3D Printing Community news and update 
MAY 2016

Another community and 3D printing news and views update -

Video update for May - Or watch here in HD over on YouTube.



Hi Everyone, another update from the 3D Printing community, I hope you like it. Please leave me a comment - Thanks.

Here is what I'm discussing, and to make it easier to navigate, check these timecodes and jump to a point that interests you -

Start - Thank you for your Feedback
2:08 - Makerbot Going to China
2:48 - LulzBot Taz 6 Launch - (Not Going to China)'
4:32 - Kickstarting OLO
5:19 - Kickstarter - Two more Delta Printers
7:17 - Kickstarter - Polymaker Polysher & Polysmooth

13:03 - Community  * Drama *
15:23 - Development & Innovation
17:15 - Materials - eSun Cleaning Filament
19:40 - Things I'm doing...

It's mostly all in the video above, but I have also included a few further notes below for anyone that wants to read. Also some images of what I have been doing with the E3D Titan extruder and a new design of a quick-fit carriage for the BigBox.

Firstly thank you for all your comments and feedback, it's really helpful for me. I have limited time to do 3D printing, and don't have adverts on my channel or blog for any sort of income. It's good to know what I post and share is worthwhile doing and still of interest to you.

Generally I had similar feedback and comments on Youtube, blogger and Google+

I have taken the general feedback to be - that you like my development projects, and want to see more - like in the early days of 3D Printing.

No one commented about facebook, so that's great - I'll continue to totally ignore that.



April turned out to be quite a turning point for some in the 3D printing community.

Pinshape

Image from the Pinshape blog.

We found out who saved Pinshape and that turned out to be Formlabs. Interesting as I really expected Shapeways or one of the other 3D Printing services to snap them up.

Time will tell what Formlabs brings to the model sharing community and what this means for designers using Pinshape. It looks like the original Pinshape founders are now out of the company, so maybe we will see some new direction being applied by Formlabs soon. Read more about the news on the Pinshape blog here.


Makerbot

Makerbot declared itself unable to manufacture in the US, and now plan to offshore manufacturing of desktop 3D printers to a Chinese company. They seem set on death by 1000 cuts. The wider 3D Printing community continues to ignore them. Makerbot blog post here. Enough said.


LulzBot

As an alternative and more positive view, Lulzbot announced the Taz 6 -


Lulzbot still manages to be the most open-source 3D printing company, anywhere.

Matterhackers have them on pre-order for $2.5K. More info should be available on the Taz 6 in a few weeks when the embargo is lifted.

I have not seen any recent comments from Printrbot, but I expect Brook is also still planning to do as much as possible with self-manufacturing and worldwide expansion. Looking forward to some updates from other global 3D Printing manufacturers in May.

I'm really interested in seeing how the US and European 3DP manufacturers navigate through the next 18 months. I have a feeling we are now in the productive phase of desktop 3DP, and even the temptation of ultra low-cost machines from China is starting to subside.

I just wish the RepRap Pro had managed to last out another 6 months, things seem to be turning as long as you are still innovating.

So many Kickstarters -

OLO

OLO got funded to the tune of $2.3M - over 3000 comments on Kickstarter and not a great deal of response from the creators. I actually think this could be the last big 'low cost 3D printer campaign' People are finally going to get smart that a 'very good, reliable and easy to operate' 3D printer is still some long way off, and you need to spend more than $99 to get something worthwhile even trying to use.

I wish them all the luck, but I'm also predicting this one is not going to go smoothly at all. We will check back before the September deadline to see...

Polygon Delta

Billy Zelsnack Polygon Delta 3D printer kit over on Kickstarter - $24K - all sold out - well done Billy, this has been one really interesting development to watch over the past 18 months.

Spatial One Delta

Andrew Wade - Spatial One - Delta Printer has just started over on Kickstarter. If you are looking for a rock solid Delta printer kit, than do investigate the Spatial One


Polymaker


Polymaker - Launched the Polysmooth and Polysher - over on Kickstarter. It's had a tremendous response and is currently at $320k - I have backed this project and look forward to seeing the end result.


Mr Beam 2 


Mr Beam 2 - just got funded, reaching almost 1M Euros over on Kickstarter. Well done!


FormBox

Formbox - $245K for a vacuum forming box - key selling point seems to be that by using your own vacume cleaner make this machine possible. Very disappointed this is planned to take yet another year to be shipped to any backers, you could literally design and make one in a single weekend. Maybe I'm missing something, but what's with the 12 month timescale?


OctoPrint


Gina managed to get a successful Patreon campaign up and running so she can try to support the open-source Octoprint a while longer. Gina is still looking for sponsorship, contract work and generally anything that can help keep her in work and food.


Tom's 3DP


Tom has also decided to go for 3D printing full time - well done and good luck with the adventure. Anything I can do to help, just let me know.
Community drama - This is the calm down and chill out section of the news.

E3D and the BigBox crew caused some fuss over on Reddit with a recent mascot competition. It looks like a poor choice of wording in the competition rules (about not having to give away the BigBox as a prize if they didn't have any suitable entries) made a few people leap to the idea that designers were being used to provide free services etc. Read as much as you wan over on Reddit.


Innovation and materials -

I visited E3D last week, they are in the middle of another big expansion. This time Unit 3 is being kitted out for a monster research and development lab. Packed full of tradesmen, fitting the rooms for science. Plenty of new developments, materials and projects.


And the EDGE filament will be coming soon...

I also checked to see if they really did have the worlds supply of Haribo :)

This was Nozzle world.


I didn't take the peanut scoop... Honest!



They handed me one of their new silicone boots, this wraps around the hot-end heater block and both helps stop material build-up on the nozzle and also insulates the heater so part cooling fans can be more aggressive while also keeping the




I tried out some dedicated hot-end cleaning materials - by Esun filament, You can buy it over on the E3D website or Printedsolid - Anyone else stocking it, let me know and I'll add a link.


Some of the stuff I'm doing -

Project snowflake is finished, look out for an update on that project, done with my daughter.


The steampunk octopus is also finished, another one done with my daughter. I requested an interview with her, but was 'far too busy' out playing to comment.


I seem to be in an ever state of testing out new materials at the moment. Really interesting but also quite time consuming.

Testing out some colour gradated filament - interesting, but inconsistent and not quite as exciting as first thought.

Lots more work on paste extrusion and bioprinting applications - more on that soon.

I'm also trying to clear out all the projects, posts and video's I have not had time to finish. I'll get them all done over the next month and then get onto even more new developments.

Titan is performing well - and so is the new E3D Edge filament.



 Decided to re-design everything on the X carriage, extruder mount and 360 Degree fan cooling duct.


I have made a new quick-fit extruder carriage for the BigBox. I wanted it to fit the Titan well and also allow easy switching of extruders.






I had to jiggle (technical term) the heated bed forwards and up by around 30mm to allow the now much lower Titan setup to reach the build platform.







And for ideas and inspiration, here is a short 60 second video on what to do with all those spare ends and samples of 3D Printing filament - It was my youngest daughter's idea. Great fun.



Yea, That was April!

May is already looking interesting, see you next time.

Rich.

Jammed Fr!gg!n Nozzle! - #30DoC Days 15...18

An update! - life and frustration with things failing on me temporarily got in the way of 3D printing :), but I did managed to design and print a few more things over the last few days while my main printer was down -

Firstly I had 4 jammed Nozzles in the last 4 days ! That's something that has not happened to me for about 9 months now, really annoying, but at least I worked out what was causing it! - I was not amused... see below for an insight and some questions...

This all started because I wanted to print a few things in Translucent plastic, and the only stuff I had was some old (about 1 year) Chinese PLA from Esun, I had given almost all of it away and stopped using it about 9 months ago when I switched over to use Faberdashery, Orbi-tech/GRRF and Ultimachine PLA's.

It seemed to print well and I made a few things, then I did a test print of a new extruder and it jammed up Solid, ground the hobbed bolt and stripped the filament.
The first two failures, little did I know what was causing it - see below - 

I tested a few things and came to the conclusion my hot end had failed in some way so, I disassembled it and investigated.
An hour later I had cleaned everything and checked all the hot-end parts, and it all looked fine so I re-assembled it.

I switched over to some Black Makerbot PLA and finished my test print, It all worked fine.

Then the new Reprap challenge appeared (Impossible Spheres puzzle - proposed by Richgain) and I thought   I would try the translucent (Esun) Chinese filament again - I printed with Yellow, switched to red and back to yellow and then my nozzle Jammed again.

'Bad' Esun PLA - see details below.

With the nozzle hot and some manual pressure on the drive gear I inserted a 0.45mm drill bit into the nozzle, it immediately allowed PLA to extrude out, I twizzled the drill bit and removed it, the nozzle jammed again straight away. I removed the extruder and disassembled it cleaned out the hot-end and continued on printing.

I had another jam and another clean out, then it jammed again so I switched over to some White PLA and attempted to push out the block, it did not work, and after using the drill bit again and having the same results, flow when the drill was inserted and no flow after removal I concluded that something was inside the nozzle and I was pushing it up with my drill bit, it was flowing back down and blocking when the drill bit was removed.

It was only when I cleaned out the nozzle again with the help of the white PLA I noticed a dark spec in the blocked filament.

I thought it was part of my hobbed bolt's teeth to start with, but after looking at it closly I was starting to think it was a ball bearing...


I checked it under a microscope and - I was right! 


This ball bearing was removed from my hot-end after using some PLA manufactured by Esun PLA.

Since this had happened 4 times and wasted quite a lot of my weekend with cleaning out my hot-end I checked over the last 100m of this filament and I found another 3 ball bearings embedded inside the filament!
The question is how and why are there ball bearings in this filament?

I had ignored bubbled in the filament before this as it's a common fault of low-grade / low-cost filament, I just had not expected to have contaminants also embedded inside. Signs of the bubbles along the filament usually indicated a ball bearing close by.

I had four blocks this time and I found 3 more bearings in the remaining filament, god knows how many more  there could have been in the Black stuff I had struggled with in the past?

So if you have any filament with bubbles you can see, check if it also has any contamination in it.

If you were looking to block a 3D printer hot-end in the most effective way, using a ball bearing bigger than the nozzle size is the best way I can think of, so is this an accident or intentional?


I stopped using the Black Esun PLA last summer after it caused so many blockages and fine stringing with my 0.4mm nozzle, I now wonder if they were also ball bearings or other contaminates, 
Image from Last summer (2011) - the black Esun PLA also shattered on me last summer, I still don't know why.

The moral of the story, you get what you pay for, buy materials from a source where you know who makes it, and watch out what you put in your 3D printer. 3D printing is already hard enough without nozzle blockages to deal with.


I will take my revenge on the last 100m of this Esun PLA, it's going to make a nice piece of PLA scrap Art, not that this nasty PLA deserves any more of my attention... I won't be putting any of this in my 3D printers ever again.

Has anyone else had any experiences like this? am I very unlucky?

Translucent plastic can look really amazing, just watch out where you get it from and what's in it!.

I am still after some high quality translucent PLA, if anyone can suggest a good source.

The only other thing that comes out of this experience, is that if we could find a way to control a bearing in a nozzle you could almost completely stop any ooze in a dual extruder set-up, we were recently discussing how to overcome dual extruder dribble over on the forums, if someone can think of a valve, I can now vouch that a ball bearing makes a perfect blockage and a 0.45mm drill bit acting as the 'pin' releases it.

And now my printer is back up and running I managed a nice print for the RepRap Competition with my Faberdashery PLA -
Slic3r 0.8.3 - 0.3mm layer height, 60mm/sec print speed, 0.5mm nozzle (or so I hope after all the blocking and clearing incidents!).





I feel better now, having vented all that.

I have some Raspberry Pi, a new extruder prototype and some other interesting things waiting to print out, I'll catch up on my missed #30DoC days now.

Thanks for reading.

Cheers,

Rich.
