Topic: New & Cheap 3D Printer?

Hey guys,
I'm mostly new to this whole 3D printer thing, so i could use some help with it.
I've been looking at some of the 3D printers available today, and I found a new model with a affordable price:
ww w . indiegogo . com / projects / craftbot-3d-printer
(Sorry guys, I can't post links :s )
What do you think guys? Should I try it?

I'll never understand the need to spam like that.... It's not like we're unwilling to look at new designs and have conversations with the actual designers.... People are weird.

Re: New & Cheap 3D Printer?

Very true,  I love checking out new stuff.  But the second I see spam I instantly look away and will never even consider buying from them.  Their loss though I like to spend money on this hobby wink

Re: New & Cheap 3D Printer?

IMO, a much better investment:

https://www.kickstarter.com/projects/co … 3d-printer

Cheaper, bigger, uses better parts. At $300, the elctronics, hotend, and extruded aluminum are worth the cost.

Re: New & Cheap 3D Printer?

That CobbleBot looks like the bee's knees! I think I'll wait until they have the heated bed feature, though. As it looks now, seems like the bed is solid and wouldn't require any calibrations. That X belt, however, kinda looks flimsy.

but for 15x15x15 printing at $300 my mouth is watering....

Re: New & Cheap 3D Printer?

I almost dropped the money on it this week. Compared to other crowd-funded printers, this is a very low risk investment. Like I said, the components being used are standard RAMPS and LCD, good sized steppers, extruded aluminum, and an all-metal hotend (wish he would keep the hex one instead of redesigning one). Even if the final printer delivered ends up being a let-down, the parts alone recapture most of your investment. Thats why I consider it low risk. Since he is shooting for enough volume to make molded parts, there is a decent chance the final product will be at least the same quality as most other crowd-funded printers (read: it will work, but there may be some design flaws that users will find solutions to on their own just like, oh say, Solidoodle, Printrbot, Robo3D, Qu-BD).

Now, realistically this build volume has a major downside not being currently addressed: Heated bed. He promises it at $1M goal. But the big problem is logistics. The only off-the-shelf currently available is silicone heaters. Once you get beyond 8x8" sizes, the cost is usually pretty high. But beyond that, is powering them. The wattage/amperage of a 16x16 silicone heater is so high, you would burn out the traces on the RAMPS. So if your going to control it, you should use a SSR to power the heater. This is all regurgitated info from previous discussions.

Still, for $300 that build volume for PLA is very tempting. And it would be easy to hack it so that you could make a removable 8x8 PCB heater + glass for ABS (just place it above the standard bed and change homing offset).

I would get this, but I dont want to wait. I have decided that forking over $400 after the crowd-funding is over for quick delivery is better for me.

Re: New & Cheap 3D Printer?

The Cobblebot actually looks pretty nice - I may end up picking one up for my brother.

I wonder if he hits the stretch goal, if it will be a separate power source for the heated print bed? I can't imagine another way to do it and stay profitable, but it's *very* intriguing.

Edit: Forgot to say, also makes me think of GLADOS for some reason ;-)

Cobblebot is basically guaranteed to fail at that price. I wish you could pledge against Kickstarters. If the KS can't deliver on time, you get twice your money back. If they do, they get to keep your pledge and you get nothing. Call it the "haters gonna hate" reward tier. That'd be fun.

A separate power source would not be needed, "30A" (i put it in quotes because the power supply is almost certainly an overrated Chinese knockoff waiting to burn your house down) is plenty for printer and bed.

Uh, say what?

He's selling for about 110% of BOM costs, once you take out the 10% for KS/AP. He's basically guaranteed to either be very, very late on deliveries while he sells preorders at a higher price post-KS (see RigidBot, QU-BD) or fail completely.

Or he'll take the money and move to an island in the Caribbean. Honestly I'm surprised more folks don't commit outright fraud on Kickstarter, there's zero accountability.

I agree. But the electronics at volume are less than $75. Getting the parts molded reduces plastic costs greatly (basing off labor, not material). The only expensive thing is the extruded aluminum, which can be alot cheaper in bulk. But I agree that when the dust settles, the KS delivered printers will end up a wash after the effort to deliver. And that is why I think its a low risk. There have been very few KS campaigns that never delivered. This could be the first massive one. But the way I look at it is, most likely what will happen is this guy will buy the parts and quickly assemble. If the reliability of this mass assembly does not come out right, you end up with 75% of your money in decent parts you can use to make a different printer.

But arguing if this KS campaign will end up with people getting ripped off is a different discussion which belongs to any crowd-funded campaign.

Re: New & Cheap 3D Printer?

Lets go crazy and call the electronics $60. (remember, this is a RAMPS, MEGA, 4x A4988s AND a LCD)

Electronics: $60
PSU: $25 (its a 30 amp, and power supplies are expensive to ship. I pay about $6/kg for air freight)
Steppers: $35 (5x NEMA17s)
Hotend: $40
Extrusion (20ft@ $2/ft): $40
Bearings, belts, pulleys, fasteners: $50

That's $250 right there, and I haven't accounted for either a print farm or injection molds. Remember, he only gets $270 after KS/AP fees. I would say that if the backers get anything, it'll only be after they're subsidized by more expensive kits sold post-KS. That's what happened to Rigidbot and Filabot, just to name a few. Last I hear Filabot was still using money from website sales to fulfill Kickstarter orders, though he may have caught up by now.

Yes. Those prices are what you can buy them at per piece. In volume of 2000 pieces, you can knock that down easily by 30% or more.

QU-BD did the One-up for $200 with pretty much the same equipment and their structure was loaded due to having in-house laser equipment (US labor costs, not overseas) and they delivered.

Although I am concerned about their decision to design an all-metal in-house instead of using the hexagon hotend. The purchased hotend was one of the attractions.

Re: New & Cheap 3D Printer?

Those prices were definitely already discounted, and you aren't accounting for shipping or import tax. Also I don't think Chinese pricing works like you think it does. Have you tried sourcing from China? The power supplies I buy are only 5% cheaper at qty500 compared to qty1. When labor is cheap, you don't get as much of a bulk discount because labor to handle a single product is pennies, so the qty1 price is already very low. The hexagon hotend is $50 (before shipping/import duties), so I've already knocked 20% off the price in the above BOM. This guy's a lawyer, not an engineer or a machinist - so he'll be farming out the majority of the manufacturing. It's gonna be bad. Real bad. Again, look at Rigidbot - charged $45 more, smaller build volume, and they're still struggling to get them out the door (months behind schedule).

QU-BD used MDF in place of extrusions (save $30), a much smaller power supply (save $15), a much cheaper set of electronics (save $30), a cheaper, PEEK-based hotend (save $15), one less stepper (save $7), and smaller bed, shorter belts, fewer pulleys, no printed parts, and shorter/smaller bearings/rods (save $23). Total savings of $120, brings their BOM to around $130. And they're still struggling to stay afloat.

I've been sourcing electronics and motors from China in bulk for 7 years now. I like to think I have a decent handle on pricing.

Also, please show me where you can get that extrusion at $2/ft in single unit quantities. I will buy a pallet load. It's $4/ft here below so I've already discounted it a *LOT* - 50% off retail. I just double checked and he's using closer to 30ft of extrusion, not 20 ft so even if he's getting the stuff for $1.25/ft which is basically the cost of raw 6061, he's still spending $40 on it.

Re: New & Cheap 3D Printer?

Guys why would you need a 30A power supply? It's less safe, but an AC power bed is the way to go with bigger build platforms. There are still many problems, but I don't think the major one is PSU. Ground the bed, and use GFCI outlets, and the danger is not so big.


I also however agree that this is hopeless for KS and generally Elmoret's criticisms are accurate.

Tim,
From your Grainger link, isn't that about $4.60 / ft?

Also, it's even cheaper at Inventables, albeit a 20 x 20mm, not 1"...

Yup, my mistake. I'll go back and edit. For some reason I thought that was a 4ft section, maybe I looked at the shipping weight.

Either way, I've never seen $2/ft.

Re: New & Cheap 3D Printer?

Also, that cantilever thing is not an ideal mechanical design. Makerslide aside, it's going to flap around all over the place when it gets moving out front: why not just have the front part of the frame at the front of the printer and support it properly? To save 500mm extrusion maybe? Sigh.

Given I see little value in the design (maybe you disagree, that's OK) - assuming everything goes as well as it can for the project, from my perspective the proposition looks like $300 to receive $250 worth of parts (that I could get anywhere else) in 18 months time. I'm not sure I'm on board...
