Oops-Ed: TechCrunch Writer Says Consumers Don’t Need 3D Printers

In the early 1980s, Bill Gates was widely known to say “640K is more memory than anyone will ever need on a computer.” This famous quote seems laughable today as your standard home computer, tablet and phone are equipped with gigabytes of memory.
Well, today TechCrunch writer Jon Evans makes a similarly myopic claim about the 3D printer market, “There is no reason for any individual to have a 3D printer in their home.” We are sure Evans would love being compared to Gates, but let’s look more closely at his argument.
3D printing will be a serious threat to manufacturing as we know it. But not at home. That doesn’t make sense. Instead, we’ll have two kinds of communal 3D printer shops.
In high-infrastructure areas, there’ll be a clutch of online providers a la Stratasys (and I expect one of them to be Amazon.com): you’ll pick your 3D design from a huge online menu, send them size information and maybe a few photos from some kind of cunningly designed app, tweak the 3D preview until you’re happy, and they’ll print it out in some vast warehouse full of high-end high-speed 3D printers and ship it to you, possibly that same day.
In low-infrastructure areas, or if you’re a casual hobbyist, or if you have very specific requirements, you’ll head down the road to your nearest local printing facility. Depending on where you are, maybe this is tomorrow’s TechShop, maybe it’s a cluster of converted shipping containers on the outskirts of Uganda each with their own specialties and strengths. They’ll customize your order, render it in the cloud as needed, print it out, and tweak and iterate until it’s done. More expensive but more specific.
While we agree with Evans’ two predictions about online providers and tech shops, we do not agree with his assertion that there won’t be 3D printers in the home. Look at other markets: personal computers, inkjet or laser printers, photo printers, etc. In each of these cases, this technology started out expensive and niche, but eventually moved into the mainstream and enabled new industries to blossom.

Color Blending with Consumer 3D Printers Produces Amazing Results

Consumer 3D printers, like MakerBot and the Cube, cost over $1,300 and can only print in one or two colors. If you want multi-color printing, you need to use a commercial grade 3D printer that costs $20,000 or more.
Well, electrical engineer and hobbyist Richard Home, decided to branch out and design his own method of “color blending”, a technique that turns a basic 3D printer into something much more capable. He started with the open-source RepRap design and developed his own extruder design, which he coined “RichRap.”

As featured in Wired:
Here’s how it works: The RichRap has three extruder motors feeding into one nozzle, or hot end. Each motor spools plastic filament into the hot end where it is melted, then deposited on a build surface. An operator could load a RichRap with red, yellow, and blue plastics and generate green parts by mixing the yellow and blue, or purple by mixing red and blue.

Watch the videos below to see Richard discuss his design and show off some of his color prints.
Cloud Production Coming: Does Every Consumer Need a 3D Printer?

Consumer 3D printers are still costly. The latest models from MakerBot are over $1,700 and a DIY kit still costs $400 or more. Does every consumer need a 3D printer? Not according to Phin Barnes, venture capitalist with First Round Capital.
At AND 1 we had a 3D printer. It was super expensive but it shortened the time from a drawing to a physical object by weeks. The file that drove the printer could also drive the CNC machines in Asia that cut the aluminum molds we used for production.
MakerBot has innovated in the 3D printing space by making the printer cheaper and establishing a marketplace for the digital files that create the physical objects. But for the people who want high quality, durable parts with real utility, will it ever be possible to have a CNC machine in your house for metal objects or an injection mold set up for TPU parts? Maybe, but why can’t I pay Makerbot to make my file in hard plastic or metal? Wouldn’t enough people want this makerbot Prime service to support a CNC machine in Brooklyn? I bet they would – and as the peer-to-peer economy grows, cloud production should grow with it.
Barnes goes on to comment about the different ways that entrepreneurs can solve “logistics problems”.
- Marketplaces: There is great value in coordinating buyers and sellers and removing friction in an existing transactable space. (eBay, Half.com, ETSY, CustomMade, ThreadFlip). This is traditional behavior at web scale.
- Collaborative Consumption: A technology platform that coordinates demand and balances it across distributed capital assets. These platforms unlock a previously latent pool of demand (usually with very efficient unit pricing) and help individual suppliers maximize the value of their assets and time with better utilization rates. (Uber, TaskRabbit)
Both types of companies are solving a logistics problem — removing coordination friction that used to make a transaction impossible — but as this granularity of supply takes hold, the rules of utilization rates and economies of scale will still hold in the world of physical assets. I think this will inspire a third group of companies with logistics at their core: Cloud Production.
In the transition from digital to physical (online to offline) platforms that enable full utilization/rapid amortization of wholly-owned capital assets over a greater base of creators should emerge. Today’s cloud services are maximizing utilization of the physical devices required to store and serve digital goods. Cloud services in the digital space have changed the math of the creator’s business. Instead of budgeting for a certain level of demand — and buying servers to safely cover that projected level of usage, companies/creators can make sure the unit economics work for each unit of demand and architect for infinite scale. Up front costs are dramatically decreased and more ideas come to market.
This same transition should occur around the physical production of goods where economies of scale are powerful. With cloud production niche products can meet global demand and achieve greater scale than ever before. The innovation will be in the coordination and technology required to aggregate individual creativity and produce increasingly specialized, niche products with higher production value and quality.
In summary, physical goods production — enabled by 3D printing — will follow the lead of software-as-a-service and cloud computing to provide goods-on-demand. We are already seeing this trend from 3D printing marketplaces like Shapeways, i.materialise, and Ponoko.

Imagine 3D Printer: Print Frosting, Mashed Potatoes and Much More

Instead of 3D printing with plastic, how about frosting or mashed potatoes? How about other soft materials found around the house?
The Imagine 3D Printer uses special plastic syringes that extrude any kind of soft material. The company wants you to experiment with ideas. Just remember to wash out the syringes afterward.
Imagine 3D Printer is in a class by itself. Imagine is a multi-material machine and thus can make objects with any material that you place in the cartridge. There is an infinite number of materials that you can use. If you can bring it to a soft form first (using a household blender), you can print with it. The sky is the limit.

The Imagine 3D Printer is available for sale and costs $1,995.
Watch the video to see the 3D printer in action.
