Added all the missing small things and completed model this summer. Finally posting updaate.

Fujimi MP4/6 build completed

Added rivets and other minor things for this build in the summer. Used tires with lables from another old model. Finally posting update.

Falling behind in builds of modern cars

I still have quite a bit of work to do on my Tamiya SF70H build. But already I have 3 more kits of modern F1 cars. One red one from 2018 (not pictured) and silver and blue ones from 2019. And my own project of 3D printed blue car from 2018 on top of all.

More assembly steps completed for MP4/6

More progress. Cables are tied up. Steering wheel attached. Brakes assembled and installed. Brake lines routed out to calipers. Rear and front wings assembled. Need to complete number of small items and wheel before Saturday's local context. Will be adding rivets later and some other small details later.

Final assembly started for MP4/6

After engine detailing was finished and rear panels were ready, I could finally mate cockpit, engine and floor. Installed radiator assemblies as well and routed more hoses. Still have to pin down and route quite a few wires.

First test prints done for DB18 project

Received my printer and have done first test prints. My prints look to have lower quality compare to what my friend has produced. I guess I will have to go through my own trial and error process and gain more experience before I could produce better prints. There is also chance that something is wrong with my unit. But I somehow doubt it. It's not a very sophisticated machine.

Layers, even at 50 micron Z resolution, are still visible. I will play with rotation of parts to see if my horizontal placement is the problem. Also details on steering wheel and button box aren't as good as I've expected. I might split those parts into separate batch and print them at 35 micron, the highest resolution my printer is claimed to be capable of.

Biggest hindrance at present is the time it takes to print even small batch of parts. Batch shown on photos took almost 3 and half hours to print. And that's the lower height parts batched together. Software estimates over 15 hours to print floor of this model. While height of the printing area is decent, XY dimensions are quite small. First photo, basically represent whole printer bed filled with parts. And because print time only depends on number of layers (height) or parts, bigger printer bed would help with productivity of printer a lot. Here is where 4K screens could help, when they make their way into consumer grade SLA/DLP printers.

I am running another test with white resin and slightly different settings. Will post results later, if parts come out any different.

3D printed model project started - Dark Blue car from 2018

This is a new project, I have started late last year. Got model ripped out of computer game. I have worked on it for quite a while to make it 3D printable. Plan is to get parts printed and build Dark Blue car from 2018. I like their test livery from that year. So, hope to get a unique model in the end.

Started by splitting parts and making them thicker in Blender. I am still in process of overcoming steep learning curve with 3D model building tools, but got enough understanding and skills to get through with parts for this model.



After I completed parts to my satisfaction and to fit Shapeways' minimal thickness requirements, I finally was able to get a quote from them on how much it will cost me to get all parts printed. I did not like prices I've got quoted. Too much money for 1/20 model. Played with layout of the parts following their recommendations on how to lower print cost with no effect. Either their recommendations are outdated and their new pricing formulas don't care about parts layout any more. Or I don't understand how to use their recommendations.

So, I started to look for alternatives. Apparently modern desktop SLA/DLP 3D printers with around 50 micron XY and down to 20 micron Z axis resolution are coming to under $500 price range now. I've got test print done by another f1m member for me and it looks like I should be able to print parts I have developed on a customer grade desktop printer. It is starting to make more sense to invest into my own SLA/DLP printer, then give almost same amount of money to Shapeways.
