Needless to say, I was a tad overwhelmed with the sheer number of exhibitors. Main stops were Edmodo, FormLabs, LittleBits, Stratasys, and MakerBot.
MakerBot people were nice and apologetic about their devices, as usual. They all seemed a bit preoccupied.
FormLabs people were great and super nice. They answered so many of my questions
Since we have one of each of FF Creator Pro and FormLabs 1+, and they behave like they should, they don’t have names other than “Creator Pro” and “1+”.
MakerBots on the other hand…
- IronBot – A Replicator 5th gen that requires constant stroking of the ego to reassure that the filament jam is not a filament jam, and to continue printing.
- RoboBot – A Replicator 5th gen that has been printing fine. I’m holding my breath because of the other MakerBot’s issues.
- Pinny – A Replicator Mini that was printing fine but had a slight rattling noise whenever she was moved. We think there may be a pin stuck or something.
- Homie – A Replicator Mini that constantly displays homing and thermocoupling errors. He’s louder than the rest and works fine on the rare occasion he works.
- ProdigalBot – A Replicator Mini that has worked from day one. ProdigalBot is the litmus test for extruders. If they fail on ProdigalBot, the extruder needs to go.
- (Returned) ScarFace – A Replicator Mini that printed fine, but when it came in, had a deep scratch on the front that someone tried to cover up with a Sharpie.
- (Returned) Picasso (Dali) – A Replicator Mini that could not print straight for the life of him. Picasso replaced ScarFace. I almost regret returning ScarFace if these printers were going to be this unreliable.
This was supposed to be a cube with the CSU logo on top.
- BatBot – A Replicator Mini that printed great out of the box. BatBot was a refurbished mini that customer service sent out because I would have to wait a month for the a new one. Being in the middle of STEM Honors camp, waiting was not an option especially because of the other jamming extruders. BatBot replaced Picasso.
We prepare secondary mathematics and science teachers. I also teach the middle grades methods course and work with K-12 in-service mathematics teachers. See this post for why we chose these printers instead of others.
1. I plan to infuse this technology in my Project Based Instruction course with secondary mathematics and science preservice teachers.
2. I would like for my preservice teachers to take these into the classroom and use with the K-12 students.
3. Preservice teachers will also have the option to make manipulatives for their class, whether it be a DNA helix or the London Bridge (for scale factor).
And so the case for:
- 4 MakerBot Replicator Minis
- 2 MakerBot Replicator (5th generation)
- The scanner helps digitize something that may not be available online or easily created.
- Depending on the design and function needed, instead of printing on the MakerBots, if we needed something stronger or more detailed, it would be printed on the Form 1+.
Thus we have:
- 4 MakerBot Replicator Minis
- 2 MakerBot Replicator (5th generation)
- 1 Digitizer (3D Scanner)
- 1 FormLabs Form 1+ Resin Printer
** Added bonus for having all these machines was that in a class setting, students 24 students were in groups of 4, each group at a table with a printer, and that was theirs to maintain for the session.
There are a lot of things to consider when thinking about buying 3D printers for the first time. The who, what, when, where, and why were important things to consider. Click here for the post about buying one for yourself.
- Who. I know you’re awesome and that you will devote an awesome amount of time towards making this work. Be realistic about time commitments with regards to the following answers.
- Who are you? How much money do you plan to spend? How much is in the budget for repairs?
- How tech savvy are you and others using the printers as well? What is your experience with 3D printing? How well can you Google answers to your questions? Do you have a supportive IT department?
- What. So many choices. What to buy? Below are some questions to consider before having your heart set on what someone else bought.
- What are you going to do with the 3D printer(s)? Look at the materials, level of detail you want, and how big are the things you want to build. Can they be pieced together if too big?
- Will this machine fit all your needs? If not, are you considering an ecosystem?
- When. When will you need them?
- With some brands of 3D printers, do not expect them to work out of the box.
- If you have never worked with 3D printers, expect at least 10 hours (not including print time) worth of work before you decide to take on printing orders from others. Expect additional time investment with MakerBots.
- Where. These machines take space. They also take workspace. Be realistic about the amount of use you want out of them.
- Where do you want to put it while you use it?
- Where will it be stored if not where it is used? If you store it somewhere not where it is used, it might not be used as often as you would like.
- Is there a general area where all others have access to it as well?
- Why. Yes, let’s all agree that these little additive manufacturing machines are cool. Other than that, why are you buying these?
1. I’m pretty tech savvy. I can maintain the FF Creator Pro on my own. Maintain 4-6 of them and be IT for them? No. My colleagues can call MakerBot and talk to their customer support whenever they need to. I did not want them to have to troubleshoot anything if it came to that, but if they needed to, there’s customer support. MakerBot has a purchasable 3 year all inclusive warranty and is easier to approach with a use friendly interface.
2. PLA will serve most of our needs. For the finer prints, the Form 1+ will print with resin.
3. I needed it sooner, and they may or may not want to use them later. I did most of the setup. The point for me is to get them on board and using the technology.
4. These take room. If they were just for me, piling them into my office was fine. There were some noise complaints, but the printers finally found a home on counters in a dedicated classroom with lab hours.
5. Other professors in the the team teach physics, mathematics, and sciences. They eventually want to use these for their purposes too. So far, there is no need to stray from PLA or resin.
My simplified spreadsheet:
|MakerBot – crowd funded backed by Stratasys
||Longest established company. 3-year warranty available for purchase. Minis can be portable.
||Bad reputation for putting things out before they’re ready. Extruder* problems. Only prints PLA.
||4 minis and 2 replicators to buy. 4 minis to take out to schools if need be. X2 and Z18 currently not worth the investment. 3D Scanner.
|Cubify – crowd funded backed by 3D Systems
||Second longest established company. Fewer complaints about extruders.
||Made a mini to compete with MakerBot, but had to pull it due to failure.
||None. The max warranty was 1 year and limited online support.
|FlashForge, PrintrBot, AirWolf..etc
||Cheaper than MakerBot, less problems (after initial setup), and better prints. Prints ABS.
||I would be your technician. ABS needs venting when printing.
||None. After looking into all these companies, decided that we needed another material.
||Form 1+ prints complicated things and uses resin so it is more sturdy.
||Resin left in resin tank needs to be used within 2 months. Need to measure amount of resin carefully.
||Form 1+ resin printer with extra accessories. There is a extended warranty that you can buy. The other resin company only had 1 year warranty.
*Extruder: print nozzle on a 3D printer for filaments (plastic in a roll like PLA and ABS)
