Good
Here I show you a model completely made to scratch. The model is the motor of the ballistic missile V2. Many types of materials have been used as plastics, aluminum, brass, lead and wood among others. I hope you like it.

In another section of the forum I have published the manufacture of the different parts that make up the model. Here I leave the link in case there is someone who has not seen it.

Absolutely beautiful! Just be careful and make sure nobody thinks you are a "terrorist rocket-maker".

Not to steal any thunder from this outstandingly magnificent model but just as an F.Y.I. - someone is offering a digitally printed V-2 motor in 1/35th over on the Shapeways website. Again just sharing information.

Hello partner, thank you very much for the comment and for the information. I did not know that page, there are a lot of variety and curiosities that caught my attention. I have a question, have you acquired something from that page?

Oh yes, so far I have purchased sets of 1/35 spiral car horns to improve under-the-hood vehicle detailing, several SINCGARD radios for my HEMTT cabs and container corner blocks for building my own specialized freight containers.

Currently I am eying a container handling unit (CHU) - my largest purchase so far - to work with my HEMTT LHS vehicles.

The biggest problem with Shapeways is their horrible search engine! It is extremely difficult to search AND FIND a particular item you might be looking for. Often you end up looking through hundreds, if not thousands, of items trying to find the one you are looking for even if you put in the exactly correct title for the item you are looking for.

Hello friend, tell me how is the finishing of the pieces? The surface is rough or thin. You have to go over the pieces a lot? Are there burrs on the edges? I'm sorry for so many questions, but if the finish is good it could be bought. I usually work the scratch a lot and I love it.

The pieces have a nice "tooth" to their surface. Sort of like smooth parts that have had a coat of fine primer. The parts take paint as well as weathering powders and washes easily.

In armor modeling I am not looking for a mirror surface so these parts seem perfect to me.

Given the way they are manufactured, this guarantees no flash, no warpage and no ejector pin marks. The only sanding required seems to be to smooth the attachment point or the gates where the piece might have attached to a larger sprue.


The SINCGARS radio set.
(The radios actually slide in and out of the amplifier base.)

p.s. I even have one digitally printed, 1 to 1 scale part that replaces a broken cup holder in my pickup truck.
