RepRap Report #2

End Stop

Somehow I can’t believe it’s been four months since my last RepRap update! I’ve got a lot to report…

In July I took the RepRaster 5000 to 3D Printing Camp in Madison, and that didn’t work out too well. The first problem was that I couldn’t get the bed up to temperature (and yeah, I print with ABS.) I didn’t notice the ceiling fan directly above me. I moved. I also managed to knock the Z end stop out of place, which made the extruder crash into the bed. No real damage from it, but I decided I needed a new end stop solution. The new one is way more solid. No easy way to bump it out of alignment.

I also took the RepRap to the Milwaukee 3D Printing Meetup. Once again something went goofy, but I did get it working fairly quickly after the first fail. (Just a few weeks ago I took the RepRap to BarCampMilwaukee7 and had no issues at all. Success!)

Power

At some point I got sick of all those damn wires coming from the ATX power supply, so in the process of making them shorter, I hosed something up good and ended up with a power supply that supplied no power. I finally got a smaller (and more powerful!) power supply. I’m not 100% happy about the mains not being totally covered up, so I should make a case for it at some point. It works very well though… much better than the ATX supply did.

Spools

My great spool experiment was a bit of a failure. I mean, at least I don’t use soup cans, and while I still think my idea was good (or at least looked good) trying to wind a coil of filament onto a spool is damn near impossible. Just ask my daughter, who had to hold back from laughing when the power drill kept slapping me in the head with filament. I’ll probably move to one of those adjustable filament holders you can easily get a coil onto. At home I end up just hanging the filament from the ceiling, so that works fine.

QU-BD Extruder

I ended up getting an extruder from the QU-BD Kickstarter campaign, and I haven’t bothered to assemble it yet. My original plan was to donate it to the DIY 3D printer we were going to build at Milwaukee Makerspace. Since we ended up getting a Replicator, we didn’t build a printer. It’s a 1.75mm extruder, and since I use 3mm now, I may end up switching to 1.75mm in the future, so it could come in handy.

Netbook

My best RepRap hack was getting my MacBook out of the picture and making good use of my old Eee PC 701. This was the first netbook ever released, way back in 2007. I’ve struggled with how to make it do something useful, and now it does. I’ve connected an old LCD display I got for free to it, and it sits on the shelf near my workbench. It does one thing… control the RepRap. It’s plenty powerful for that. I do all my modeling and slicing on my MacBook, so the Eee PC just runs Pronterface. And for traveling I can just bring the Eee PC and it doesn’t take up much room.

Mr. Pumpkintatohead

Hey look, it’s Mr. Pumpkintatohead! Nothing amazing, but I’m getting better at using OpenSCAD. I managed to design all the parts (minus the knobs) for my Laser Kaleidoscope in OpenSCAD (no, they are not parametric, but hopefully I’ll get better as time goes by.) I also managed to complete a home repair thanks to OpenSCAD and the RepRap. Hooray!

I’ve still got some challenges. Now that it’s getting colder out, and I’m printing bigger objects, I’ve got some warping issues. As winter comes, this may be my biggest problem. Besides that, things have been working really well. One thing I’ve found is that I’m not happy with my z height. It’s just 75mm, and I’d like to see a bit more. Oh, I also switched from Sprinter to Marlin, so I may be able to get a few more millimeters of height by just updating the firmware. (I was a little conservative at first.) I can probably gain a few more millimeters with a new piece of plywood under the bed. There’s always something to tweak with a RepRap…

I think the biggest change from June to October is that I am now confident enough that I can hit ‘print’ and leave the basement and I’ll come back to a successful print. I used to just stare at the bed as the skirt went down, and that first layer went down… in part because I was fascinated, but also in part because I always assumed something would go wrong. Things tend to go right almost every time now… it’s almost like having 3D printer at home is a normal everyday thing. :)

(You can see some photos of my prints over on Flickr. I’m way behind in taking photos of my prints, but there’s a few interesting ones in there.)

3D Printing Camp ReCap

3D Printing Camp Wisconsin

It all happened pretty fast… I think it was the beginning of May when Bob Waldron floated the idea of a BarCamp-like event focused on 3D printing past me, and of course I couldn’t ignore it. I helped set up the web site and did some promotion and sponsor-wrangling, because I figured if he was throwing such an event, I wanted to see it happen so I could go to it. :)

3D Printing Camp

Getting sponsors took a lot of time, but in the end (and I mean very end!) we got what we needed, and were able to cover most of what we wanted for the event. People got fed, Sector67 got a few bucks for use of their space all day, and nothing went wrong… well, almost nothing.

If you attended 3D Printing Camp you owe a big round of applause to Bob Waldron, but you couldn’t give him one on Saturday because he was not there! Despite all the comforts of our modern world, if your plane gets delayed, and you get stuck, you miss things… and Bob missed the event. (Don’t worry, this will just ensure he does it again next year.)

3DPrintingCampWisconsin

So what did we do? Well, we printed. A lot. And we also had a few sessions related to 3D printing, modeling, security, repairing things, and we just generally got to meet everyone else who is into 3D printing. Remember back when you were the only person you know (not counting online) who was really into something, and if you got to hang out with others who were into the same thing, how awesome that was? Well, yeah, that was it. I think we had about 20 printers, and saw over 60 people come through the door throughout the day. Not a bad turnout at all.

3DPrintingCamp

For me one of the highlight was learning more about Sketchup. Kemper Smith led an amazing sessions showing tips & tricks for 3D modeling and I took plenty of notes.

And then there was Tony Warren, who showed up with a partially done RepRap and got it printing by the end of the day. I can certainly attest to the fact that having an unfinished printer is something no on wants, so getting it running is pretty awesome.

3DPCWI

The event was pretty laid back, and plenty of people just spent most of the day (and evening!) printing, which is cool. There could have been more sessions, but when you’ve got all those printers in a room, you want to talk about them, and trade tips, and melt some plastic. It’s all good.

As for the RepRaster 5000, it started a little shaky because I could not get my bed up to temperature, then I noticed a ceiling fan above me! I moved and all was well, for a while. I printed a few things, and then I did a print that failed, then the next one failed, and then it was time to just give up. I had managed to knock things out of alignment earlier and I think things just went pear-shaped from there. Too much printing I guess. Once I got home I got everything back to normal, leveled the bed, and it’s back to normal. (It’s always a RepRap adventure somewhere…)

RepRap Report

RepRap

Here’s a RepRap update, which I plan to do every now and then to track the progress of the RepRaster 5000. (Yeah, that’s the name of it. At least until I come up with a better one.)

The RepRaster 5000 has been fully operational for about a month now, and I have managed to make a few things in that time. Most of my prints have come out okay… not great, but okay.

Pronterface

I’m using Slic3r and a pre-compiled version of Pronterface on Mac OS X 10.6.8. I’ve had one or two STL files that had some issues with Slic3r, but besides that it’s been a fairly solid setup. I’m still using Sketchup for some 3D modeling, and OpenSCAD continues to confuse me.

Slic3r

My first prints were on a sheet of glass taped down to my heated PCB. They turned out pretty bad. Because of the way the PCB was attached to the platform I couldn’t clip the glass tightly into place. Oh, the PCB was also mounted flat(ish) to the wooden platform. I ended up raising up the PCB above the wooden platform, thinking it would help it heat up faster (it seems to) and I’d also then be able to clip the glass to the PCB. This is way better. Easier to work with, for sure.

So now I’ve got the PCB above the wood (spaced with a few nuts and washers) and the glass attached to the PCB with bulldog (AKA “binder”) clips. My first prints on plain glass were hit and miss, and the ratio was not improving. I tried ABS slurry (which is acetone with some filament dissolved in it) but that was messy and still didn’t seem to work that well. I ended up putting Kapton tape on the glass, and then just using nail polish remover to clean the Kapton well before printing. (I’d prefer to use the nail polish remover over the acetone if possible, since it’s less smelly.) Finally, I was getting really good adhesion! (I’m doing two skirt loops 6mm from the print.)

Leveling Nut

The one thing that really helped printing (so far) was leveling the bed, which was completely impossible at first. With just the nuts, there was no way in heck I was going to get things level. Then I found the Parametric Thumbwheel, printed four of them, and at last… a level bed! Again, one of the great things about a RepRap is that it can (often) print its own upgrades. I’ve got my eye on a few other items that might make things better/easier/faster.

I’m at a point now where I feel like I can print things, and while they aren’t the best quality yet, that will change in the future, with more and more tweaking. I’m looking forward to sharing tips & tricks at the Milwaukee 3D Printing Meetup happening July 1st, 2012, and 3D Printing Camp on July 21st, 2012. If you’re at all interested in this stuff, either event (or both!) would be a great introduction.

MKE3DP – 3D Printer Fans Unite!

MKE3DP

As you may know, I finished my RepRap recently. But here’s the thing, you never really finish a RepRap. It’s a beast in need of endless tweaking. So yeah, it’s a never-ending project (if you want it to be) and I’m okay with that. I mean, once you get to the point that it works, you can start using it to upgrade itself. How many tools can do that!?

Of course you can actually make useful things, functional things, or just pretty things. There’s a lot a 3D Printer can do. I’ve only been at it for less than a year and I’ve still got a lot to learn.

So anyway, yeah, I’m really enjoying this 3D Printing stuff… so I figured, why not share it with others? So join us for the first Milwaukee 3D Printing Meetup! We’ll be meeting on Sunday, July 1st, 2012 at 1:00pm. We won’t be at our space because we’ve partnered with our friends at UWM for this one! Show up at UWM’s Kenilworth Square East Building, 3rd Floor; Room 368 on 1925 E. Kenilworth Place.

If you’ve got a 3D Printer, bring it, or just show up and learn about them. If things go well and there’s interest, maybe we’ll turn it into a regularly scheduled meeting.

(More info? It’s also on the Milwaukee Makerspace site and you can RSVP on Facebook if you want to see who else will be there.)

MakerBot Marketing

MakerBot Industries

I meant to write this post about a month ago, but writing it now just validates the points I was going to make anyway, so read on!

Back when I wrote 3D Printing is the Future, I mentioned a number of companies, including MakerGear, Ultimaker, and of course MakerBot Industries. Four months later, I’m going to update my thoughts on them, and specifically focus on what the MakerBot folks do in the area of marketing.

Wait… Marketing? If you read the piece in Fast Company you’d know that MakerBot Industries doesn’t do marketing:

… When I speak with MakerBot’s Keith Ozar, he seems offended when I refer to such undertakings as “marketing.” His background is in underground music promotion, and he joined MakerBot when the company advertised a “marketing experimenter” position in early 2011. MakerBot doesn’t really market at all, he counters; it actively participates in the community the company seeks to both cultivate and create, involving “people who are creative, people with imaginations.” That means a presence at Maker Faire-style events, where hardware hackers congregate, and more recently at comics conventions and the like.

Here’s where I haul out the disclaimer: I work at a marketing company. I also market myself, and the things I do. Almost everyone does, even if they don’t call it marketing. If MakerBot doesn’t want to call it “marketing” I’m fine with that, but let’s be honest, that’s what it is.

With that out of the way, let’s look at the marketing that MakerBot does…

MakerBot Web Site

MakerBot has a web site. Hmmm, that’s nothing special. Let me rephrase that: MakerBot has a good web site. Their web site clean, well designed, and organized. There’s a store, there’s info on the community, including links to User Groups, Twitter, Flickr, Google Groups, etc. as well as a link to Thingiverse. Their support page has a lot of links to their wiki, and then there’s the blog.

The MakerBot blog isn’t just some “look at me!” thing where they talk about themselves (though it has been a lot of that lately, due to the recently launched MakerBot Replicator.) The blog also highlights things that members of the community are doing/making. And the blog is updated very often. Very often. That’s key.

Ultimaker

When the Ultimaker came out I heard a lot of talk about how much better it was than the Thing-O-Matic, and it may be better, but take a look at the Ultimaker web site. It just looks like a blog, and as of my writing this, it’s been over a month since it’s been updated. And before that it was a month and a half. I know blogging takes time, but for a small company it can get you the most bang for your buck when trying to tell people about your product.

MakerGear

In the world of RepRap, reprap.org is packed full of information, but if you want to buy a RepRap kit, MakerGear is a pretty well known and respected seller of the Prusa Mendel kit. They also recently came out with the MakerGear Mosaic, which is their own design, and is a capable machine from all I’ve read.

Visit the MakerGear web site and let me know what gets your attention… if anything does. There is a “What’s New?” link on the home page, that links to a page with a post that was written nearly two months ago. (With a typo in the title.) I’m a MakerGear customer, and I think they’re a good company, but I wish things looked a bit more professional. For a first timer visiting their web site (or the Ultimaker site) I don’t think they’re going to be impressed.

But then, maybe these companies don’t want to impress people. Maybe they’re only targeting the alpha nerds, who know the inside scoop, and think that MakerBot is for people who don’t know better, and the real desire is for servicing a niche market. If that’s the case, then that’s fine… I honestly don’t know.

So besides the web site, what is the “MakerBot Marketing” you ask? I’ll just throw a few things out there.

MakerBot: has good photography, has good videos (including MakerBot TV), they have a curriculum for schools, are behind Thingiverse, they’ve implemented an Artist in Residence program, did the Project Shellter thing, scanned people’s heads, and on and on.

Some of those things take a bit of money, which smaller companies may not have, but there’s no shortage of clever ideas, some of which are relatively cheap, and if it gets people talking about you, isn’t that what you want?

So yeah, MakerBot Industries does marketing, and it may be marketing on their own terms, and in their own way, but in the end, if people find out about you, and keep hearing about you, that’s building your brand, and that’s worth a hell of a lot.

Here’s the thing: You can have the greatest product in the world, but if no one knows about it, you won’t have any customers, and no customers equals no business, so marketing is important… even for nerdy 3D printer companies.

(Oh, there’s one more thing that’s key to MakerBot’s marketing effort, which I’ll probably talk about in another post.)
