A Bid To Take 3D Printing Mainstream

daid303 Re:Yet Another Crap Extruder (143 comments)

http://daid.eu/~daid/IMG_20130...
Printed on a "crap extruder" printer, without problems.

You're generalizing. Just because it does not work for metal does not mean it does not work for plastics. Plastics have a very different thermal conductivity.

Heated chambers are not patented. A specific implementation of the heated chamber is patented.

(Do have to agree that they concentrate too much on the machine. The machine is hardly the problem)

3D Printing: Have You Taken the Plunge Yet? Planning To?

daid303 Re:Hype (251 comments)

I know a guy how consistently prints watertight cups.

PLA layers fuse very well. ABS is harder, which is why everyone is switching towards PLA.

More expensive is usually better. But, 20k machines from 3D systems are getting the same quality as 2k hobby machines.

3D Printing: Have You Taken the Plunge Yet? Planning To?

daid303 Re:Which CAD software? (251 comments)

For part design I've switched to DesignSpark Mechanical. It's not really 100% free. But I really like the interface and how stuff works. It's a bit like SketchUp on steroids, but then made for CAD.

3D Printing: Have You Taken the Plunge Yet? Planning To?

daid303 Re:3D printing (251 comments)

Dropped my Ultimaker from my bicycle. Twice. Still prints without any adjustments. Most RepRap kits are not that sturdy. You get what you pay for in this case.

Standardization in 3D printing is STL right now. And a large standard commission is working on the next version (AMF).

Software, oh, did I mention this yet. 3D model to toolpath. OpenSource. A few options available. My own, Cura, started as a hobby project, after 6 months I got hired by Ultimaker to make it awesome. Which it is these days. Still OpenSource, now just more awesome.

3D model creation? Blender. 100% FOSS. OpenSCAD, 100% geeky. DesignsparkMechanical, only partially free, but 100% awesome.

Thanks for all the FUD.

Ultimaker Debuts Ultimaker 2 3D Printer With Open Source Cura Software

daid303 Reporting from Ultimaker. So much mis-information! (53 comments)

Ok, there are a few major things WRONG in this article.

First of. Cura. Cura is my project, I started development 2 years ago. I started in my free time, and after a few months of development Ultimaker hired me to continue development. As every user was switching towards it. It has been open source, free, and released for 2 years now. (It is a perfect success story for Open Source and I think Slashdot totally missed the opportunity here to properly see this)
Thanks to Ultimaker Cura has seen a HUGE development boost and really became awesome for Ultimaker AND RepRap users.

Next, WiFi is not in the machine out of the box. It is an add-on.

The UM2 is a professional looking version of our already very successful Ultimaker-Original kit. It has great printing quality for a nice price tag. Yes, you can do cheaper, but not if you want the same print quality. If you want cheaper then the UM2, buy the UM-Original kit.

Breaking Up With MakerBot

daid303 Re:Learning to fly (185 comments)

You are so right on this one. Makerbot is all marketing all the way down. Their machine isn't special (hotend+extruder copied from the UP!, Z platform copied and slightly improved from Ultimaker). Their move away from OpenSource also hasn't done much good to the "hacker crowd".

But, reporting from Ultimaker here (you know, the 15 man company from the Netherlands that sells 3D printers). Dual extrusion is possible in a good way. We're working out the kinks and don't think it's ready to mass sell as Makerbot does it now. But we are getting towards Ultimaker quality.

MakerBot Merging With Stratasys

daid303 Re:So? (65 comments)

Reporting from Ultimaker. You know, the real OpenSource 3D printer, that actually DOES do open-source software development.

Our printer hit the market 2 year ago. It's still top of the line. Sure they are cheaper options, and even a Chinese copy. You know what, they don't get the same quality and speed that we do.
The Cube is noisy, slow, prints in low res (as it's not allowed to compete with the expensive Dimension 150) getting one of these will more likely disappoint you in the capabilities of 3D printing then providing you with something useful.

Stratasys buying Makerbot is surely interesting. As they are paying about 20k for each printer sold so far. So they are not paying for the current market, they must be paying for the marketing, and thingiverse. People have been pulling models off thingiverse already because of this deal.

As on the Ultimaker open-source side. We just released our new version of our Open Source software solution Cura. Which is all AGPL, the GUI and the engine. Everything is usable on RepRap machines, and you can follow development as it happens. No secrets here.

What's Holding Back 3-D Printing

daid303 Re:Extremely expensive. (348 comments)

PLA is not water soluble (That's PVA). And works outdoor fine, it just has a low glass-transition temperature where it won't work very well in high heat areas.

What's Holding Back 3-D Printing

daid303 Re:Cost of the raw materials (348 comments)

I'm sad to hear that you own a Makerbot. I got an Ultimaker a year ago. And now I'm working at Ultimaker for a few months on software developement. We leave Ultimakers unattended a lot. I've added extra safety features in the RepRap firmware for this reason. We've done 100+ hour successful prints on our larger sized printers (up to 52cm). And we're working on improving the safety on our ready-build printers. But I have no fear in leaving our printers run unattended right now.

Makerbot does little innovation and mostly marketing. PLA printing? Guess who started that. The Makerbot extruder? copy of the UP! extruder. Gantry system? Ultimaker started with that. 3D scanner? Makerbot already did that in 2010 but they erased most traces of it.

As for the filament price. I know a raw roll of 0.75kg PLA costs us about 20 euros in bulk. The producer of the filament pays 4-5 euro's for the raw pallets, but has done a 20k investment for the extruder, and numerous hours tweaking the production process. So the producer needs to sell 1333 rolls before breaking even at the current price. The reseller also makes some profit for splitting the bulk into single rolls and shipping them. Add some tax and you are at the 30 euro price (which is 40 dollar, your factor is slightly off because I mixed euros with dollars)

What's Holding Back 3-D Printing

daid303 Re:Not enough publicity (348 comments)

In pure solid modeling FOSS we have FreeCAD and OpenSCAD.

Blender has some help tools for solid modeling (the "select none-manifold edges" [ctrl]+[shift]+[alt]+[m] really helps, as well as the remove duplicate vertexes with a range setting)

What's Holding Back 3-D Printing

daid303 Re:Nonsense (348 comments)

Board gamers love 3D printers for custom play pieces.
Lego builders like them for custom bits.
Robot builders like them for getting that missing bracket/piece now instead of in 2 weeks for 10x the money.
Architects like them for scale models.
Product developers like them for prototypes.
Artists like them to produce new and interesting art.

And I like them, because I'm printing an Desert Eagle for an arcade cabinet.

(Actually printing a working gun that does not have the risk to blow up in your face will be proven to be quite difficult)

What's Holding Back 3-D Printing

daid303 Re:Cost of the raw materials (348 comments)

You sir. Sorry for the word. Are an idiot. And have no idea what you are talking about.

A kg of filament is a LOT of filament. Plastic is light and objects are printed partially hollow. I do expect prices to drop a bit in a few years, as the raw plastics pellets costs about 4-5 euro per kg. (asking for 40kg per dollar is just sticking your head up your ass and asking for a pony)

What's Holding Back 3-D Printing

daid303 Re:I've been designing/building a 3D printer for (348 comments)

I made Marlin Arduino 1.xx compatible a year ago. And everything you say is RepRap related (who do a bad job at documentation), not 3D printing in general. You can buy an Ultimaker kit and be printing within a day. But you went the DIY route and are now surprised that you need to DIY stuff...

The 3D Un-Printer

daid303 Re:As someone who is a large part of the community (91 comments)

Not sure how you could build a $200 3D printer. I did a BOM for my TITAN 3D printer. And I'm on about 300 euros. Just steppers and steppermotor drivers sets you back 100 euro. Leaving a 100 for hotend, rods, bearings, and all other parts...

The day has come that we are launching the drawings of the Ultimaker 2 and share them with the world. We are excited to see what kind of ideas, innovations, improvements and products this will lead to. We will continue to share our knowledge and experience and look forward to achieving many remarkable 3D printing goals together.
