Advice on Mould making small item(car badge)

Unless you plan on going into business selling these badges (and have a reasonable sized market to sell to), you won't be able to justify the cost of a mould IMO. Even doing an additive process (DMLS, FDM, etc.), just generating the CAD file + the fabrication cost will not be much less than 300 quid (unless you already have access to a CAD system and you pay yourself $0/hour ) -- and then there must be some finishing costs.

What is the material and finish? Metal or Plastic?

 

Laser scan the original part + 3D print. Be sure to sand and impregnate the finished part for added strength.

 

These guys might be worth a look; Casting & Molding Supplies - Find Liquid Rubber & Resin Casting at Micro Mark

(Although, I'm not sure how you can do it without an original to work from?)

FWIW, the same guys are also now selling a 'DIY' 3D printer too; 3D Printer Kit

No affiliation, just a happy customer BTW.

Depending on what the badge looks like it might be hand-sculpted from clay and cast in metal using lost wax.

How about a picture?

 

Need to see pics but for this type of item I normally would do a silicone mold and then cast the piece in a metal based resin.

I get all my supplies form Reynolds Advanced Materials.

BUT....

As pointed out it is a very time intensive, expensive process. You have to do the math but it might still be cheaper just to purchase one. Ready made and be done with it. Also, unless you find a 3d printer service that specializes in metals your average 3d printed part doesn't hold up well in a long term environment with UV exposure.

 

That looks like it could be fabricated easily. The typefaces look like something commonly used. Anyone with a graphic software program could make a life size pattern.

 

Maybe you could ask Fchatter "Magnum" to make one for you. He does key chains that look great.
