Serious 3D printing inquiry...

[aurfalien]

I thought to post these outstanding examples of 3D printing.  To me they look cast.  Unsure what sort of printer ScaleProduction uses but whatever it is, there seems to be no texture.

Yesss, that GT40 engine kit is looking superb... https://www.scaleproduction.de/product_info.php?language=de&info=p2336_1969-f-gt40-motor-bausatz.html

Agreed.

As a sort of comparison, that MKIV engine runs ~$50 where as an HRM MKI resin cast engine runs ~$30.

I can clearly see the lines/ layers all over the 3D parts....especially those valve covers. It might be "there" for you, but not even close for me!....

You made that look pretty decent, bud, but I can still see the "layers", which would drive me mental....

This is recommended by spacecraft modelers who use intricate 3D printed detail parts to remove the striations:

Joe, I could not get your link to work. Maybe this one?

Wow wish I'd seen this post before , just spent weeks priming and sanding a 3d printed tank before its natural metal finish

Yeah, that'll work. Thanks mucho, Bill.

Those look pretty darn decent from the photo...

The technology is here; it's just a matter of the equipment used. Reedoak Resin, for example,  laser scans actual equipment and live models wearing uniforms and equipment in order to produce printing files. The same could be done with automotive components; that is, if the 3D producer is willing and financially able to invest in the appropriate equipment.

Some more 3D printed resin items from Reedoak:

1/24 scale

1/35 scale:

1/144 scale:

The printing lines/striations on the Shapeway-produced 3D parts can also be taken care of using the following method from the Reedoak website. Using this method eliminates the possibility of removing fine detail by using abrasives.

Wow, marvelous, thanks Joe.
