3d Printers South Africa

Any ideas of what glue to use to stick two pieces of PETG together. I read that superglue would work as well as Acetone? I tried Acetone and it did nothing except discolour the pieces. Haven't tried superglue as i need to get some but would like some input from the 3D printer guys who perhaps have the experience.

Superglue will work fine. I've used it many times on petg and pla. I like the gel type best when used on prints.
Acetone will only work on abs.

Anyway to improve this sort of thing at the back?

Came out OK otherwise.

That's where the layer ends/starts. That looks like your retraction isn't working so great it could be too little or too much or incorrect temp etc. The easiest is to just randomise the seam in the slicer.

Acetone is mostly for ABS. I just use a good epoxy as the sticks really well on most things. But I've used hobby CA glue(super glue) and even clear contact glue(it softens some of the filaments so works well if you rub the pieces together).

That's not too bad actually.
What you can do is look closely at the nozzle when it ends and starts a new layer.
Try to see when the defect occurs.

If it happens at the end of a layer (just before the z increase) or when the nozzle moves to new position on same layer (a travel move), you can try to adjust coasting setting.
If it happens at the start of new layer or after travel move, you can adjust the retraction.

Another setting that might help is the wipe option.

Given up on the Mambawire Satin PLA - it just breaks apart - tried numerous settings - my last attempt at slowing the fan, and running slightly hotter, it pulled apart coming off the bed (a benchy). Back to the colour changing one.

Hopefully find some normal coloured PLA next week

on one of the whatsapp groups, or facebook not too sure where, i do recall reading they had an issue with a certain batch of mamba satin , and AMS were offering exchanges, i am looking for the post quick

I'm on the "3D Printing South Africa" group - I saw someone else had issues, and Bernard did respond last night to try slow the fan down - it didn't work.

I want to try the same print I was having issues with on the other PLA, if its fine - I can then be fairly certain its the PLA and not me (the benchie failure I just had might have been the settings I had to try and see how it came out - it looked perfect, but pulled apart as soon as I tried to take it off, in comparison - I tried breaking the sample pla benchie, and its fairly solid)

Found it - thanks, I'll drop him a message directly.

(I actually ordered on the 27th of Nov - so maybe I got a bad patch).

I'm keen to try their SA Filament - seems a great price for basic colours, but - a bit concerned ordering 3x spools and its not great.

That was quick - they've offered to replace it if I don't come right, recommended 220 and 50% fan speed - so going to try that with a benchy.

It seems to only be an issue with the finer prints - the octopus I printed seems fine, the finer prints, like the benchy, and others - it seems brittle.

Anyways, going to order some of the SA Filament PLA from them... so hopefully I'll be back to normal printing in the next week or two.

Awesome!

AMS is really good,

I like the video you posted with the colour changing, definitely need to get some of that

It works well... It printed white, and stayed white for a few hours, the next morning it was the reddish/pink colour.

Hi. Don't know if this is the best place to ask it but, I'm looking to by either a laser engraver / cutter or a CNC Router.
Can anyone give me advice?
Which is a good one but not to expensive.

3dprintingstore.co.za , cron craft would be a good starting point

I got one a few weeks ago, with a laser attachment , the laser has been fun, but need to start with the routing stuff now

 

[nelca]

Which one did you get. How strong is the laser?
Can the laser cut thin wood?

Struggling to get my VPN up and running again... So in the meantime I can only watch via home-assistant, and hope nothing goes wrong.

Trying out octoprint, so far, so good - no need to move the microsd card back and forth.

What would cause these bubbles? Sometimes happens - other times not - same temps

What material is that? With some materials if the retraction setting is low (and sometimes it needs to be low) the material will heat up in the nozzle and flow out while the nozzle is moving.

Can try increase retraction.

Or reduce the extrusion from 100% to 90 - 95% so that a touch less material is coming out which could reduce buildup in the nozzle and the subsequent purging of material you're seeing there.

Might be another fix depending on the material or your specific printer.

Its PLA on a Ender3... just a bit stumped on how it only happens occasionally (twice so far)
