Alex,

I hope you don’t take the following as personal, it would apply to any similar service offer.

 

First, I would reject the provision of this type and scale of service by a member of rLab. Once we start paying some members for services that are so like those which other members give for free, then I think we will cause damage to our sharing community.

 

Second, this is a new service for you as a supplier. We need a supplier who has a proven delivery capability. Also, I fear you will be too flexible as a supplier of hardware and services, which would mean constant improvements to the equipment and service, which may be hard to distinguish from hacking.

 

Both of the above are individually show stoppers for me.

 

I am still eager to find a way to get a 3D print facility at rLab. Maybe we should approach Create3D or similar.

 

Additionally, I think that to ensure we get full use of a 3D print facility at rLab, we must give high priority to the trainings, on both the printer and on 3D CAD.

 

Just wanted to declare my own position that I am likely to dismiss the proposal content out of hand, before you make a big effort.

Richard

I think there is a feeling that we need more support than a 1 man business can provide.

Personally I like an Ultimaker or something more industrial. But I don't know any specific brands or models.

I would avoid Makerbot on principal since they have taken advantage of community input in the past, which is not really inline with the spirit of the hackspace.

I could take 3D printer, and can make an impartial recommendation for a straight purchase - but I have also proposed a managed solution from my business, so I am conflicted.  I suggest I could work with someone else on that.

Please would members take "Ownership" - i.e. become their own "Procurement Officer" - for each item proposed for purchase.

See the Ownership Thread

Items needing "owners" ( not a definitive list, just stuff that has been suggested)

Fire safety evaluation and extinguishers

Hardware hacking proposals

Comprehensive hand tools for both up and down stairs

The Great Lake

Door and windows upgrade ( double glazed?)

The sign

Floor finish downstairs

Rewiring ( I've taken that on )

The helipad.

3D printer

Water jet cutter

Large format CNC router. plasma cutter bed.

Loans or grants to other spaces.

 

Ownership doesn't mean that you make decisions for the membership - but that you act as a focus for member inputs.

The discussion you moderate needs pulling together into a document to "sell" the proposal to members and directors.

It must include costing details, supplier, arrangements for maintenance, who is going to be responsible for the item if purchased.

I feel there is a degree of urgency and a real danger of making poorly researched purchases if nobody steps up to take on the basic research.

We have a bunch of ultimakers at ICAH and the quality of output is very impressive. I've actually enjoyed using a 3D printer there (!!!)

However, they do fail, and the prints do take time. It's a decision for the Hackspace to make about leaving printers running unattended. 

So do roboxes, makerbots, UPs, and the rest i can only assume.

The most maintainable, from my understanding, are prusas. 

Also, dual extruder for soluble support. Our dual extruder robox has been back and forth for repairs so much i haven't been able to give it a proper try. Seems awesome tho.

Ultimaker 2+ its essentially plug-in and play. Doesn't need to be connected to a PC, can cope with a wide range of decorative and function filaments (inc. the new skin tones Colorfabb nGenFlex for prosthetics). There will still be maintenance, but that's mainly limited to hot end blockages (rare), and some semi-annual oiling etc.

Personally I use Simplify3D (Paid) as my primary slicer, but Cura is great as well, and has user levels from simple (just choose quality) to advanced (3D infills, fuzzy prints etc).

My only point about getting a solid 3D printer is that having the device won't suddenly make everyone 3D experts. To make the most of it we would need to commit to some 3D design lessons / workshops / courses. Happy to share my experience in that arena, but there a numerous toolchains depending on the kind of 3D object you want to design.

WRT toolchain.
I run two types of printers, one Prusa style (Mendel90) and a delta (Fisher).

My toolchain is;

Design - InkScape, OpenSCAD, SketchUp, TinkerCad, Fusion 360 and custom
Pre-slicing - MeshLab, Meshmixer and Netfabb Studio
Slicing - Simplify3D (commercial), Slic3r and sometimes Cura
Printer control - Octopi for Mendel90, Duet web i/f for Fisher

Hi all,

I popped along to Creat3D and had a chat. They can't do anything it terms of discount so the cost would be as on their site;
- Ultimaker 2+ - £2,154.00
- Ultimaker 2 Extended + - £2,814.00

This comes with technical support for the duration of our ownership of the printer. However the manufactures warranty is not as good as some others, https://ultimaker.com/en/resources/16575-ultimaker-warranty

They also suggested some other printers in a similar price range that may be better suited for use in rLab, ie simpler to use (less settings to mess around) and more fault tolerant;

- Up Box Plus - £1,920.00
   Enclosed build chamber, helps with reliability
   Out of filament detection
 - MakerBot Replicator+ - £2,638.80
   Smart extruder, can monitor filament flow and detect faults

The sacrifice for these two however is flexibility, you can not use the amount of materials on these as you can with the Ultimaker. Do any other members have experience with the MakerBot Replicator+ or Up Box Plus? 

Creat3D also offer an installation and training service for £598.80 - http://www.desktop3dprinter.com/training/3d-printer-onsite-installation-training.html

For what it is worth from am veering toward the Up Box Plus as it sounds like it could be a good fit for something that will just work and people can't do too much to mess it up.

We're testing an Up Mini 2 and a Makerbot Replicator Mini+ at ICAH at the moment. They both work, if I were to buy one it'd be the Up 2 Mini.

Our existing printers are Ultimakers and Roboxes and they're good. The ultimakers I rate better as they're easier to maintain, but the roboxes go back to base and get fixed when they break. 

If it weren't Reading Hackspace, I'd recommend one of the new prusas with dual extruders, but I just know it'd get mullered. Same with a Lulzbot or a printrbot.

I think something fully (or mostly) enclosed that 'looks the part' like the up 2 mini or an ultimaker 2 go would be great, even if it sacrificed some size, features or quality, as if it looks more like a finished product people might be less likely to fuck it up. 

Not my call.

I don't see anything special about the reels we have, and there's no electrical connection between the reel holder and the printer itself, so unless they're special diameter, we can use whatever I guess?

I don't have the printer in front of me now but I could measure it on Wednesday?

Nice offer but I think rLab (currently) fails both pre-requisites :(

The Zortrax M200 is in another league of both print quality and reliability even than the Ultimaker 3, and is considerably cheaper than the Ultimakers and Makerbots.  It also has some big advantages over the Ultimaker in terms of accessing the extruder internals to clean and maintain.

 

I have demo’d one extensively at the iMakr store in Farringdon, and it is the only new single nozzle FDM printer I would buy for my business.

               

I’d strongly back any move to buy one of these for rLab.  The only better featured printer we could get would be the Ultimaker 3, for dual extrusion, which I’d personally love to get to use, but I think the Zortraz would be more robust for the rLab environment and far better value.

 

I sadly agree with Ryan – Lulzbot Taz 6 would be a great choice – great quality, robust, super open source in both ethos and practice – but it’s not much less ‘hackable’ looking than our current printer.  If anyone’s looking for a printer for themselves, take a look at it!

 

Experience with MakerBot… yes, I have that J  I only know from discussions with Creat3D that in the newest machines the Smart Extruder has been much more reliable than I saw when working for their UK distributor in Service & Support.  The concept was always good, and so if reliability has moved on significantly, they have the big advantage that spare smart extruders can be kept and swapped out instantly in the event of a jam.  Makerbot’s software ecosysytem is the standout benefit however – their network printing, monitoring, front screen interfaces are better than any others, and when it comes to preparing an STL for print, their MakerBot Desktop (Now MakerBot Print) software is by far the easiest to use (and is why I use Replicator 2’s for my 3D Hubs business).  But the cost of it plus a spare smart extruder or 2 is a lot higher than the Zortrax.

 

 

So, for me, selfishly, I would say I’d love an Ultimaker 3 for its features, but for rLab, I would recommend the Zortrax M200 for best quality, inherent reliability and value for money, or MakerBot Replicator+ for ultimate ease of use especially for newbies.

Really?  I’d say we pass and should go for it! 

 

-          While we have the Thames Valley RepRap (and it works, as I’m always reminding people) it’s clearly below most people’s expectations of ‘reasonably functional’ these days, and its value is as a demonstrator.

 

-          We do meet all the specific criteria of the Hackspace foundation, as of our recent vote for new directors!

 

Am I missing something?

I (and I know of others that) would be against a printer selected for it's 'hackable credentials' or a printer brought with the intention to be hacked at some point.

Would fully support and be excited by the suggestions of buying something that is ace out the box with a great maker/support community behind it (like the ultimaker).
I'd also worried about coming in to find the printer in a different configuration to what I'm used to or previously created stuff with.

I fully agree, this is a tool to be used to hack and NOT hacked on itself. 

If people wish to hack on a 3D printer the Rep Rat will still be around (probably). Maybe this can be upgraded to a Persa or Lulzbot, but that should be a separate discussion?

How does the whole 3 month only warranty fly with UK law?

It's a 12 month warranty, they just say they reserve the right to charge for labour/shipping after 3 months.  I don't think that is legal, anything under 6 months is supposed to be fixed with costs covered.  But you could contest that at the timeif necessary because you can't give away your statutory rights.

Totally agree Oliver.  Any new 3D printer we buy is a TOOL not a PROJECT.  DO NOT HACK!

 

And yes, we should keep our existing Thames Valley RepRap, as a demonstrator.  Even it doesn’t want to be randomly ripped into the moment we have something shinier, a lot of effort went into making it robust while still appearing 100% open RepRap.

 

If anyone does want to hack 3D printers at rLab, shout!  I’d love to help support that, have a chat - it’s what I do J

 

Cheers

Alex

3 month warranty doesn't fly AT ALL on the face of it - but may stand up to closer scrutiny.

For at least the next 2 years we're covered by UK and EU law on this.

The product has to perform as advertised, for a period of time which is reasonable given the factors of the sale.

Most shops and manufacturers try to lower our expectations by touting a 1-year warranty - but in practice, courts have repeatedly set the minimum bar around 2 years for most consumer electronics. Product failed after 13 months? Challenge it!!!

The length of time something should last is variable according to the type of product, and the cost of the item. An Ultimaker plywood kit a few years ago could reasonably claim to be a budget, experimental device. A current Ultimaker is a premium machine, relatively well established in production. It should have a longer lifetime expectation.

Where Ultimaker are probably more OK and just setting expectations for consumers, is that their machine is inherently very repairable. It's at their choice how they keep it running, and if they are able to send you new parts, you have no right to expect to return the machine because one part of it has broken. 3 months may be simply stating clearly an early lifetime period where if it goes wrong so soon, they rightly replace the whole unit.

The issue then becomes one of selling - are people buying an Ultimaker expecting a machine they will be fixing if it goes wrong, with good support in doing so, or a 'just works' unit that will require minimal maintenance (there's no such thing as a maintenance free 3D printer). Discussing core expectations at the point of sale is the way to go, ideally summarised in writing.

What is our support situation with the Pirhana laser cutter? And are we planning on changing as part of the process that we are going through?

In my view the Ultimaker is a good choice of machine and the one that I would vote for. The support is unlikely to be worse that we currently have with the Pirhana - which is recognised as a tool not a project (So I suspect that there are other things that define a tool as well as the level of support..

I would not argue against the other options if that is what people wish to buy. I am unlikely to be use a 3d printer at the space unless we wander into Zortrax territory (printing materials that I currently can't and offering a much larger print volume than I have.

However, can I repeat the request that I made in the other thread - that the current 3d printer, which was donated by TVRRUG and has had a lot of work done to it by Alex and others since then, is returned to TVRRUG - either in the form of Alex or myself? There are other organisations and projects that could benefit from machine.

I think Malcolm makes a good comparison with the Pirhana Laser Cutter. To date, the support and repair of this has been down to Ryan, and the success likely down to fast reaction to faults, personal restraint and his authority.

 

We don’t not have a support contract, and we have not sourced spares (mirrors, lenses, air fittings) from the manufacturer.

We did make a modification to the Pirhana when we first installed it to force the laser off immediately if the cover is opened. Other than a few cabling fixes, and the addition of a port to allow access control (not actually implemented), it is not modified.

There are two things which don’t work, the aiming laser and the bed height sensor.

 

So, we need to ensure we both maintain/recover the “tool” status of the Pirhana, and have the same for a 3D printer.

Oh forgot to say the Up Box and MakerBot have a better manufactures warranty than the Ultimaker. The Up Box and MakerBot have a full 12 month warranty, but the Ultimaker will only supply replacement parts after the first 3 months.

Hi all,

 

I popped along to Creat3D and had a chat. They can't do anything it terms of discount so the cost would be as on their site;

- Ultimaker 2+ - £2,154.00

- Ultimaker 2 Extended + - £2,814.00

 

This comes with technical support for the duration of our ownership of the printer. However the manufactures warranty is not as good as some others, https://ultimaker.com/en/resources/16575-ultimaker-warranty

 

They also suggested some other printers in a similar price range that may be better suited for use in rLab, ie simpler to use (less settings to mess around) and more fault tolerant;

 

- Up Box Plus - £1,92000

Here is a summary of the 3D printers from Creat3D:

MakerBot Replicator+

Great for print reliability due to the detachable Smart Extruder+ which features filament error detection to identify problems with filament flow during printing. This is a consumable item which has a 6 month warranty, independent from the 12 month warranty on the printer.

Can print using PLA and also Tough PLA (requires Tough PLA Smart Extruder+).  

http://www.desktop3dprinter.com/3d-printers/makerbot-replicator-plus.html

 

UP Box Plus

A real ABS specialist, but can also print in ABS. Reliable ABS printing within an enclosed build space with perforated heated bed. Auto-levelling and nozzle height detection for easy calibration.

http://www.desktop3dprinter.com/3d-printers/up-box-plus.html

 

Ultimaker 2+ / Ultimaker 2 Extended+

Great for material variety but does not have the same features to promote print reliability as the other two printers. Easier for users to get themselves ‘into bother’ with customisable various settings. Does not print ABS well, but you can use colorFabb nGen for very similar material properties.

http://www.desktop3dprinter.com/3d-printers/ultimaker-2-plus.html

Hi,

I have a Doodle Poll (https://doodle.com/poll/3mgbmbwwdvx435v6) for a date/time to do a group demo of the 3D printers @ Creat3D's showroom. As time is short please try and respond by Sunday evening.

I can take up to 4 people to/from the rLab if needed.
