hot air out of the wheel well. Utilizing computational fluid dynamics (CFD) to assess the expected air flow, we can hopefully come up with something that works efficiently and as intended. The outlet duct will be used in conjunction with inlet ducting in the front bumper, both of which will be 3D printed and tested on the track before going into production.

The Ranger parts are more of a cosmetic upgrade which will set it apart from the thousands of other Rangers on the roads. Modifying them is quite a big scene in countries like Thailand and Malaysia.

The BMW and the Ranger have been chosen for their worldwide popularity. The BMW in particular is one of the few rear-drive cars left where the price of them hasn’t gone crazy like a lot of Australian and Japanese cars that have been traditionally modified among enthusiasts.

We are still in the early stages of creating products ready for market and time has become a far more valuable commodity around here with the arrival of our son Emmet in early May. I have been concentrating more on getting an online store up and running and keeping on top of the design projects for customers and in-house but this is always on my mind! Between changing nappies and trying to spend time with my partner, there never seems to be enough hours in the day. Also, buying a house looks to be in the near future! Damn…

Stay tuned for more about R-Spec in our socials!

Til next week…

Experiments With A 3D Scanner

Nick — Tue, 03 May 2022 21:30:16 +0000

Lannix Design has recently purchased a 3D scanner which we hope will become a useful tool to complement our existing CAD and 3D printing services.

We’ve been working out how to best optimize lighting conditions when scanning to obtain accurate results. So far it seems that dark and featureless surfaces are not ideal! Using brightly coloured masking tape to highlight features seems to help. The marker stickers supplied with the scanner are also very useful.

Post-processing has also proven to be a challenge. The resulting output file from the scanner contains thousands of points of information (a point cloud) and is too much for parametric CAD software to handle without modification. Reducing the file size using Blender software has worked well and has kept all the important detail required for creating custom parts.

Stay tuned for future updates on using the 3D scanner to aid in creating automotive parts.
