....a few sharp students will learn quickly the proper procedure for clearing clogs and repairing the machines

I'm still not convinced about this. I'm not convinced it'd even be a good idea to let kids clear clogs.
a procedure that at best involves stick in needle thin piece of wire into a hot hole in a bit of metal.
and at worst involves near complete disassembly of half the machine, holding soft metal parts with pliers and possibly burning out plastic with a torch.

there would be too many burnt kids by the end of the day.

it's not that I have a problem with kids having access to tools or anything, we had electronics in our school and used soldering irons, (one kids deliberately burned another kids face) we etched our own boards with ferric chloride etc we did metal work with lathes and milling machines, (the only tools we weren't allowed to use was the band saw and press brake)

so I'm not saying that kids shouldn't be allowed to do dangerous stuff, I'm just saying that this is far too fiddly to want to let kids learn in a short space of time.

I also can't imagine kids having the attention span to make this practical.
nor do I think the lessons would be long enough to actually let kids be able to print things in vast numbers.

Lets consider the numbers,
generally a lesson/period length is 1 hour.
for practical technology lessons it would not be extraordinary to have double periods (given that there is a certain about of get out and clear up time needed. also those students that aren't currently in metal work/wood work, (or now plastic work) may be in a home ec lesson where there is also a baking time.

inside of two hours would would likely get 3 students to print parts that took 20 minutes to print.
a twenty minute print would be one very small keyring. (lets assume a shopping trolley token with an initial letter on it.)

that's a lessons start at 0
Printer gets turned on at 10
printer is hot at 20 minutes into lesson and first print starts.
1st print finishes at 40 minutes
ten minutes to cool and come loose from the bed puts you at 50 minutes
at 60 minutes the printer is hot enough to do the next print.
at 80 minutes that print will have finished.
at 90 minutes the part can be removed, at 100 minutes the printer would be hot enough to print.
the last child may need to leave class ten minutes late to be able to collect their print.

so realistically a two hour lesson can produce 2 small prints, (possibly 3 if you're lucky)

in a class of 30 that needs 10 2 hour periods. or ten weeks. which realistically is the whole semester, just for printing in lesson time, and includes no design time, (you're going to need to learn how to design before you can print!)

and that assumes that there are no clogs, no failed prints, no skipped steps, no bad designs no times where the filament runs out halfway through a print. no times where it doesn't stick to the bed properly.



I stand by my earlier statement, fused filament 3d printing is a cheap way to build things for hobby or small cottage art-craft / prototypes.

but it's not ready to be placed in front of scored of kids all wanting to print their little trinket.

it's not fast enough and not reliable enough.

Re: High School Teacher Looking to Check Out Your 3D Printer for Research

Caswell Sadly in the US theys tarted fasing out alot of the tech and vocational ed classes in the lat 80's and early to mid 90's in favor of classes centerign on college. I think maybe less than 10% of schools actually have any classes thatinvolve anything very complicated. This is due to the high rate of lawsuites from parents. And the lack of common sense of students.

Re: High School Teacher Looking to Check Out Your 3D Printer for Research

I think that you could be working a little too rigidly danny.

Kids will either love the concept of this, or not care. If the class is compulsory then make it that not all students have to print something, Allow students come in out of class hours, either during lunch times or after school. Make a 3D printing club. It sounds like Shane is enthused and supportive of this idea, but not all students will be. You give students the chance, and take the ones who grab it.

Making printing a design optional for the class, give them times to come in and get it printed if they want, but it does not effect their grade. Take the students who are captivated and grow them into mentors and managers to run the printer out of hours.

When I was at secondary/high school. I spent almost all of my lunch times in the design and tech department. Either using computers to program or hack the network (out of boredom), or making things. Schools have become far too rigid, with standardised testing, let this be a little bit of hope to students like myself. Who were so mind numbingly bored with most of the "tech stuff", and took our frustration out on hacking the IT network. Don't write all the kids off as short attention span luddites, there are plenty of kids around who just need the chance. In one Tech lesson when we were given these awesome generic lego sets. I built a set of wipers connected to a 3 speed gearbox, with a reverse gear. I was so proud of it, but also frustrated that this was just through my own intuition and self taught knowledge. Nothing in the school curriculum attributed to it. I wanted to be taught more about these things, but felt there was no-one to help me.

Re: High School Teacher Looking to Check Out Your 3D Printer for Research

When I was in high school 20 some odd years ago, we had a machine shop and a electronics lab.  You could forego a study period to take "Independent Study Machining" or Electronics.  The class consisted of myself, one friend, and one instructor who would start us off in the beginning of the class, eat lunch, and come back at the end. 

They gave us a robotic arm, a conveyor belt, and a small hobby cnc mill through donations.  We made an assembly line that would mill our school logo out of plexiglass and sold them in the school store.  All of this was done through manuals, trial and error and very little guidance from our instructor.  Remember this is pre-internet so if you don't know you just have to figure it out.

Moral of the story is:  If they are interested, kids can accomplish a lot more than you think.  Add access to the internet and I wouldn't put anything past them.

I think it's a little soon for that, they need to catch up on orders first.  But I would think it's a good long term strategy.  Get people used to you so when they leave for other places they have a comfort level and hopefully a loyalty.

Re: High School Teacher Looking to Check Out Your 3D Printer for Research

I oversee the EdTech department at a K-12 school here in Ohio, and have been working on trying to get a 3d printer setup here. I truly believe in the 3d printer in every classroom idea.  But I am pretty pro-STEM to begin with!

I think alot of what students will be learning is actually the 3D Modeling and less about the mechanics of the printer.  Back in 2003 I took a 3D course at Ohio State Univ and the entire course was all about modeling.  It wasn't until the end of the quarter that our designs  took a physical form (and we had to outsource the printing back then!).  Even if we had a 3d printer in that college classroom, I don't think you would of seen the students clearing out clogs on the machines.  That is a maintenance task performed by a designated staff member.  Students could always join a 3D printing club to learn more about the workings and maintenance of the machines after completing the design course. The ability for students to burn themselves could be reduced to basically zero.

A 3D printer has many potential applications at a school.  For instance, it can be used to just print off objects to be used in traditional classes (like pulleys, dna connectors, animal skeletons).  All of these items can be printed at a fraction of the cost and on demand.  They can be customized learning objects to the class curriculum to help student engagement.

And back to my original point, having 3 solidoodles over 1 replicator will help cut down on overall printing times, give you backups in case 1 goes down. Not to mention the ability to have 1 to tinker and mod.  Plus you can have a real fast and loose .3 (or larger) profile to really bang items out.  I don't see a large need for students to be printing .1mm content.

For me the real question is the Solidoodle overkill for what would be needed. That is how I see the Replicator 2.  For most school projects I doubt you would even need a build area so large... you could probably get away with this on a Makibox LT, which means you could have 9 machines for the price of a Replicator 2.

I was a teacher for 13 years so I understand student mentality. Some will get it, some will not be interested in the technical stuff and some take the class because they think they can play around. I think the Solidoodle is appropriate for the classroom since it is an easy, open machine to work on. With a little guidance from these forums and Solidoodle, this machine would certainly add to the instructor's classroom teaching tools. If the school competes in Robotic competitions (FIRST Robotics, etc.), the printer could be a big asset for that group as well.

I completely agree with you that the Solidoodle would be VERY beneficial to a HS Tech program. Some students really like to play around and tinker while other are oblivious like you said.

Having 3+ printers is the ideal situation due to the amount of time it takes to print a model. The reason for this is because having 25+ students it will take over a month Per class to get a model printed... I do have to comment on the idea of having a quality Replicator 2. It would be great to have 1 quality printer in the class but I feel the students in an engineering or design class should also be using the printers in a hands on way.

Re: High School Teacher Looking to Check Out Your 3D Printer for Research

There will surely be at least a handful of kids that would LOVE to help build and then utilize a 3D printer farm.  That should be handled by an after-school club, rather then a class.  Let the kids with passion for this stuff dive deeper.

As I said about printing on glass, your heat-up and cool-down times are drastically minimized.  I pre-heat my glass, so when a print is done, I can start another within 2 minutes or so.  For small things, you can do 2-3 an hour.  if the items are small enough, you can also print a few different things at the same time, reducing the temperate delays even further.  Plus you can print Joe Student's part, swap the glass, and put Joe's part on the side, still attached to the glass, where he can separate it himself if he wishes. 

Just do it!  even if you have to start up a fundraiser to buy one...  Make a school logo or something (like cmetzel did) and sell that fine hunk o' plastic for $5.00    $10.00 if your students are brimming with school spirit.

you'll have a printer in no time.  and then shortly thereafter, your 3-d printing farm.

Re: High School Teacher Looking to Check Out Your 3D Printer for Research

Good call on the preheated glass. Ill keep it in mind. As for fundraising,  unfortunately all the money that is raised must be done through a club and the club that is associated with our tech ed department is TSA. I love this club bc students get to compete in in real world problems. They get to compete first locally at the school, then at states and then at nationals. As you can imagine this gets expensive so the current adviser allocates all the funds to go directly to paying for travel and other expenses.

How do you figure a Month to print the models for a class of 25?  I am assuming this printer would be in your classroom which you are in probably 6 hours a day.  With an average of about an hour per print you could probably run 5 a day which means it would take a week to get parts for everyone in class. 

If you are willing to run the machine when you are not at school then you can batch build probably 4 or 5 parts a once overnight and speed things up even more.  I don't think students have to necessarily "watch" their part being printed.

I was in TSA at my High School.  There would be tons of benefits in having a 3-D printer in that program. You might start calling some of these 3d printer companies and finding out if they have any special pricing for schools.

I have a class of 25 per period of the day and I have 5 classes a day. The room that I'm in gets utilized by 2 other classes (the students have 7 classes a day)  when I am on lunch and prep with only 45min periods.

I'm thinking in a global sense that uses the following equation for how long to expect a Tech/Design class to accomplish a project.  If it takes the teacher (who knows how to do something) x amount of time to do something then it will take the students (the ones learning and troubleshooting) 5x. I've only been teaching for little over a year but this estimate has really been accurate for my classes.

Although I love the idea... Unless I have had the printer for a few months and it is working flawlessly, then I would have avoid leaving it on overnight. (too much liability if something goes wrong.) 

I don't think students have to necessarily "watch" their part being printed.

If only I could believe that you walked away from your Solidoodle during your first print... lol

I agree that not everyone will enthused and grab on. But I'm there to expose them to all of the different engineering design processes that the world is using. The first project they would still be required to complete for a grade. Anything after that they would utilize it based on their need through their designs only. (they dont have to use it if their design doesnt require it)


Take the students who are captivated and grow them into mentors and managers to run the printer out of hours.


This is the goal. I have some students that are already in that role with some other equipment.

Re: High School Teacher Looking to Check Out Your 3D Printer for Research

Maybe I wasn't too clear,

I'm not that old (only 30) so the experience of education is not "that" far behind me.
Most schools do not have extensive STEM program's, mine did.

We had a wood working shop with lathes, there were metal lathes in the metal shop. Milling machines pillar drills a proper electronics lab where we photo etched boards.
We had a computer control room.
These were stocked with old acorns that we did computer control on, mostly it was programming traffic lights etc, the breakout board for the machines allowed us to actually "see and do" making computer controlled traffic systems.

We also had a cnc milling machine and a cnc lathe,

Nobody ever used them. I saw them used once, by a teacher.

I live about 8 miles from silverstone (race track) thy used to run a competition to build a radio controlled car. That's the only after school club that I ever saw in stem that was successfully attended by students.
The cnc mill was used to produce a arms for suspension from acrylic.

I really think the fused filament printers will end up bing a similar curiosity item in tech rooms, a little too complicated for students to learn a little too fiddley to maintain.

I've been following 3D punting for a long time (since I read about Adrian bowyers first Darwin machine in a staff news letter whilst I was working at UoB)

I did immediately see the potential for use in schools the same as everyone else has. But the honest truth is that the reality likely isn't going to live up to the dream.

The biggest problems are:
The software, you're going to teach kids how to use autocad in highschool? Good luck with that! (I assume that'll be extra classes I mean you still have to teach 2D design and drafting first?!

Then you have to go through all the design configurations re overhangs and support material.

Then the biggest killer is the time it'll actually take to print!

And machine maintenance,

As I said before 3D printing in schools? -yes.

Fused filament 3D printing? I can't see it, laser sintering is just so much easier to show more foolproof etc.

I've seen printers such as Dimension printers used quite well in the classroom! It really adds to the ability to work on projects and create different components for them to make some amazing things. (Dimension has a very good product that you rarely have any clogs.)

The biggest problems are:
The software, you're going to teach kids how to use autocad in highschool? Good luck with that! (I assume that'll be extra classes I mean you still have to teach 2D design and drafting first?!)

I teach my students how to use AutoCAD and they are quite adept at it by the end of February.

Weighing in late, but here it is from horses mouth:

The Solidoodle is already used in schools to great effect. Yes, we do offer an educational discount.
While we typically do not take part in the individual curriculum development, we have seen some
great programs put together with the Solidoodle.

Let us know if there are any questions on Solidoodle's and education.
