From 3D-Print to Concrete - DIY Silicone Mold Making Process

[@RoseKindred]

As someone who tried to get into candle making, that wick length guide for wooden wicks is a nice print. Well done. I have done similar with mold making and even my own placement, but never thought to make that guide.

[@ben5235]

This was aesthetic as hell, smooth

[@danilaalpatov1374]

I have had a decent result printing the form directly from TPU. Not as soft and forgiving when demolding as silicone, but fast and convinient

[@antoniodettoli2845]

you've been really smart

[@reservoir_flow]

Well unless you know something about TPU smoothing and post-processing I don't, the layer lines would still show up on the final product no?

[@martinperezgarcia]

I do have the same concern about TPU and the layer lines… how are you dealing with that?

[@danilaalpatov1374]

@@reservoir_flow yes, there are layer lines. I have some thoughts on this matter 1) For some models, two-minute sanding after demoulding was more convinient than post-processing and painting the master-model itself. Concrete is very easy to sand, especially when its wet. 2) For other models, layer lines were not a problem given the crude and matte nature of the concrete itself. Natural concrete finish was enough to blend lines into surface 3) For some other cases, dropping layer height to 0.08 was more than enough to hide lines completely, especially concidering 2) Of course, that method is not for everyone and not for every case. But for me it was a relief, giving me an opportunity to iterate quick and cheap

I've been following your work on Instagram for a while now, and as someone who has been trying to figure this craft out too your iterations have truly been an inspiration for me! I have been loving how clean and precise your moulds are and the resulting casts look incredible. Thank you for sharing your processes and keep up the great work 👍

5:01 what a satisfying pop! Amazing video, loved watching the process!

[@wyattwolf8150]

Super nice! If you add even a small draft to the center hole like 1 degree it will make your mold release way easier! Not that it looked too difficult here to begin with

[@Diemermakes]

Prob worth doing. It'll likely give the mold a longer life if it's easier to demold. Less chance of destroying it

Nice!! I would make a Vibration Tool for the concrete to spread it better and let it vibrate for a couple of minutes. But great job!!

[@LaO2]

It's good idea!

[@needamuffin]

That "vibration tool" can just be a reciprocating saw or palm sander you touch to the side of the mould.

[@erhardpostinger1326]

@@needamuffin Für eine Säge müsste eine Untersetzung gebaut werden, weil deren Schwingungen zu stark sind. An Schwingschleifer habe ich auch schon gedacht, aber vielleicht taugt auch mein Ultraschallgerät (Brillenreinigung) ?

[@GerManBearPig]

You can buy flow additive / plasticizers which make vibration unnecessary. But usually the amount needs to be calculated with the amount of pure cement (only the binder, not the concrete mix with sand and gravel) which makes the correct dosage tricky unless you go for trial eland error

You have not sealed the plaster/concrete, the wax will be making oily patterns on walls and soaking into wall and deteriorate it. Use any varnish for plaster to seal it, make sure is fireproof varnish as well.

[@TheFlyBullet]

I guess if you put them on an vibrator plate after pouring or degas the material you might get rid of the minor surface defects 🤔

[@LaO2]

perhaps

[@JumpingCap771]

Why do you use the vacuum for the silicone? Tried to Google it but the answers are very differently

[@zero-coolpropshop1748]

The vacuum pressure causes the air bubbles to rise to the top and pop/release to create a bubble free surface.

[@needamuffin]

​@@zero-coolpropshop1748 Alternately, using a pressure pot makes the bubbles so small you can't see them. Opposite processes, same result.

[@Crypt1cmyst1c]

it removes bubbles that can cause voids. with resin, people can use either vac chambers or pressure pots, because resin cures solid, the pressure pot will shrink the bubbles really tiny and not be a problem, but in something flexible like silicone, those bubbles only shrink while it's under pressure. when you take it out of the pressure pot, the bubbles re-expand and can warp the mold. it's good to throw the entire mold in the vac chamber while the silicon mold cures too, it'll pull bubbles from the surface of the part, too.

[@LaO2]

check out my future vacuum chamber video, coming soon

[@eschersky]

[@petsworld2294]

Excellent workmanship. There is only one thing I am curious about. I saw that you have an SLA printer. When I place such products flat on the tray in the SLA printer, there are traces on the layers. Why is this happening? How do you solve it?

[@humphet3750]

Nice but *too* *much* bubbles for so simple model. Can use many methods to improve - vibration, pressure chamber, defoaming agents, etc

[@dyeazel]

To be clear, this is NOT concrete. This is cement. Concrete = cement + sand + gravel Mortar = cement + sand

[@tian1332]

some commentary for the process or subtitles narrating would be nice great concept tho

[@micah2936]

Why not skip the silicone and just print out a negative / the direct mold and pour the concrete into the PLA part?

[@needamuffin]

PLA moulds are much more difficult to reuse over and over. Having the mould be silicone also simplifies it because it can stretch around details like the flower on the front rather than having to have multipart moulds to get around them. You can also mostly ignore draft angles for the same reason.

[@micah2936]
