3D printing - What a difference a setting makes...

Since the first excursion into 3D printing left me with a bit of mixed feelings, I haven't been doing a lot with my Anycubic Photon 3D printer lately.

When I was drawing up a part for the Aston Martin DBS I'm currently working on I thought I might as well give the Motegi wheel for the Ferrari F458 GT2 (my first project on the Anycubic) another go.
As I was convinced that the part I drew in OnShape shouldn't pose a problem for it.

I adapted the 3D model a bit to prevent the resin liquid from pooling up in smaller areas hoping that this would fix the issue of residue clogging the said areas as happened with my first attempt.

I also played around with the settings, giving the respective layers a longer exposure time.
Where I used the blue framed settings for the first print, I opted for the red framed one this time.


The values are taken from a public document available on the internet where people can contribute their settings.

And boy did that work.
Okay. Maybe it was a combination of room temperature and exposure time. I'm not sure. But I'll definitely be using these setting again for future prints.

I'm completely astonished at how good this print turned out. No flash, no residue, just a nearly perfect wheel. Below are pictures of the first attempt (left) and the second attempt (right)


As can be seen on the right image, the spokes are now open and not the tiniest bit of residue in sight. I'm going to print this wheel again, this time with the spokes closed again.
The other thing I'm going to change is the wheel nut. I'll be printing the wheel without the nut and will print the nut separately. I'm going to redesign the nut slightly to give it some more detail. This will come at the sacrifice of realism, but I think that won't be such a drama.

All this gives me confidence to try and print some more parts in the near future.

Citroën Xsara WRC - Francois Duval, ADAC Rallye Deutschland 2007 (part 5)

As promised in the previous part in this update I'll show what I changed on the roll cage. The roll cage as included in the kit is far from complete. When looking at on-board footage and reference images found on the internet the roll cage needs some extra tubing added.  Over the years the roll cage of the Xsara WRC has had several variants as I've noticed studying my reference images. Which isn't that strange as the crash test and safety regulations have changed over the years.  The reference images I have of the specific chassis (#28) which Duval raced during the 2007 ADAC Rallye Deutschland are sadly inconclusive about which version of the roll cage was fitted. Which means that the adaptations I made are at best a good "guesstimate"... As long as it looks and feels right, it is right I guess... I used Evergreen styrene rod of 1.6 mm in diameter for the added sections for the rollcage.  The added sections are highlighted in the images below. Another section I...

Benetton Ford B190B, F1 season 1991 (part 6)

After preparing all the sub assemblies and parts I gave them a good wash with lukewarm water with some dish washing soap. While the parts were drying I decanted Tamiya surface primer (white and grey) into some paint jars. All the parts received a grey primer coat to check for blemishes or spots that need to be reworked. After everything is checked the wings and body will be primed with the white surface primer. After the grey primer, this is how everything looks. Apart from the front wings and the rear wing, everything looks ready for a splash of color. The front wings need some extra work filling and sanding to get rid of the ejector pin marks. The ejector pin marks on the rear wing are hardly visible anymore. Only a few short shot spots on the back of the rear wing need some attention. After sanding, the front wings, rear wing and the body got a coat of white primer in preparation for the color. In the meantime I already painted the suspension, cockpit and engine/g...

Benetton Ford B190B, F1 season 1991 (part 5)

Well. I can hardly believe how long I've been silent here on this blog. Not counting the two show reports I posted earlier this week, the last posting here being from November 2021... But, since I went from a 5 to a 4 day work week at the beginning of this year, there is finally some more spare time to spend. Oh, and a good cleaning of the modelling "cave" did also help in motivating me to dive into the cellar and do some building again. To start a (fingers crossed) longer stint of modelling activities, I decided to (finally) continue with this particular kit. It's been lying around for almost 10 years, so you can say it's desperately in need of some attention. Luckily all parts are still accounted for as I had the parts nicely packed away (for a change). Upon inspecting my work I couldn't quite look past a few things that weren't so neatly done. Especially the engine/gearbox and rear wing assemblies were a bit wanting. Also, upon cross-checking ...
