Glue For PLA+ and Others

It seems anything shipped to Canada these days requires a mortgage. Even Amazon Prime adds on to the cost of items compared to other sources.

The other problem we run into is some provinces appear to class that glue as hazard-is material and you know what that does to shipping.

I have a local source for the zap and a couple of other brands and I only need it for a couple of small projects so I won't fret about it. Worse comes to worse, I can print in something that acetone will de-solve and make a slurry and use it as a glue.

Quote from: wagnmkrthat glue as hazard-is materia

Weld-on #4 is a mixture of rather nasty solvents, and it is intended for gluing acrylics and similar. (I have some, very tightly sealed  )

I would look for anything local that says it is intended for "welding" acrylics or other plastics. It probably needs to actually dissolve the material to be effective.

A lot of glues don't work that way.

Also a recently converted RC glider /DLG guy (from Alberta). How's that 399'AGL working out, are we having fun yet? LOL (I digress). I just got a Bambu A1 couple weeks ago, First 3DP for me so still  novice but now really enjoying making my own stuff. I bought a reel of PLA from the outfit that supplied the printer so I can't even say what it is. He re-packages but says it prints well so good enough for me to get going. I'm pretty sure its not PLA 'plus', at least it doesn't indicate that anywhere.

With my scrap parts I've been playing with adhesives & spot fillers & primers. I'm actually very impressed because whatever 3DP parts I had before were very off-standish to many common shop materials. Kind of that shiny, Teflon-y 'don't stick to me' kind of material. This PLA is quite impervious to methanol, paint thinners & a few other solvents in my arsenal. Acetone will indicate some of the material color on a Q-tip swab so that appears more active. First thing I tried was CA with/without kicker & dang, it hung on surprisingly well. I jus roughed it with 120# paper & gave a wipe with methanol. I have not yet put the pliers on it to shear the glue so TBC.

I looked at the recommended glue a few posts up. It is available in Canuckistan. A bit spendy but at least no no import/hazop issues. I hope you try it so I don't have to gamble 31CAD haha. Now I wonder if some of the plastic plumbing adhesives might work? There are some common material crossovers between the 2 descriptions. Unfortunatly dont have any to try but its cheaper on volumetric basis (albeit differnt viscosity & other factors).

Petertha, did you perhaps get your Bambu A1 from Spool 3D in Calgary? I have dealt with them for a long time. They carry one of the Weld-On products there.

I might get a chance today to test what I have.

Yes, exactly. Spool3D. I just did a quick search under 'glue' & 'adhesive' on the website, but unless I missed it, only saw bed adhesive & general purpose glue we are familiar with in RC. Maybe that was Calgary specific.

Also on my list of glues to try from the shop arsenal is black (toughened) CA glue which I find to be particularly good on composites. And also a new purchase, some higher viscosity clear (I believe urethane based) glue which has worked well on tough to bond plastics where epoxy was cracking off and/or yellowing over time. Now would I trust these with 100% confidence in a structural / heat / vibration environment? Probably not, but I now see why say the plastic model or train crowd uses CA & doesn't bat an eye. At least on this type of PLA.

Sorry for subject detour, but while I was at an autobody supply store, I bought some of this 1K fine grain spot putty. Had not heard of the brand before because I have been out of that loop. But the spec sheet indicated a wide range of acceptable materials including 'plastics' which only narrows it down to about 10,000 varietals haha. The plan is some 3DP's will become male shape forms for female molds. I need to unload camera pics but I am very impressed with the prelim results. One swipe across the bed surface just using a playing card spreader filled in all the valleys only showing the tops of hills. A slightly thicker (or maximum 2 coats) across some more gnarly striated surface filled it very well. At least where a primer would take over which is the plan. Sanding & re-coats was dead easy & predictable. I cant recall cure time because I was done for the day & sanded in the morning. It had a slight odor but not as strong as classic polyester based bondo with catalyst. So TBC on that front.

Aha! Cheaper than Amazon. Thanks for link

Don't forget there may be a hefty delivery charge from Alberta to Ontario for Tom or other Ontarians. Just a reminder. 

I was going to order some with a new printer so it would be free delivery but ordinarily it would come priority mail at around the $14.00 mark for delivery. I have dealt with this company for 8 or 10 years and they are very reliable. I have had to phone a couple of times for help and they were very quick and knowledgeable about their products.

Good to hear, Tom. 

On the shipping front, so far been very happy with NetParcel within the CDN arena. You just enter minimal specs, it quotes out a list of price + delivery time options from low to high. Click one & print the shipping label. A lot of the courier based drop-off depots are your local neighborhood bricks & mortar stores making some side cash to hold the parcel for the delivery truck. Some will come to your door (have not explored that). CP is just one of many options. I have yet to find an example where it wasn't cheaper or faster than CP. Same tracking & insurance features. Free to make account. (Not endorsed just a new happy customer). I'm not sure its optimal for international but I have other modes for that.

Now that I have stopped spinning and weaving, I get very few deliveries. With a Great Hobbies store about 40minutes away that sells all the Creality machines and a couple of brands of filament, plus any other hobby I could care to play with, and Spool 3D orders 3 to 5 days away, that is all I need. I used to use Amazon a lot but their "free shipping" has added to their prices and the last two orders last fall went to the wrong house. Yes, it got sorted but I prefer not to have the hassle.

I am printing some small pieces at the moment that I will use to try out the Zap glue on.

The PLA I have sands quite predictably. I'm not talking remove a lot, but take the gloss & shine off the print. Under a microscope I'm visualizing it would be matte 'carpet' & could only assist with CA bonding. I'm keeping my 3DP rejects for tests like these. I has opened up a new world of potential for me, even if confined to prototyping things that take a lot more time in metal.

I'm happy to say that the Zap medium has worked a treat and the clock segments are now one piece. I will let them sit overnight to cure more and hope to carry on with the clock tomorrow.

Excellent!
