More than 20,000 readers use this web site each month, viewing more than 50,000 pages to find out about 3D printing, rapid prototyping and additive manufacturing and related products and services. Precisely target your message to that market or any segment of it by placing your ads directly in content that addresses exactly what you're selling.

Our Pay As You Go Ad Program™ uses a payment system based on a combination of cost per click (CPC) and cost per view (CPV). The cost per view of a text ad is just 2 cents and that for a standard banner (468 X 60) is 7 cents. All CPC rates are a flat $1 - and any page has the same rates. You can spend as little or as much as you'd like - buy as much readership as you need. Start, stop and change your ads at any time. You can experiment to improve your ad response and track the performance of different ad versions.

We also offer enhanced service bureau directory listings. Be at the top of the most complete and up to date listings in the world for very little money. Click here to learn more...

Your advertising costs vary each month, depending on whether more or fewer readers see your ad, and whether they take action on it. You only pay for any benefit you receive. You are not paying for copies of magazines that are sitting on a desk unread. When fewer people use the web in summer or over holidays, you pay less. If no one sees your ads or clicks on them - you pay nothing.

That's not likely, though. At present, text ads receive a 0.8% average click-thru rate, and graphics ads about 0.4%. Graphics ads don't pull as well, but they're useful for branding and more strongly publicizing your logo. Text ads also include a small logo of equivalent area of 60 X 60 pixels (approximately 3600 square pixels). We also enlarge and make bold any free directory listings for all our advertisers at no additional charge.

This is a large web-site - literally thousands of pages of up-to-date content. Unlike a search engine where all the traffic passes through a single page, readers find their way into the Worldwide Guide to Rapid Prototyping in many different locations. They use a different complement of our pages to get the specific information they need. Readers looking for equipment will use a different group of pages than those wishing to find a service bureau, for example. You can literally target readers down to specific technologies or tiny market niches.

Let us know what you'd like to sell and we'll prepare a small spreadsheet with several advertising scenarios for you. They'll show pages on the site people looking for that service or product are likely to visit. You can easily see the effects of removing or adding pages by adding or eliminating lines in the spreadsheet scenarios. And better yet, you'll see that you can do effective, targeted advertising for probably less than you spend on your monthly cable TV bill - and you can pretty much blanket the site for a few hundred dollars a month. At most that's just a small fraction of what you'd have to spend on print.

To get your ad program started:

1) Tell us what you want to sell.

We'll send you a spreadsheet showing several different ad scenarios which you can use to decide what your ballpark budget should be. Add or subtract more pages as you wish.

2) Send us approximately 150 characters of ad copy.

The best efficiency and most results are achieved by using text ads. We strongly recommend using them. Remember you've got about 10 seconds to engage a prospect and if you can state a unique selling position quickly - that is key. We also recommend using 2 or 3 variations of your ad copy to track individually and optimize over time.

3) Send us your logo (or let us copy it from your web-site).

We need something that's about the equivalent area of 60 X 60 pixels (3600 sq pixels), or one that we can reduce ourselves to equivalent area. No charge for the service.

4) One month's deposit.

If we haven't done business with you before, we require a deposit based on the estimate for the scenario you choose. You can pay by check (US only), credit card or PayPal. At the end of the first month any over- or underpayment will be applied to the following month's invoice. From then on you'll be invoiced monthly.

Send your information to info@additive3d.com for a speedy reply.

After you send your copy and logo, we'll prepare one or more test pages for you. Once you approve those, your program will be published shortly thereafter. It can take as little as a day to start getting your message out.

We also offer enhanced service bureau directory listings. Be at the top of the most complete and up to date listings in the world for very little money. Space is limited, however. Click here to learn more...
