Cosmic Modelz

On August 3, 2006, The Wall Street Journal published an article titled New Copiers Create 3D Plastic Models on Demand. The story introduced 3D printers to many readers and cited recent developments and applications of 3D printing. Also, it revealed that SolidWorks is launching a new business called Cosmic Modelz in the coming weeks. Cosmic Modelz will permit kids—or anyone—to use the company’s Cosmic Blobs software to create custom action figures. This easy-to-use software sells for $40 and is targeted at kids. Using a new website operated by Z Corp., the Cosmic Blobs models will be sent to Z Corp. for production on one of its color 3D printers. The cost per model: $25 to $50. 

If you go to http://www.cosmicmodelz.com/, you will see a “Coming Soon” page (as of today) that introduces the visitor to the new service. The page shows examples of the kinds of figures that are possible.

If SolidWorks and Z Corp. follow through with the plan, it will be the first serious attempt to “commercialize” the use of 3D printers for the mass home market. Pricing is aggressive, so I would expect that many people will give it a try. When they see the model quality from the latest generation machines from Z Corp., they will undoubtedly show and tell their neighbors and friends. 

Nothing quite like this has been available, so its novelty could lead to something big. If even a tiny fraction of the kids with access to computers choose to have a model produced, it could generate millions of dollars of revenue.

I applaud SolidWorks and Z Corp. for their creativity and originality. I will be among the first in line to give it a try. And that line will likely grow long as the word gets out.

Sixty Machines at Work

On July 27, I visited the Paid Parts group at Stratasys (Eden Prairie, Minnesota). Paid Parts is a part-making business unit that includes RedEye RPM and Xpress3D. The company is running 60 fused deposition modeling (FDM) and PolyJet systems around the clock to meet the current demand. When I was there, most of them were running. Stratasys moved Paid Parts into one of four buildings that the company now occupies. Space adjacent to the 60 machines is open and ready for expansion.

Seeing 60 machines in a single room was impressive, and so was the few number of people needed to operate them. Only five individuals load new jobs and remove parts from the machines. These people also interface with the customers and manage the projects each step of the way. The post processing room is surprisingly small and simple, consisting of only two tanks for automatically removing the support material.

The company is attracting far more “rapid manufacturing” jobs than anyone at the company had envisioned. Rapid manufacturing is the use of additive fabrication to make series production parts rather than models or prototype parts. As a result, Stratasys is now targeting this market opportunity. One customer that produces specialized parts for cameras has ordered 1,750 PC/ABS parts to date and expects to order many more. The goal at the company is to eliminate all tooling. Another company has ordered 4,800 polycarbonate parts for a hand-held medical device that surgeons use for heart patients. Yet another rapid manufacturing job is for the U.S. military. It has ordered 400 parts in PC/ABS that are being used for a flashlight that mounts to an M16.

For each of the three examples, typical delivery is 50-200 sets of parts per week. Volumes are relatively low, so the production of tooling is an expensive proposition. All of the parts are relatively small and surface finish is not critical. As a result, it is feasible to produce these parts much faster and less expensively with additive processes, compared to the alternative of making molds and using injection molding.
