Interesting point, Rogue Moon, about 3D printing, and this type of machine, stimulating a lot more small-scale, at-home businesses. That sounds a lot like what the inventor himself said.

OK, I saw it now. Nope, I swear I don't remember anything like that. Think it was must have been just after my time. Looks like fun!

You have to see the reply from  YALC, dated   6/7/2013 - 3:09:02 PM (just a bit below) .  YALC posted the link to the original machine, exactly as I remember it as 5 year old boy!  From that link, hit "Vintage-Mold-A-Rama" in the left margin.  Thank You, YALC !

Jim, that must have been a regional thing, maybe also a different era. I don't remember anything like that at the San Francisco Zoo in the 50s or 60s.

Right, Droid - This IS the key issue being missed:  CNC cutting, even in low cost aluminum, is beyond the budget of most DIY'ers.  ProtoMold.com is one of the best, fastest, and least expensive On-Line CNC shops today.  Just this week, a little ~2" custom designed plastic enclosure was quoted at $3,500 for the bottom, and $2,800 for the mating half.  About $6,000 for a tiny housing set.  Cheap for a corporate entity, but beyond reach for the hobbyist.

I remember the Mold-A-Rama machines from the Oklahoma City Zoo from my youth, and that was only the 1990s.  The Zoo had the operator remove the machines a couple years ago.  See http://www.replicationdevices.com/about_us.html

Thanks for the link, Steve. Some readers like to build their own and some would prefer to buy one, as we've seen in some Gadget Freak columns.

Great commercial and 1 minute long instead of the current 15 seconds!  I had friends who had Creeple People molds. Feet, hands, a head you fold over and hold with a neck ring onto a pencil to make a doll (of sorts).  We used to fill syringes with denatured alcohol and shoot through a candle to flame thrower them.

(ahem) Maybe I just dreamed that last part :-)

Google "kenner mold master" and you'll find photos of the product that don't do it justice.

Like the old Vac-u-forms, a toy that could really raise a blister, toys of the 60's were scaled down industrial processes instead of the nerfballs we have today.

Lego Mindstorms and Vex Robotics are about the only useful toys out there today. Unfortunately after the industrial controls I used to do, it has too few I/O's to interest me. Vex has enough I/O for my interest, just too pricey for my budget.

BrainiacV – I don't remember that Kenner toy; I wish I had one!  I did have Mattel's 'Thing-Maker' & Creepy-Crawlers;  and then later, the Incredible-Edibles version of the same.  Both were poured in a cavity only (no core) and baked like an Easy-bake oven.

Wow, what a blast from the past.  And what a testimony to the difference between the Obama administration and the Johnson administration. How times have changed!

Isn't it funny that these micro-industrial processes were commonly showcased at the Zoo, of all places-?  That's where my memory pulled that ancient recollection, and now you have the same memory -- I'm now curious if it was the same Zoo-?  For me, it was the Detroit Zoo, circa 1965.

As the 3D printing and overall additive manufacturing ecosystem grows, standards and guidelines from standards bodies and government organizations are increasing. Multiple players with multiple needs are also driving the role of 3DP and AM as enabling technologies for distributed manufacturing.
A growing though not-so-obvious role for 3D printing, 4D printing, and overall additive manufacturing is their use in fabricating new materials and enabling new or improved manufacturing and assembly processes. Individual engineers, OEMs, university labs, and others are reinventing the technology to suit their own needs.
For vehicles to meet the 2025 Corporate Average Fuel Economy (CAFE) standards, three things must happen: customers must look beyond the data sheet and engage materials supplier earlier, and new integrated multi-materials are needed to make step-change improvements.
3D printing, 4D printing, and various types of additive manufacturing (AM) will get even bigger in 2015. We're not talking about consumer use, which gets most of the attention, but processes and technologies that will affect how design engineers design products and how manufacturing engineers make them. For now, the biggest industries are still aerospace and medical, while automotive and architecture continue to grow.
More and more -- that's what we'll see from plastics and composites in 2015, more types of plastics and more ways they can be used. Two of the fastest-growing uses will be automotive parts, plus medical implants and devices. New types of plastics will include biodegradable materials, plastics that can be easily recycled, and some that do both.
