Topic: Car emblem scanning or creation

Hey everyone,

I have some old emblems for a kit car ( I own the trademarks) and I am trying to figure what the best option is to get them into a printable format. I have been looking at various 3d scanners out there and I think they would do the job, but to buy a scanner for 4 or 5 emblems just seems like a waste. I have no idea how to recreate these with any program such as sketchup . They are about 3.5in round and 1/4 in in width. I think they would be really easy to create for someone who know what they are doing.

Anyone know of a service that is inexpensive to get this done?

Thanks

Post a pic or two. If they are just 2D essentially, a scan of the image, running it through an outline mask in inkscape, and extruding the image would be enough.   But more can be said when you post an image of what you're looking for.

I you wait, I will try to cut out.  Will re-do as I did that in about two minutes, and could probably do better.

I am going to by a new laptop . This one is about to crash on me. Battery warning light just came on, among other things.  4 years of abuse is more then enough to ask for . Here is what I did.....

That looks good.  Here is another one, round.  The double f's in center will be see through.  Try to print in two colors.  On this slice at 3mm change filament on layer 4 or 5 to another color.  If you re-size, you should look at the g-code view to determine when to change filament.   Check out that software when you have time.  I used netfabb studio free to cut out the model.

Re: Car emblem scanning or creation

Well, I got it in and got it cleaned up some and it slices ok but it still looks like it will print with some gaps inside the letters. Not sure what's going on there.

I have a question. In Sketchup how would I fill in everything between the letters and center logo. I want no empty area in the middle and just a the letters raised a bit, but flush with the sides.

Also are there any tutorials out there that will show me what you did to create it?

Thanks

I am not sure my ways are the best ways.

If you mean something like the attached, to add a base basically I grouped the logo, drew a square under it, pulled it up, intersected it and trimmed the excess.

To do the 2d to 3d I used gimp to crop to a circle, make it high contrast black and white with a transparent background and invert it. Then inkscape to trace the bitmap, blender to extrude it, netfab basic to repair it, meshlab to simplify it and sketchup to clean it.

The inkscape and blender work is very well documented on the web and so are the other tools.

I think a few folks are moving on from sketchup for this kind of work but I have been using it and gimp forever so I am kind of stuck in my ways.

Re: Car emblem scanning or creation

Thanks for all your help. I think that last file you posted has so issues. I load it into Repetier and slice it and it shows that it needs 29.6mm of filament and was 48 layers. I tried to print it and it was printing a pattern that was nothing like the emblem hahaha

ALWAYS check the log. It needs to be repaired.

<Slic3r> The model has overlapping or self-intersecting facets. I tried to repair it, however you might want to check the results or repair the input file and retry.

That message spells doom. The preview in the G-Code editor would also let you know there is a problem. I only uploaded it as a demo of adding the base.

In the interest of eating my own dog food, and perhaps paying you back some for the shoddy model I foisted upon you and that you unwittingly accepted, I have printed it myself, albeit at 50%. It is still nowhere near right and does indeed exhibit the problems I saw at first, and then some, yet I continue to foist it. I may try a section plane next so I can start with something cleaner.

Re: Car emblem scanning or creation

smile You do not have to go through that. You have already helped more then enough. I was just really curious why it was printing a pattern that looked entirely different then what the model looked like. Im still very new to all of this so im sorry if I might have sounded ignorant .

Thanks for all your help

Re: Car emblem scanning or creation

So check it out. My printer started being a jerk and a part of the emblem started lifting up but other then the that, the A not having a hole on the bottom, and the overall size being about 1/2 inch to big I think it came out really good. I cant thank you enough for your help.

Re: Car emblem scanning or creation

To get a more precise size add a dimension inside the group in sketchup and scale it. You can enter the exact scale you want using the keyboard or fuss with it until you get it close with the mouse. You can manually calculate the scale to 3 or more decimal places and enter that. Or you might just scale it in RH.

As for the lifting, proceed at your own risk, but, I have found that I have to lightly treat the bed with "ABS juice" every now and then or nothing will stick ever. Afterwards things may stick too well and require a tool to remove the part so I like to use a pair of pliers to free the part because using a knife eventually it will slip and trash the Kapton.

Re: Car emblem scanning or creation

Your are speaking foreign to me hahaha.

I am going to start reading up on everything that these programs do. I have 4 of these emblems total I need to get done and a host of other little things. Im sure it all is beyond me and I will end up paying someone to do it but I will still read up on it haha

In addition to their 123D CAD software, Autodesk also has Catch, an online service that turns photos into 3D drawings you can print.

Re: Car emblem scanning or creation

It looks like for what you are trying to do, replicate a few car emblems you already have, you might just do it the old fashioned way by creating silicone molds and casting resin copies. Before you go and research this option be forewarned, once you hear the tap plastics theme song it will never leave your head.
