Questions about Clear Acrylic Sheet - Cast

Cast sheets good for use in laser cutters


Will these sheets come with a masking?

Asked by Inventables on Apr 18, 2011

The acrylic sheets come with the following masking:

  • Opaque, translucent, transparent, and fluorescent acrylic sheets come with paper masking.
  • Mirrored acrylic sheets come with poly masking on the mirrored side, no masking on back side.
  • The one-sided matte acrylic sheets and the Ice Blue Acrylic Sheet have paper masking on one side and poly masking on the other side.
  • Clear acrylic sheets can have either paper or poly masking depending on what brand we currently have in stock from our supplier.

What is the difference between acrylic, Plexiglas, Lucite, Perspex, and Lexan or clear plastic?

Asked by Inventables on Oct 31, 2011

Acrylic (polyacrylate) is marketed under many trade names including Plexiglas, Lucite, Perspex, Policril, Gavrieli, Vitroflex, Limacryl, R-Cast, Per-Clax, Plazcryl, Acrylex, Acrylite, Acrylplast, Altuglas, Polycast, Oroglass, Optix.

These differ from Lexan which is polycarbonate, and is sometimes used as bullet-proof glass. Although it is more shatter-resistant, it is more expensive than acrylic, yellows with prolonged exposure to sunlight, and is much more easily scratched. Therefore acrylic is more ideal for most interior and exterior design purposes.

Is it possible to buy 6" square clear acrylic panels

Asked by Carolyn Harding on Nov 8, 2011

Yes, but you are subject to ordering a 4×8 ft sheet and having it custom cut into 6″ × 6″ squares.

Answered by Philip Lomac Inventables on Feb 28, 2012

Yes, you can buy 6" acrylic squares from several online sources. Here is one source that offers thicknesses from 1/16" to 12", and will custom cut to size and polish if desired:

Is is possible to bend the acrylic sheets?

Asked by Jon Schilling on Jan 24, 2012

Hi Jon, Most Acrylic can be cold formed. A minimum radius of 200 times the thickness of the acrylic is required to avoid stress cracking. Acrylic can also be bent using a technique called Line Bending which is a method of forming a sharp bend in the acrylic sheet. The radius of the bend can be controlled by adjusting the width of the heated area. Routing a V-groove into the acrylic prior to bending will produce a very sharp bend. Heating elements such as nicrome wire, infrared, rods, or wide strips can be used. Heat the area to be bent to a pliable state then place the sheet in a fixture to cool. Thirdly you can thermoform where the acrylic sheet is heated to its forming temperature, placed over a mold, creating an air-tight seal. Vacuum is drawn through the mold, pulling the sheet to it. Once the part takes the shape of the mold, it is slowly cooled, then released. Bending specs should be reviewed for each brand of acrylic as they might vary slightly from brand to brand.

Do you know if any of this acrylic can be used to make a small fish tank?

Asked by Dan Gregson on Aug 10, 2012

Hi Dan, yes aquariums are often made with acrylic. Advantages are that you can shape it and they are lighter weight than glass. One disadvantage to consider is that the acrylic might show scratches easily when you go to clean the tank with a material like a rough algae pad.

How stable would it be to glue two end pieces together?

Essentially stacking the acrylic on top of each other (not face to face, but edge to edge) using the 1/4 thickness.

Asked by Martin Tomaj on Mar 24, 2014

Hello Martin,

The stability would depend on the size of the material. If you use a glue like Weld-on, it creates a strong chemical bond. However, depending on the size and application of the joined materials, they could be subject to breaking the seems. I would recommend testing this process for your application.

CNC milling of acrylic

I plan on milling some small parts of clear acrylic on my ShapeOko 2. What would you recommend the speed be on the quiet spindle, the feed rate and the depth of cut be to get the best results?

Asked by Stephen Halasz on Oct 24, 2014

Hi Stephen,

I would recommend starting with the default acrylic settings in Easel. A depth per pass of 0.020 in and a feed rate of 25 in/min. If that works well, you can play with increasing the depth per pass in increments of .005.

What is the minimum bend radius needed to avoid permanently deforming the sheet?

I need to be able to roll up a (very large) sheet of acrylic (for transportation purposes and moving around parts of a building). The sheet must then be flattened when I have finished moving it around. I do not want to permanently deform the sheet of acrylic. I currently use polycarbonate but would like to switch to acrylic. So please let me know how much I can bend it as a function of the thickness of the sheet. Thanks

Asked by Bob on May 19, 2015

Acrylic plastic does not roll up. Even the thinest acrylic will not be able to roll into a cylinder. A polycarbonate would be better suited for that application.

Heat bonding

If after gluing pieces of acrylic together can you use an annealing process to obtain one piece ie want to make a rainbow multi colours
Thanks

Asked by Peter on Jun 16, 2015

My understanding is annealing acrylic will reduce internal stresses from fabrication. Annealing results in greater dimensional stability and greater resistance to crazing. While these mechanical properties improve I am not familiar with a way to make a rainbow multi colors with clear acrylic using annealing.

Looking for thinner cast acrylic sheets in a variety of colors

Would like to buy a selection of colors of thinner cast acrylic sheets, 2mm thick, or about .08 inches. Would need transparent colors. Hoping for light blue, violet, yellow, amber or orange, and a very see-through red and green. We would only need perhaps a 2′ × 2′ piece of each, or maybe 2′ × 3′. The material will be cut with a co2 laser. Ideally paper backed, or without backing. Is it possible to get this thickness in these colors? would also like quote for clear and smoke-tinted in that thickness (2mm or .08") Thanks! We need this for cutting a lot of small pieces for art projects – the material does not need to support weight, and the pieces we use are about 2" wide at most, but we need a fair number of them, if this helps. The tolerance on thickness does not have to be super-exact. We are told that the laser cutting requires the cast, not extruded type acrylic. Hope you can help!

Asked by Kerin M Schiesser on Aug 9, 2016

Hi Kerin, thanks for contacting us. The availability of acrylic can vary widely based on color and production method. Generally cast sheets will start out at .125" at least with American suppliers. You may have better luck with Alibaba, particularly for metric thicknesses. As far as the sheet sizes you’re looking for, we don’t really offer them since we get everything pre-cut from master sheets, but a supplier like E&T Plastics may be able to sell you larger custom sizes or at least master sheets. Both cast and extruded acrylic can be cut with a laser, though cast acrylic tends to cut a bit cleaner and gives a nice ‘frosted’ effect when engraved and is generally a stronger material.

Thickness vs stability

I need to do some fine cutting and complex engraving on very thin stock… think small toy pieces with lots of negative space. Is it too hopeful to assume that 1/32" can survive this without deforming from the heat? I’m going to be laminating multiple pieces together so maintaining planar stability is pretty important.

Asked by Nathaniel Ellis on Nov 1, 2016

Hi Nathaniel, because the sheet is so thin, there is some danger of it warping as it’s cut, though depending on the method used your results may vary. If you’ll be milling, you’ll just want to make sure to hold it down with something like double stick tape and have the feed rate fast enough that it doesn’t melt the plastic to the bit or itself. If you’re working with a laser, you’ll probably just have to play around with your settings until you get something that works. Please let us know if you have any other questions. Best, -Griffin.

Thanks Griffen for answering my question. About the door sag? If I used two big hinges and when the door is closed I used two decent latches do I still need to be concerned about door sag ? I was more afraid of warping due to humidity of the vivarium I’m hoping the 3/4 Inch thick piece would be OK. Thanks John

Asked by John Pisano on Feb 9, 2017

Hi John, the Acrylic should be more or less impervious to humidity, though prolonged exposure to heat will cause issues. Unfortunately we usually deal with this material in decorative applications and are less familiar with its structural properties. I would get in touch with someone more familiar with using acrylic for structures. I would think that a supportive metal frame with thinner (~1/4") material might be a bit more practical than 4′×4′X3/4" sheet (which will weigh around 63lbs) Please let us know if you ahve any other questions.

Vacuuming forming 1/4" clear acrylic at home

Hi I’m trying to make a clear acrylic funnel that is 34" long, 14" diameter at the top and 5.5" wide at the bottom. It is going to be used to shrink wrap something. It will be in two halves that bolt together around the item to be shrink wrapped. I made a wooden mould on a lathe. I bought some plexiglass and tried to use a heat gun to wrap it around the mould but that is definitely not happening. I read online that I need to use extruded acrylic. I wanted to use 1/4" thick acrylic, is it possible for me to build a vacuum form setup at home that is powerful enough to bend 1/4" acrylic? How big a sheet of acrylic would I need if the wood mold is 34" long, 14" wide at the widest, 5.5" wide at the narrowest, and 7" tall?

Extruded acrylic will generally be more forgiving, though there would likely be difficulties getting even heating, accurate molding, etc. Something like thinner ABS may be more practical. Unfortunately vacuum forming is not our area of expertise, so it might be worth talking with a company that does this professionally. They could probably give you a better idea of materials requirements, etc. Have you considered using the wooden mold to lay up fiberglass w/ epoxy or other resin? This is, of course, a bit of a dark art unto itself, though it may be more practical if you’ll just be doing a few of these molds. Please let us know if you have any other questions. Best, -Griffin.

Acrylic - cracking

I am finding that when I laser cut my acrylics they are cracking around the edges. Which type of acrylic is less likely to do this and could the backing being left on or off make a difference?

Asked by ella goodwin on Mar 10, 2017

Hello Ella,

I am sorry to hear that you are having trouble with your acrylic sheets. Generally, extruded acrylic sheets are more prone to stress cracking when lasered. Cleaning the acrylic with some sort of solvent after a cut may cause cracks as well. That being said, I would recommend using the cast acrylic sheets for future projects, as they are less likely to crack.

I hope this helps!

Do you have a clear acrylic sheet transparent to UV light (at least from 355 or 360nm)?

I am a research intern, I want to use a clear acrylic sheet for an experiment but it has to be transparent to UV light, at least from 350nm. Ideally thickness would be under 1/8".

Asked by Jean Fatien on Apr 4, 2017

Hi Jean, thanks for contacting us. Unfortunately we don’t have data for the UV transmission on these materials. It will likely vary between the cast and extruded sheets. It’s probably best to purchase a sheet and test the UV transmission in a controlled setting. If precision is needed, it might be best to go with a glass element. Please let us know if you have any other questions. Best, -Griffin.

CNC Milling Perspex

Is there anyway CNC mill clear perspex and keep the same or near clarity of clear perspex. Also if i wanted to join multiple clear sheets together how would i do this without disrupting the clarity of all the sheets.

Asked by Nathan Dunn on Jan 23, 2019

Unfortunately you will likely always have some type of artifact from the carving process preventing near clarity when milling. You might consider using a laser cutter as that will leave a polished edge. Using a solvent-based cement would be the most appropriate when joining two pieces of material, and here’s a great Make article that has more information.

Asked by Carrie on Feb 6, 2019

Hi Carrie, you can use masking film or paper to wrap up the aquarium tank to prevent scratches. A layer of bubble wrap would work well over it, in case the tank is dropped during transit. If any scratches do occur, you can clean the acrylic with a plastic cleaner, such as this one: https://www.amazon.com/NOVUS-PC-10-Plastic-Clean-Shine/dp/B002UD0GFE?th=1

gluing a 24"x48" plexiglas on slider door glass

I am making a diy faux stained glass project on 24″×48″ × 1/4" plexiglas panels and want to eventually glue it on or hang it on sliding door panels. whichever is the best way how do i do either. (glue or hang) on sliding door panels are 32″×72″

Asked by Mayet Mendoza on Jun 29, 2019

Hi Mayet, whether you hang the acrylic or use glue entirely depends on your preference. Either one could work. If you want to adhere the acrylic to glass, a silicone caulk would be best. For hanging, standoffs would be the easiest solution.

Asked by Anas Ahmad on Jun 30, 2019

Hi Anas, if you’re trying to determine the difference between cast and extruded acrylic, this may be helpful: https://www.acmeplastics.com/cast-vs-extruded

If you’re using the acrylic on a laser cutter, you can try running a test engraving. Cast acrylic will give you clear, defined lines and extruded will look softer.

How to edge glue 1/4 inch to 1/8 inch acrylic

I have two different thicknesses of acrylic that I’m edge gluing as the sides of a large trunk. the longer face sheet is 1/8 inch thick while the shorter pieces composing the sides (depth) of the trunk are 1/4 inch thick. I’m thinking this should be fine given the way in which plexiglass “welds” together but my question is: which end should I apply the solvent to (I’m planning to use SCIGRIP 16) the ends of the 1/4" piece or the ends of the 1/8" piece. I’m thinking that applying to the 1/4 inch piece would provide more surface area, therefore greater adhesion but I feel as though the other way around would provide a better aesthetic appearance as I would be able to polish the ends of the 1/4 inch pieces which face the front of the trunk (to my understanding gluing polished edges is very difficult). Thanks!

Asked by Nick Anthony on Dec 20, 2020

Hi Nick, thanks for reaching out. It’s difficult for me to say for sure without visually seeing what the project should look like in the end, but I would recommend applying the glue to the 1/8" piece if appearance is the most important to you. Acrylic glue causes a chemical reaction that bonds the two pieces of acrylic together, so a strong bond should still be formed. However, if this is a part where strength is important, such as a load bearing part, you may instead want to apply the glue to the 1/4" piece to increase the surface area. I hope this is helpful!

Labeled for laser cutting?

My school requires that all acrylic is labeled as safe for laser cutting. Specifically, they state:
“We will not cut any acrylic which can not be identified. It must have the original manufacturer’s identification or “Laser Friendly” label from the supplier"
Do all of your acrylic sheets meet this requirement?

Asked by peter baldwin on Jan 16, 2021

Can multiple sheets of acrylic be stacked and cut together on a laser cutter?

I’m looking at having some relatively large pieces (~150 inch perimeter) cut from 1/4" acrylic. To save on cutting costs, I want to know if I can stack 4 or 8 or more and have them all cut in one pass. Obviously it depends on the power of the laser to a certain degree, but assuming the power is 4000W…something that can cut 3/4 steel… Previously I’ve been charged by the linear inches being cut as well as by the hour. So if it’s by the linear inches I thought I could have them stacked and cut more slowly and if its hourly, one at a time…and just run at high speed. Thanks!

Asked by Aaron James on Feb 14, 2021

Hi Aaron,

Thank you for your question.

There are a couple of things to consider when using a laser cutter for acrylic. Since you are using heat to cut the material, stacking it can cause the material to fuse together. Additionally, most lasers can cut accurately through 1/4 inch or maybe 1/2 inch thick material. Since the laser is focused to the top of the material, the cut will become inconsistent with anything much thicker than that, on most lasers. You will start to see diagonal cuts, which will lead to inconsistently shaped parts. It could also be a fire hazard, heat may become trapped between the layers of acrylic.

My suggestion would be to reach out to the company that is doing your machining to see what they suggest and what they are willing to do.

Hope this helps!
