Vår CNC laser kan både kutte og gravere.
Maskinen kan kutte materialer som trevirke, papir, kork, metall, og noen typer plastikk.
Gravering kan gjøres på nesten alle typer materialer som for eksempel: trevirke, kartong, aluminium, rustfritt stål, plastikk, stein, fliser og glass.
Alle materialer som skal benyttes på laseren, må kjøpes igjennom DalaMakers, dette for at vi skal være sikre på at det ikke kuttes materialer som kan generere dødelige gasser!
The laser can cut or etch. The materials that the laser can cut materials like wood, paper, cork, and some kinds of plastics. Etching can be done on almost anything, wood, cardboard, aluminum, stainless steel, plastic, marble, stone, tile, and glass.
|Many woods||12 mm||Avoid oily/resinous woods||Be very careful about cutting oily woods, or very resinous woods as they also may catch fire.|
|Plywood/Composite woods||12 mm||These contain glue, and may not laser cut as well as solid wood.|
|MDF/Engineered woods||12 mm||These are okay to use but may experience a higher amount of charring when cut.|
|Paper, card stock||Tynn||Cuts very well on the laser cutter, and also very quickly.|
|Cardboard, carton||Tykkere||Cuts well but may catch fire.||Watch for fire.|
|Cork||12 mm||Cuts nicely, but the quality of the cut depends on the thickness and quality of the cork. Engineered cork has a lot of glue in it, and may not cut as well.||Avoid thicker cork.|
|Acrylic/Lucite/Plexiglas/PMMA||12 mm||Cuts extremely well leaving a beautifully polished edge.|
|Thin Polycarbonate Sheeting (<1mm)||<1mm||Very thin polycarbonate can be cut, but tends to discolor badly. Extremely thin sheets (0.5mm and less) may cut with yellowed/discolored edges. Polycarbonate absorbs IR strongly, and is a poor material to use in the laser cutter.||Watch for smoking/burning|
|Delrin (POM)||Tynn||Delrin comes in a number of shore strengths (hardness) and the harder Delrin tends to work better. Great for gears!|
|Kapton tape (Polyimide)||3 mm||Works well, in thin sheets and strips like tape.|
|Mylar||3 mm||Works well if it's thin. Thick mylar has a tendency to warp, bubble, and curl||Gold coated mylar will not work.|
|Solid Styrene||3 mm||Smokes a lot when cut, but can be cut.||Keep it thin.|
|Depron foam||12 mm||Used a lot for hobby, RC aircraft, architectural models, and toys. 1/4" cuts nicely, with a smooth edge.||Must be constantly monitored.|
|Gator foam||Foam core gets burned and eaten away compared to the top and bottom hard paper shell.||Not a fantastic thing to cut, but it can be cut if watched.|
|Cloth/felt/hemp/cotton||They all cut well. Our lasers can be used in lace-making.||Not plastic coated or impregnated cloth!|
|Leather/Suede||4-5 mm||Leather is very hard to cut, but can be if it's thinner than a belt (call it 1/8"). Our "Advanced" laser training class covers this.||Real leather only! Not 'pleather' or other imitations .. they are made of PVC.|
|Magnetic Sheet||Cuts beautifully|
|NON-CHLORINE-containing rubber||Fine for cutting.||Beware chlorine-containing rubber!|
|Teflon (PTFE)||Tynn||Cuts OK in thin sheets. See https://www.ulsinc.com/materials/teflon ; the issues listed in https://en.wikipedia.org/wiki/Polymer_fume_fever should not matter because our lasers are fully vented and exhausted.|
|Carbon fiber mats/weave that has not had epoxy applied||Can be cut, very slowly.||You must not cut carbon fiber that has been coated!!|
|Coroplast ('corrugated plastic')||12 mm||Difficult because of the vertical strips. Three passes at 80% power, 7% speed, and it will be slightly connected still at the bottom from the vertical strips.|
|Glass||Green seems to work best...looks sandblasted.||Both flat glass and cylindrical glass can be engraved as we have rotary device.|
|Anodized aluminum||Vaporizes the anodization away.|
|Painted/coated metals||Vaporizes the paint away.|
|Stone, Marble, Granite, Soapstone, Onyx.||Gets a white "textured" look when etched.||100% power, 50% speed or less works well for etching.|
Cermark is the brand name of a marking compound containing molybdenum that costs ~$50-100 for a 12oz spray can, which can be sprayed onto stainless steel, brass, aluminum, copper, nickel, glass or light-colored stone/tile before being etched to leave behind a permanent dark black mark. Some people have had some luck using dry moly lube spray to the same effect. It is thought that the molybdenum sulfate in the dry lube breaks down to molybdenum which either oxidizes or reacts with the underlying surface to create the mark.
Eksempler på materialer som IKKE kan benyttes:[rediger]
|PVC (Poly Vinyl Chloride)/vinyl/ pleather/artificial leather||Avgir klorgass når det kuttes||Don't ever cut this material as it will ruin the optics, causes the metal of the machine to corrode as chlorine is released and ruins the motion control system.|
|Thick ( >1mm ) Polycarbonate/ Lexan||Cuts very poorly, discolors, catches fire||Polycarbonate is often found as flat, sheet material. The window of the laser cutter is made of Polycarbonate because polycarbonate strongly absorbs infrared radiation! This is the frequency of light the laser cutter uses to cut materials, so it is very ineffective at cutting polycarbonate. Polycarbonate is a poor choice for laser cutting. It creates long stringy clouds of soot that float up, ruin the optics and mess up the machine.|
|ABS||Melts / Cyanide||ABS does not cut well in a laser cutter. It tends to melt rather than vaporize, and has a higher chance of catching on fire and leaving behind melted gooey deposits on the vector cutting grid. It also does not engrave well (again, tends to melt). Cutting ABS plastic emits hydrogen cyanide, which is unsafe at any concentration.|
|HDPE/milk bottle plastic||Catches fire and melts||It melts. It gets gooey. It catches fire. Don't use it.|
|PolyStyrene Foam||Catches fire||It catches fire quickly, burns rapidly, it melts, and only thin pieces cut. This is the #1 material that causes laser fires!!!|
|PolyPropylene Foam||Catches fire||Like PolyStyrene, it melts, catches fire, and the melted drops continue to burn and turn into rock-hard drips and pebbles.|
|Epoxy||burn / smoke||Epoxy is an aliphatic resin, strongly cross-linked carbon chains. A CO2 laser can't cut it, and the resulting burned mess creates toxic fumes ( like cyanide! ). Items coated in Epoxy, or cast Epoxy resins must not be used in the laser cutter. ( see Fiberglass )|
|Fiberglass||Emits fumes||It's a mix of two materials that cant' be cut. Glass (etch, no cut) and epoxy resin (fumes)|
|Coated Carbon Fiber||Emits noxious fumes||A mix of two materials. Thin carbon fiber mat can be cut, with some fraying - but not when coated.|
|Any foodstuff ( such as meat, seaweed 'nori' sheets, cookie dough, bread, tortillas... )||The laser is not designed to cut food, and people cut things that create poisonous/noxious substances such as wood smoke and acrylic smoke.||If you want to cut foodstuffs, consider sponsoring a food-only laser cutter for the space that is kept as clean as a commercial kitchen would require.|
