Product Information

However, while the foam will engrave, there may not be a sufficient contrast in colour between the normal and engraved surface. What Settings Should I Use To Laser Engrave Foam? Soft and foam-like material that is very easy to work with - easy to cut with scissors and to punch out to make a massive array of crafts. Ideal for children's craft and perfect for Halloween, Christmas, Valentine and Easter craft projects Layer 1 had a 32 x 8mm cut out, but I reduced the power by half so that it did not cut all the way through. The interior material was easily removed. What happens if you use cold water to make up the yeast solution instead of warm? How will you measure this? Why does this happen?

Pour sufficient (20ml) washing up liquid into a Gratnells mini-tray or 50ml beaker and leave aside until needed. You do not need a lot of laser power to laser engrave. My typical go to laser engraving settings on my 50W laser is 20% power (about 18 Watts), 400mm/s and a scan interval of 0.2mm. It will of course vary on your machine set-up, but it’s a good place to start.

A hole cut – this is where the external measurement is the important parameter and the inner material is disposed of. Layer 6 had the 32 x 8mm slot and a 26mm diameter hole removed. Similar to the London Underground logo.

Swirl to mix the reagents, or stir each test tube with a glass stirring rod in turn (Tip: Work from lightest colour, yellow, through to darkest colour, blue, with your stirring rod to enable you to use the same rod). Draw around an egg cup on the yellow funky foam or cardboard – he discovered that you don’t actually need to do this for the foam, you can just press down and the egg cup leaves a print Using a plastic pipettor, add 3ml washing up liquid to each large test tube (already containing the 25ml hydrogen peroxide).

How could this reaction be made faster and more spectacular? Tip: Look up spectacular elephant’s toothpaste demonstrations on YouTube. When cutting any new material, but especially plastic based materials. You must make sure you know exactly what you are cutting, get a technical specification whenever possible.

Assuming you have either a Polyethylene (PE) Foam, Polyurethane (PUR) foam or a Polyester (PES) Foam set up a 25mm test square on your laser software of choice and choose the dot mode or equivalent laser processing mode. You may as well start with the settings I ended up with and adjust from there. Remember; Once the reaction has finished the 6% Hydrogen Peroxide will have fully decomposed. The contents of the test tubes can be disposed of in the sink using plenty of water. Now that you know how to laser cut foam, this next post will show you the best way to utilise your new skills and teach you how to Laser Cut Foam Inserts For Tool Boxes using the toolKaiser App Can You Laser Engrave Pink Insulation Foam? A plug cut – this is where the inner measurement is the important parameter and the inner material is the desired component.Use the longest focal length lens you have; 2.5″ or 4″ is best, but you can still cut with a 2″ lens if that is all you have. I know Easter is a while off yet but we were in the mood for a bit of Springtime at the weekend and an Easter craft seemed to fit the bill (pun intended). In the 100ml beaker, make up a yeast solution by adding 7g dried yeast into 60ml warm tap water. Give it a good stir and leave aside until needed. Tip: Only make the yeast solution when you are ready to complete the rest of the experiment as it needs to be fresh.

Having the nozzle closer to the work piece, makes the air assist more effective, however in most set-ups this means the laser beam will be focussed below the surface, giving a larger kerf or cutting width at the top surface. Using a clean plastic pipettor, add 3ml yeast solution to each of the large test tubes and observe the reaction. Foam in five different colours should travel up the sides of the test tube, over the top and down the sides into the tray.

Seal: Closed cutting graphics does not require the use of sealing compensation, but un-closed graphics can be closed by means of it. If, however, the sealing is misplaced, there will be no compensation. Enter a distance, in the seal box, that if the un-closed distance is less than, then sealing is desired. Seal defines the overlap of beginning & end of the cut. This is an exothermic reaction (produces heat). The oxygen released during the reaction is trapped into bubbles by the washing up liquid, which are forced out of the top of the test tube in a cascade of coloured funky foam. Other things to try… Sew Compensation (Kerf Settings): A kerf is the width of the cut made by the laser. By default RDWorks cuts along the centre of the path. This will result in outside cuts being smaller, and inside cuts being larger. The kerf settings allow you to correct for this. My Laser Power Meter Project
