That's certainly the goal, Naperlou, athough not there yet. This printer is interesting because it fits in that low-cost enough category that folks might buy one for home, but yet seems to have more of the robust capabilities for designing parts and models on a professional grade. Also, has some pretty impressive backing, including Mitch Kapor who was the original guy behind Lotus 1-2-3, the program that took PC spreadsheets to the mainstream.
Naperlou... this tech will in my mind be one of he must haves for human conquest of the solar system. A few pounds of each rubber, plastic, metal... whatever, and the repair/replacement part inventory becomes much smaller. Plus with a bit more planning the parts being replaced might be recycled into the printing supply stream. And that is very Greenish Star Trek
Formlabs sems to be kicking some Kickstarter you know what. It set a funding goal of $100,000 and a deadline of Oct. 26. The Form 1 has already gotten 942 backers, who have pledged a whopping $1.3 million and change to help this 3D printer see the light of day.
I wonder what they'll do with the overage in donations. 5 minutes research into group funding shows that there are good and bad players in that arena... Kickstarter rates low in accountability and in general... here
On the other hand... I have a ton of ideas that could use a little seed money ; )
Can any one tell me what is the exact difference between rapid prototying machines and a 3D printer? we are already using RPT machines for making new products and the materials which we are using mostly are somos resin or duraform. is 3d printing is advanced than RPT?
I think the biggest difference, from what can see, is the scale and scope. Traditionally, rapid prototyping machines have been huge and highly complex, often run as a bureau within a company with their own staff. Materials choices and production methods are also different and we're talking really expensive--hundreds of thousands of dollars.
In contrast, 3D printing is typically the term used for the lower cost, more office friendly systems that employ a more limited choice of materials and are geared more towards the fast output of designs for validation and optimization, not necessary for production-ready models.
The idea of a 3D printer / rapid prototype machine (the difference is purely semantic in my view) in my home is an exciting development that I'm looking forward to.... but I'm not at all sure that handling liquid resins is something that I want to do in my home office. At work, I've gone with the Stratasys FDM system, which doesn't achieve this level of fine detail but does use real ABS material and is completely clean in operation. We use this machine in the office, and shop out work that requires a messier process. To have a machine in my home, it would have to be clean and not present materials disposal challenges.
@Rick: Your point about the mess and clean up is one that I think many of us overlook in the excitement of seeing these printers get more accessible. That is one area that can be problematic with traditional units and why many are relegated more to the shop floor, not the office. In order for these to take off in the home, the post-printing processes definitely need to be refined so they don't make a mess
Weldon, Formlabs hasn't offered a price yet. They do suggest a price for the materials, at $149/liter. Depending on the solid volume of your part, you might get somewhere between 1 and 50 parts per liter. I suspect the printer will be in the $5K-$10K range, based on my experience as a robotics system mfg. Prices may be lower, given that Kickstarter is funding their IP development so they don't have to recoup those costs.
I haven't donated yet, but intend to. If they do their job right, they're going to crush the 3D printer industry.
The other difference is model strength. A 3D printer only makes a model that looks good. Rapid prototyping systems make parts that are comparable in strength and finish to injection molded parts. Rapid Prototyping systems are typically more expensive because the processes that can provide that strength are limited.
I have even heard of a RP system that laser sinters powdered metal to give you metal parts.
Stereolithography has been around for a long time, and yields some of the prettiest results in 3D printing, and some of the fastest 3D printers are based around it. It is done with a UV cured resin. The original stereolith printers scanned a pool of resin with a laser. More recent ones use a tray of resin with an electronically gated light source below. They are fast because they can do a layer in a few seconds. The resulting models are typically brittle.
I wouldn't recommend using these things in leiu of stock, though. Building parts at a rate of a half millimeter every few seconds means that even a small part takes the better part of an hour to make. They do make great demonstration pieces and "see if it fits" prototypes. And there is a small scale production process that uses 3d printed models to make molds for production parts.
What I would like to see is a fast system that makes parts out of a reusable medium, like wax. Then you could simply feed your failed prototypes back into the system. If it were similar to wax, it could also be used for "lost wax" casting of real parts.
thank u beth for the reply. i have gone through some articles in the internet and seen the same differences. i am really curious to know the "exact difference" between the two. i mean how come one is so expensive and bulky and other one is cheap and handy?? there must be some difference, i mean in tearms of design, accuracy or even functionlity wise.
There are a dozen 3d printers on the market, MakerBot is the latest high volume, sub $2500.00 range. Desk top printers range from $250K for a 4 media 12" by 12" by 9 " machine to the Makerbot machine. This is a welcome entry, the resolution is acceptable at 1 mil. A search of 3D printers returns amazing ranges of hardware, check out Maker Faire. ObJet has the most impressive bang fort the Buck, 4 color, soft molding for outer bumper, under $250K. The field is opening up to be the next Apple quickly.
There are several additive fabrication processes and printer models within those process categories.
STL (stereo lithography) often results in a much higher-resolution part in a weaker material.
It is no competition for laser or electron beam sintering of titanium, or even nylon powders, for part strength.
Its output is single-material/color.
As with all STL printers, models must be designed to facilitate draining and cleaning off the unpolymerized resin.
It is a 'wet' process with post-processing/cleanup/disposal required.
Monomer resins are fairly reactive and often allergenic.
The possible presence of metals as catalysts must be considered.
This product is not a 'killer', since it can only cover a limited sector of the additive fabrication industry.
Don't be drawn in by such exhortations as 'now overhangs can be printed' - this capability has been around in 3D printing processes for a long time.
But it LOOKS capable and well-integrated within its niche.
I would place its output mostly in the 'display model', 'molding form', and 'functional modeling' target areas.
In my prototyping and short production run work I use FDM (fused deposition modeling) parts straight out of the printer with practically no post-processing required. These are around 80% as strong as injection-molded ABS parts, but they don't have the resolution and finish that STL can produce.
@Bobblehead: Thanks for the very informative response. Would the Form1 or any of these lower cost 3D printers be something you might consider investing in for home use or for workshop use? I'd say given your experience with additive manufacturing and 3D printing on the job, you are one of their target customers!
Beth, Charles, there's a LOT more to additive manufacturing processes than I mentioned or know.
Wax model printing for lost-wax investment casting has been used in the jewelry and dental industries for years, but we don't hear much about them, either.
Stereolithography is still in significant usage, to the point that resin suppliers are offering their own resin systems for STL with many and widely varied properties targeting the differing needs of fabricators.
I am not an expert in the diverse additive manufacturing arena, though, and can't offer any numbers to nail down my perceptions.
I think news about STL may have been eclipsed by the 'gee-whiz' factor and vigorous promotion inherent in the Maker community surrounding FDM and the interesting press it can generate, along with the realization that 'every home can have one'.
Perhaps the expiration of some of Scott Crump's FDM-related patents created a feeling that it and similar technologies are now fair commercial game.
But the origins of the Fab@Home and RepRap projects seem to have preceded any 20-year limit on those 1989 patents, so it's not solely a matter of 'locked-up' IP, if at all. I think the Fab@Home effort began with two-part or non-thermal deposition extruders, so they would probably not have fallen under those particular patent strictures.
If I were targeting a model-making capability for casting in larger quantities, then, yes, I'd look very closely at Form1 and some of the DIY STL projects currently out there.
Note that Form1 is not the first Kickstarter STL project, e.g., http://www.kickstarter.com/projects/b9creations/b9creator-a-high-resolution-3d-printer - it would be a candidate, too.
And there are DIY laser sintering projects running now, too ...
A very active arena holding much promise for rapid development and fun, with the added benefit of useful production for many purposes.
Not every home is going to have an additive manufacturing unit, of whatever kind, just as not every home has a snow cone maker.
Again, Bobblehead: Appreciate all your perspective. This is a rapidly growing and changing market. It's true that a lot of the technology has been around and refined over the last two decades and perhaps it's more "news" and interesting from an innovation standpoint to those of us that have not been watching it as closely up until recently. I do think your analogy to the snow cone maker is interesting. I too, don't expect that every home will have a 3D printer (of whatever technology), but increasingly, many more will. Especially those early technology adopters, gadget enthusiasts, hobbyists, and work-at-home engineers who nearly always take part in embracing technology in the early cycles. Definitely an exciting time to be following this category.
Having worked with stereolithography from when it was in its infancy, it is crap compared to todays additive processes. The machines are expensive to maintain, the consumables are expensive and the final output is only suitable for basic visual dimensional purposes as it has poor mechanical properties. Most of the models I worked with had to be recast in rubber molds and other materials in order to test designs as prototypes. I can give you a list of modelmaking companies that invested in the early machines and went broke.
Additive processes allow a wide choice of materials that can have almost the same mechanical properties as injection molded parts. This allows you to make a gear box or a snap fit part in one step. You can even make rubber parts and introduce colors.
There seems to be a lot of confusion about the use of SLA here... SLA is used (heavily still) for form/fit/visulization type models where precision is important. A good example is prototyping parts that will ultimately be made with injection molding. FDM is laughable for that application most of the time-- the precision just isn't there. SLA is perfectly suitable for high precision parts (like snap-fit enclosures, or tight tolerances such as moving buttons, fitting an 'enclosure' to a touch-screen, etc.) where 10/1000ths makes a big difference.
It's also worth noting that this looks *cheap* if you're used to paying for high precision prototypes. Just to have a part made from the usual service outlets can run ~$50-1000 depending on size/volume/complexity/leadtime. Even a "cheap" service (like Shapeways) would cost me ~$200 with a 10 day leadtime to prototype the plastics for a hand-held device. Even if the material costs only saved me 50%, the time savings are considerable when you can do it at your desk. I could see the unit paying for itself in ~15-30 prints depending on who you usually use. (For example, a "next day" turn of a complex part could easily run $1K from a shop that specializes in such things-- even if the material cost was $150, same-day delivery from a printer on my desk would be a huge win and the printer would literally be 'free' from cost savings if I needed to do a few of those every year.)
For small run production, I could also see using an affordable SLA to make a master part and then make silicone molds to produce multiple urethane plastic copies for certain applications. ...and of course there's always just the appeal of being able to thoroughly test multiple iterations of a part before comitting to cutting steel for injection molded parts too. When every test costs $1K you have to think really hard on it, if I can run a test part same-day for $100, I'm sold...
I'm seriously considering getting in on one on Kickstarter now, even though I'm not a "high volume" prototype user. I suspect that it'll be one of those things that once you have the capability in house you'll find more and more uses for it all the time.
It will be interesting to see what happens down the road for these printers as the price of the hardware and material drop. If this became an inexpensive consumer product, I could see it being used as a product delivery method for non-technical items. Just purchase a "use-once" file, download it and out comes your new coffee mug. Or, for that matter, "some assembly required" may include purchasng electronc hardware and inserting in into a infinitely customizable print - drastically reducing shipping costs.
