Don't forget the super expensive resin you will be purchasing from him too! $350 per liter compared to $40/liter for the lemon curry guy's resin. A year ago, Junior Veloso could have offered these kinds of prices, people would have ate them up and it would be cutting edge poo poo. Anyone who purchases this stuff today is just a sucker.

Yea, that price is right up there with commercial printers. Like the asiga that was just released on saturday. OH YES, 4cm x 3cm x 7.5cm build envelope SIGN ME UP FOR 7 THOUSAND DOLLARS. Mind you they are boasting a pretty impressive 1 micron Z resolution. https://www.asiga.com/store/

I think that it is a combination of: 1- He is trying to recoup his investment too quickly (I don't think anyone disbelieves that he invested quite a bit of his own money into getting his first prototype running, and a huge portion of his time to write his own software). 2- He is misjudging how much his efforts are actually worth on a per unit basis. 3- He is terrible at sourcing parts/does not want to invest the time/energy/capital to source parts for kits 4- He is misjudging what the market is willing to pay for what he has built at this point in time. All in all, there is still hope he'll wake up and come up with a more reasonable pricing scheme, investing the necessary energy to source a proper kit, and discard his current process of (seemingly) 'I should make my money back on the first fifteen units sold and then be pure profit from there'. I however, will not be holding my breath for that to happen.

I tried some googling, didn't see much, is there much thought to 3d printing and cnc finishing? I see the types of tolerances even homebuilt cnc machines can achieve and I think it might be neat to print 99% of the finished product, and swap heads, and get the really nice smoothness people want (where applicable). All the mechanics are there.

All the mechanics are there. How would you calibrate it? Remember when people are talking about home 3d printing, the WORST they are talking about is a .5mm (500 micron) resolution, human hairs can be thicker then that. I can't see any way I could reasonably set a tool or workpiece to .5mm (let alone a tuned ultimakers 20 microns)- When people machine to extreme tolerance they do so relative to there other machined points, not to an arbitrary point -- which is what you'd need to do to set up a 'finished' workpiece and then immediately 'finish' it with CNC machining. Further, even if you could figure out some way to set it up- CNC is limited to 2.5d top down, which means you can't get under overhangs, or really under anything that you could not touch by looking down at the object. Of course at the professional level you can do these sorts of things using laser calibration, and 5 axis CNC robot arms that can happily get up and under things; but those are expensive devices (actually more then one of the high end 3d printers that would just get you the insane resolution from the get go).

Mind you he said his printer would be around 1500 so he could be totally bullshitting everyone. Also jesus man please get someone who knows english to write your marketing material

Just for an apples to oranges comparison, how much is a reel of PLU or ABS by weight? Also - if your lamp matches the resin, whats to stop you buying the lemon curry resin for use in your veloso printer? cakesmith handyman fucked around with this message at 15:33 on Apr 3, 2012 |

Just getting started into the whole world of 3D printing after a friend of mine finished his first 3D Printer and intrigued me. Going to start with a Prusa Mendel and self-source as much as I can. My friend is doing up the printed parts and I've started sourcing the basic nuts and bolts. I have zero... zero experience in this field so this should either be an awesome sense of accomplishment or an utter gong show resulting in missing fingers and a burnt down house.

Yeah, it's also going to have a bunch of subtleties like thermal expansion rate, contraction after cooling, conduction of heat away from the treated volume, etc. etc. - all of which is possible to adjust for, but you won't be able to use a different resin and get good results without a BUNCH of adjustments.

Haha! In an effort to rope in more suckers, Junior Veloso has hidden the number of people who have contributed for each of his rewards. There is no way he is going to make it on the $2k and $4k levels. He needs to get a lot of people buying up the overpriced instructions. The problem is that this technology is so new due to his purge of information and closed source, nobody who would normally just throw money at this kind of stuff really understands it well enough to take the plunge. Everyone who does understand it can figure out that it is way over priced and there are free alternatives. In fact, someone linked me to a crazy awesome looking open source program that uses your GPU to slice stuff super fast last night: ChemShapes https://www.youtube.com/watch?v=efiLcJ5tDvk Obsurveyor fucked around with this message at 11:58 on Apr 5, 2012 |

quote:It was very hard to keep this article at least somewhat positive*, but I think the implied subtext remains. I’m just hoping some builder out there sees the words, “3D printer”, “resin”, and “DLP projector” and heads off to their workshop. This bring up a good point, in that we're all having fun going hahahahah  but really the only problem (so far) is the poor management on the kit/biz end of things.

If it were being run like any sane open hardware design and sensible kickstarter, we could all go back to slobbering his knob like we've been waiting to do. It's a shame, really. e: Although as someone kinda mentioned in those comments too: Veloso's stuff, while still impressive, was WAY moreso a year or so ago.

RepRap Pro is releasing a mendal kit, to go with their huxley kit. Its avaiable to order for those who subscribed to the mailing list. In a day or two it will open to public. http://reprappro.com/Mendel Cost: UK - £499 + £12 P&P = £511 (incl VAT) EU - €599 + €35 P&P = €624 (incl UK VAT) North America - $699US + $70 P&P = $769 Rest of the world - $699US + $80 P&P = $779 Looks like they are going to have a colour expansion for it in the future, adding two more print heads for printing multiple colours or materials.

Man, I've got a hard decision. Everything is coming together, but I'm really trying to make a decision on whether to get spend almost $2k on a Utilmaker or buy a cheaper Thing-O-Matic MakerBot or Replicator. In an effort to save money, because the Euro is trading at a $1.30 rate, do I really need the Laser Cut Parts? Do I really need the NetFabb engine?

My ORD Bot kit is supposed to arrive in the mail today, so I will be assembling it later today. If I can get a camera setup that I like, I may live stream it through the Reprap Google Hangout. I will post more info if I do. Super pumped to finally get started building this thing!

What tools do you have access to? It might be possible to get parts cut locally cheaper from a plan, check waterjetters as well as lasercutters, depending on the parts a bandsaw & pillar drill may suffice. No idea about the netfabb engine.

Don't buy the thing-o-matic. At this point it's just more expensive and less capable than a good prusa kit. The replicator on the other hand, does other cool things. If you're actually considering the ultimaker, you really should get that one. No, you do not really need the NetFabb engine. It is a good G-code generator, but the reprap people know that good g-code is key, and are improving all the time. It's also something that you can upgrade to later if you decide you need it. The only way to skip out of the laser cut parts though is to have them made locally. They are integral to the frame, and they include the build platform as well.
