After a gimp update I tried out colour addition on a photo posted by Stevebhx. In the 1950s I bought an oil-stone from the hardware shop in the photo - used it to sharpen my ice skates. Owners of small hardware shops all seemed to be slightly grumpy - perhaps it was because they moved all that stock in and out of their shops every day.
29 and 29a buses used that stop and I travelled on those buses for school ...

They are also grumpy because someone they have never seen comes in asking for one Hodgkins H74 and complains because they wont split a pack !!.

Great job there but can you imagine the local H&S inspector visiting there today...unsecured ladders, goods obstructing the public pavement etc....he'd have a breakdown.

I have just bought myself a 3D printer. The machine itself is interesting in that it is ‘open source’ so you can do modifications, repair, and upgrades on the machine. It’s a step back from the built-in obsolescence you get in some high-tech devices.


A couple of things I have printed so far.

Mort, what brad/model did you buy? I am thinking about buying one, still in the early stages but what you have seems quite good!

 

[Morturn]

I have bought the Ender pro 3 V2 filament printer. This is a super printer that you can customise for your own needs. They are for on Amazon, but I bought mine directly form the manufacturer and got it almost £80 cheaper at £190.

The resin printer is an Elegoo Mars Pro, again a great printer that you can buy spare parts for. I broke a part last week, but Elegoo are sending me a replacement for free.

You're right about Chinese products; the only thing that,s come out of China and lasted for more than 12 months is Covid 19!! John.

I played the timbals tambour and tambourine and maracas at school. Some children just didn't have rythm. I can't tell you what my Nan called maracas. I shall put it on My Nan's sayings.

Your a bad man Morturn your going to cost me best part of £300!!! I've got some spare worktop space in the radio shack crying out for a 3D printer I'm a bit of a silver haired geek, love technology so I'm buying one.

Excellent, money spend on leisure or hobbies is money well spent. If your into radio or electronic things you’re going to love a 3D printer. You can make all the project boxes and enclosures. I am working on a ‘Useless Box’ at the moment.

Mort,

Intriguing and had I been a few years younger I would certainly have bought one. Not that much more expensive tham my A3 printer. What is the cost of the resin please?

Maurice

 

[Vivienne14]

Maybe in time it will reproduce lost buildings and artefacts on a large scale - and cheaply. A long way off, but this is mind boggling technology when you think about the long-term possibilities and uses. Great hobby Mort. Viv.

The resin costs between £25 to £40 a litre, depending on the type. You can do quite a lot of printing with the one bottle. The software will calculate the cost of the print based on how much resin it will use.

How do you go about programming a 3-D printer? What is it like for producing large thin-walled curved items? There is a very hard to find Bentley part, a cover for the lower half of the flywheel which is a simple shape like half a bucket, sliced vertically. Would this technique reproduce such a thing, even if it needed to be done on a professional machine it might be usefully cheaper than trying to make press tooling.

By coincidence I have also started to do a course in 3D photography in relation to historic buildings. What I have in mice is producing 3D models of at-risk buildings or those due for demolition.

I am also looking at how we can preserved grave markers in the same way, as the detail it quite remarkable.

Have a look at this 3D walkthrough of a project I am involved with.

 

[Vivienne14]

Wow, that’s a truly worthwhile thing to do Mort ! Adds a new dimension (sorry for pun) to historical records. I suppose provided the plans are prepared/available/catalogued before demolition any building could be 3D printed. What a great resource. Viv.

You are spot on there. The part can be drawn in a CAD programme like Fusion 360 to make the 3D model. The 3D model is then bought into a slicer programme, I use either CURA, LycheeSlicer or Chituboc to slice the file and prepare it for printing.

I have seen vintage car parts scanned with a 3D scanner too and the model built from the scans.

There are actually 3D metal printers too that can print parts or you can use the resin model as the pattern. Victoria Forge in Willenhall do this for their dies.

Absolutely Viv, just think about all of the wonderful graveyard monuments that have already been lost. We can now at least keep more than a paper record.

I am taking to Nottingham Trent Uni on this one.

Mort,

That's very interesting and unless you need huge rigidity, then it's obviously wise to include as much empty space as you can in order to minimise resin usage. One more question, are you using freeware or paid for software? I like the Sandhills project.

Maurice

 

[Morturn]

You can hollow the model then add internal support and drain holes automatically in the software.

The software has both free and paid versions.

Mort, am i right in thinking these 3d printers come in bits & do you need a degree in engineering to assemble?

My resin printer came out of the box working. Just had to push a small gasket on the cover. It was dead easy to get started, the instructions were clear and easy too understand. The only job to do is level the build plate. Again, dead easy and the manufacture has a video on You Tube.

The filament printer did have some assembly which was moderately complex, but I did it in around four houses. However, I do have that type of mind, so it may not work for everyone. I do know there are a few very good work out of the box filament printers, but I was quite keen on this one. Again, levelling the build plate is a bit fiddley but doable.

Nico,

Never try to learn on a souvenir instrument - it will prove to be most frustrating (and probably made in China).

Maurice

I bought a baglama saz in Turkey from a guy who made them who walked around carrying a number of them on his shoulder. I was staying in a small hotel and had got interested in the one the barman udes to play. He persuaded the guy that I wouldn't just hang it on the wall when I got back, so negotiated a good price for me. I still play it occasionally. Worth the struggle to bring it home on the plane

My lockdown music hobby has been to sight read sheet music and play it on my keyboard. I bought a midi keyboard which plugs into my laptop and a foot switch to control turning the page. At first I tried using pdfs but experimented with PowerPoint (finally found a decent use for it). The foot switch controlls the page turning in ppt easily and I can programme the order the pages are shown to allow for repeat verses. To move my playing on (just used to vamp chords and play the melody before) I bought some interactive emedia software. My headphones mean I can practice without annoying people.

Mort & John, a couple of years ago I spent some time at Oak Ridge TN (where a lot of work was done on the atomic bomb). It was a three day program and one day was spent in their 3D lab. They were printing car part and entire 2 seater cars. The primary sponsors or funders were BMW, GM and Toyota, a couple of others that I don’t recall. It is truly any exciting technology with new resins becoming available frequently.

My new hobby is woodwork; what do you think?

I agree, it is indeed exciting technology, I was watching a film of some metal 3D printing today.

My 3D printer has been running almost none stop this week. Best £200 quid I have spent for a while.

OK you have no doubt been waiting for some 'thicko to ask the stupid question, so wait no more here it is, obviously you don't have to load it with paper, so what is the finished object made of? How does it get in the printer and how do you get hold of it. Not in your hands, but who sells whatever it is, or is it IT magic that produces ready made origami?

Bob, great question and Mort has the answers for you.

I am using PLA (Polylactic Acid) Filamet. It’s made from corn, so is biodegradable. You buy it in 1Kg rolls, and it’s all coiled up like string, 1.75mm diameter.

There is a stepper motor with cogs that pushes the filament into the hot extruder that has a nozzle of .4mm diameter. Effectively, it melts and is squeezed out like toothpaste.

You can either 3D model the objects if you wish to make in a programme like Auto Cad. I am using a programme called Fusion 360. Alternatively, there are now millions of 3D models that people have produced already. Just google 3D models. I quite like some of the anatomical models.
