What is 3DLAC. Personal experience of use.

How does 3DLAC work?

After application, 3DLAC forms a thin sticky layer on the surface of the plate. When heated (usually within 60–110°C), this layer activates and provides reliable adhesion of the first layer of filament to the plate. After printing is complete and the platform cools down (below approximately 30°C), the adhesion weakens, and the model can be easily separated without tools or damage.

Usage Instructions

• Remove any remnants of the previous print. I usually wash the plate with regular water.
• Make sure the surface is completely dry and clean.

• Shake the bottle well before application (5–10 seconds).

• Spray from a distance of 20–30 cm. I usually go over the entire area twice — this is usually sufficient.
• Apply evenly, without excess.

• Start the print. As the plate heats up, 3DLAC will start to work — providing reliable adhesion of the first layer.

• Wait for the plate to cool completely.
• The model easily comes off by itself or with slight effort. I sometimes slightly bend the plate to help the parts separate faster — I'm not sure how correct this is, but it works for me.

Cleaning and Reusing

• It is not necessary to wash the plate after every print. It doesn't make sense.
• According to the official instructions, it is enough to apply a little spray to the area where the previous parts were (white marks remain on the plate — they will indicate where to spray).
• I wash the plate after approximately 0.5–2 kg of printed filament. Especially if there is noticeable dust, dirt, or hair.
• If you accidentally touch the plate with your finger — it's not a big deal, 3DLAC usually handles it.

How to know when it's time to wash the plate?

• I check visually: if there is dust, lint, or plastic hairs stuck — I wash it.
• If the surface seems fine for printing — I continue printing.

Works very well with PETG.

How long does it last?

Currently, I have printed about 35 kg in total on the printer. I'm finishing the second can (400ml). The price is not very low (~10-12 dollars), but considering that there are no adhesion problems (with PETG) now and I don't have to constantly spend time washing the plate - it's quite good.

Taking into account the calculation errors in usage, it can be confidently said that 1 can (400ml) lasts for 15+ kg of PETG.

Now I don't have this at all:
