3D Printing is a Modern Family Hobby r/3Dprinting. This will leave your print surface smooth and dry (no longer sticky). Here’s the parts manifest: Helping hands or 60mm magnifying glass; 12 White LEDs Don’t make me measure that thing in centimetres or my head might explode. https://www.youtube.com/watch?v=x3NXvE6GcOU, Participated in the First Time Author Contest. Even with glasses, you may need a little help making out the fine print at times. If your enamel coat becomes contaminated or uneven. If you don’t have a dual extruder or you don’t want to go through the same process I did, you can always print each part individually and then glue the c0re and diffuser parts together, the result should be more or less the same. We have a huge range of Illustrations products available. I've had a few coated items next to bright windows for a few weeks with no noticeable deterioration or discoloration. Helpful. 14 day loan required to access EPUB and PDF files People can make glasses for a village! If you weren’t satisfied with my explanation, maybe this link can help, but I wouldn’t know as I haven’t even looked at it. Unfortunately printing with multiple materials presents some challenges which need to be overcome by either making a “dual colour friendly” design or making a large number of calibration prints to get the parameters exactly right. ( Log Out /  http://www.thingiverse.com/thing:1006913. Free 3D Models. 61 3D Magnifying glass models available for download. Spray enough coats until the surface of the print is smooth and optically clear. Instead, you can run LEDs in series; each provides a voltage drop and when the sum of the voltage drops matches your supply, you don’t need a current limiting resistor at all; the LED chain provides its own. Perhaps someone will find it usefull for something. Tip: The finer the layer height the less coats of enamel you will need to achieve the same clarity. The motivation for this project came when I was building my new dual extruder 3D printer (which I used to 3D print the models I will later show) and somehow managed to short out the fan pins and burn an SMD MOSFET. To create all the models I used Onshape which is a pretty cool 3D CAD modelling software which works pretty well on the browser. Once your 3D print is clean, go ahead and remove supports. Get it as soon as Wed, Jul 8. Lightly spray an even coat on one side of the print and then on the back side of the print. I love 3d printed lenses. I have never had any problems with sharps or getting cut. This will reduce layer visibility and greatly increase clarity of your lens. The material choice I went for was Clear Taulman T-Glase. If you’re interested in making your own magnifying arm, you can download the STL files and print them yourself. on Introduction. I also glued the breakout board to the core with some cyanoacrylate: The next step was to connect the arm and the lid using the original screw, at this point I must warn you that the screw I received on my Universal Holder Arm might be different to the one you’re using, so it might not be a perfect fit. Access to a SLA type (resin) 3D printer (Ex. So once I got past this particular bump on the road, I went ahead and created my next and final design, which included a solid diffuser and a much more compact lid, with the arm connection on the inside. The magnifying glass itself is good enough for the kind of soldering I do and it’s about 60mm in diameter which is also quite a decent size. 5.0 out of 5 stars For my use, it magnifies the designs beautifully! Report abuse. Impressive! As you can see on the following picture, the light diffusion is quite nice on clear T-Glase: Unfortunately, once I made the decision, I opened a small Pandora’s box of my own. The main reason for this is that I needed the PLA to be printed on top of the T-Glase as the other way around wouldn’t work due to the terrible adhesion when printing T-Glase on top of PLA. I used Simplify 3D to generate the G-Code and this is the resulting preview: Even though the print worked, it was certainly not an easy print. Since Simplify3D doesn’t provide a way to generate different parts of the brim with different materials and the adhesion between T-Glase and PLA is far from perfect, the prime pillar decided to make a run for it, resulting in a mess of spaghetti T-Glase. The end result should look as follows: The final and probably the most exciting step of the process is to connect the arm back to the pana-hand and connect the μUSB cable. If you used similar materials you should get a pretty decent light diffusion all the way to the centre of magnifying glass. on Introduction. Always hang dry the lens. Change ), You are commenting using your Twitter account. You can download the STL model of the magnifying glass I designed from thingiverse. Ensure your 3D print is free from uncured resin. The concept works! The enamel will dry to a clear finish once fully dried. You should be able to use any other 3D printer though. Fortunately for me Hobby Creek also makes a Universal Holder Arm which looked easy to disassemble so I bought one of those and basically removed the reusable zip-tie and kept the screw. The spray can itself has no UV protection details but looking at the Home Depot description it claims it does "Excellent UV protection for projects". Remove any contaminates or unevenness by wet sanding away using very fine sand paper (ex: 2000 grit). With a magnifying glass, you can easily catch the details that your normal vision is missing. Open the file in your 3D printing software and print out a copy. In my opinion Simplify3D is probably one of the best slicers out there, but I believe it still needs some work in order to support this type of prints. I could probably come up with a number of additions which would have helped, but the most important one I think would be the ability to print a brim on either the ooze shield or the prime pillar using the extruder assigned to each specific feature. However, industrial 3D printer operators are increasingly looking to glass as a reliable printing bed material. 33. The third design worked pretty well on every aspect: the size was just right, the LEDs and the magnifying glass fit really well, the connection between the LEDs was relatively easy to make and the diffuser (which was completely empty) worked pretty well. Unfortunately, at this point I came to the conclusion that white PLA for the diffuser was not the best idea as, even though it diffused pretty well.

This would not be as convenient to implement as powering from a USB cable. After I successfully managed to replace the transistor, my subconscious mind had already made the decision: I was going to make an illuminated magnifying glass arm! I did some digging through my old junk cupboard and found one of these ubiquitous helping hands with a magnifying glass on it and dismantled the damn thing. Commercial License Included. Or you can use your own design. In my case, you can see that the light towards the centre is quite uniform: If you used Taulman T-Glase but didn’t manage to get such a uniform light diffusion, you can try printing the part again increasing the nozzle size and reducing the temperature. According to Taulman, this will produce a clearer print with improved optical properties. Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. Don't try this at home, kids. Heading out to the desert and harnessing the power of the sun to make a 3D printer that can print objects out of sand. A lot of people also like to print a Benchy when testing a new brand or type of filament…you can easily end up … I also used a brim to increase the adhesion of both the ooze shield and the prime pillar. Find 10 listings related to 3d Systems Corp in Burlington on YP.com. * *Yes, yes, 3D printing uses the metric system and filament is measured by the grams and meters. Reply A magnifying glass is a convex lens that provides a magnified image. Available in any file format including FBX, OBJ, MAX, 3DS, C4D As mentioned before, I used blue PLA for the core and the lid, and Clear Taulman T-Glase for the diffuser. Zip-archive contains jpg and eps files. An illustration of a horizontal line over an up pointing arrow. What better way to test the optical clarity of Clear Resin than making a magnifying monocle?. The smoother this first surface the better quality your 3D print will be as this is the foundation of your entire print. Weighing 13 grams, you could crank out 153 of these 2 inch tall tops from a standard roll of PLA printer filament. ... but practical and easily understood introduction for any software engineer seeking to delight the consumer with rich 3D interactive experiences on their phone. Or you can use your own design. The final thing I needed which I didn’t already have or couldn’t 3D print was an arm to spare. On your iPhone or iPad, go to Settings > Accessibility. Read more. The second prototype was another failed idea, but it allowed me to understand how to better design the diffuser since the small diffuser was not very effective. What exciting developments await 3D printed optics? You can see the scars on the bottom and back. Do not over expose your print to UV light or your print will discolor and deteriorate. Fortunately, this madness was contained to the last two layers containing T-Glase. Imagination meets reality with the 3Doodler Create+ Juku 3-D printing pen. Yes, this project involves more than just 3D printing – it’s a real, functioning illuminated magnifying glass. I must admit I was lazy enough to use this calculator, but in fairness it does provide you with the closest resistor to the value you can actually buy, which is pretty handy. Magnifying glass 3D models. Since I have a Form1+ from Formlabs I used Preform as the software to print this model. If you think I’m exaggerating have a look (I cleared up some of the mess at this point, but it’s pretty descriptive): Since T-Glase doesn’t adhere to the kapton tape as well as some sources claim, I had to ramp up the temperature to 70º, which ultimately caused the PLA to warp a bit, although I must admit it’s not too bad: Printing the Lid was pretty much straightforward using the settings detailed before. … I believed I could find a better material for the job, and so I did. With all the decisions made and the models generated, it was time to get on with the 3D print and the build of the illuminated magnifying glass. Does it actually make the lenses as well! ( Log Out /  They have always fascinated me! You’ll need to wire up the LEDs and provide the actual magnifying glass as well as 3D printing the structural components. Engineer by day, Maker by night. You *cannot* use a single current-limiting resistor for multiple LEDs in parallel like that. Be careful not to cut your self. You can do this by swashing your print in alcohol. T-Glase is famous for being difficult to print with problems ranging from terrible overhangs, irregular extrusion, flimsy layer adhesion and, to make matters worse, T-Glase has very little adhesion to PLA, so the dual extrusion idea was going to be quite difficult. to Magnifying Glass… I use a Micro Soft Wire Cutter to remove supports. The electronics of this project are very simple, it is just an LED circuit with 12 LEDs in parallel and a current limiting resistor in series with the supply. If you can print a good Benchy then relax, because your printer is set up perfectly. In any case, I believe that white PLA with a hollow diffuser would have been good enough with sufficiently bright LEDs, so if you try it out yourself, let me know! Finally a note of caution, I might be wrong on my suggestions so if you want to be 100% sure of what you’re doing, you can probably find other resources online with much more accurate information. This will ensure your can is evenly mixed but not too agitated to introduce air bubbles on your print. If you want to buy any of the materials I used for this build you can use the following links, although I must warn you that the eBay and Amazon links are “affiliate” links and they provide me with a negligible amount of money. This includes not only this blog post but also the STL files which I have produced after many hours of work. If you would like to use my work for commercial purposes, please get in contact with me. patricia beall. Fortunately, PLA, the paragon of 3D printing materials, adheres just fine to T-Glase, which solved half of my problems. Scale the lens in your CAD program, using calipers or the width dimension stamped on your old frames. Tap Magnifier, then turn it on. The settings I used for each material were the following: Since I printed both the core and the diffuser together, I also used a prime pillar which was exclusively printed with T-Glase and an ooze shield printed only with PLA. The reason for this is that the ooze shield, as the name suggests, collects the oozing from both the PLA and the T-Glase (which oozes a lot), and the prime pillar allows to get the T-Glase filament running before printing each layer of the part. Do not worry that the surface is milky or cloudy. If you don't have access to an ultrasonic cleaner you can cure resin by exposing your 3D print to UV light (sunlight) for a short time.  As the name suggests, the current limiting resistor is used to limit the current going through the LEDs and avoid burning them. At this point it is important to make sure that the magnifying glass is already placed on the core, otherwise this will be a futile effort. Science. The motivation for this project came when I was building my new dual extruder 3D printer (which I used to 3D print the models I will later show) and somehow managed to short out the fan pins and burn an SMD … I also figured that connecting all of the LEDs in this approach would not be easy, as I would’ve had to squish the cables around the screws. Magnifying Glass 3D models for download, files in 3ds, max, c4d, maya, blend, obj, fbx with low poly, animated, rigged, game, and VR options. Similar Models . Fortunately for me, I’m not afraid of soldering so I decided to buy a bunch of transistors and go for the kill. Open the file in your 3D printing software and print out a copy. 3-D printing pen lets you create artwork, repair items, design jewelry, build models and more. 60º heated bed temperature with kapton tape. Old one broke, some quick OpenSCAD, a screw and as good as new. Magnifier is a tool that enlarges part—or all—of your screen so you can see words and images better. 3D printed magnifying glass fix for helping hands. It indicates, "Click to perform a search". Since I had the skills and the 3D printer, I volunteered both so that it wasn't a cardboard and tape production. If you’re like me and you haven’t yet mutated a third hand, you will probably find it useful to have some sort of alligator clips stand to facilitate soldering or tinkering. ... A magnifying glass. The model itself had a couple of requirements such that it should fit the 60mm magnifying glass, the 12, 5mm LEDs and the μUSB breakout board. My original idea was to divide the model in three different parts: the light diffuser, the core and the lid. I started with a very simple prototype which was probably unnecessary and a product of impatience. The goal of this project was to see if it was possible to create a 3D printed magnifying glass with no sanding or polishing needed. $11.33 $ 11. I 3D Printed a Magnifying Glass! Due to slight differences in the LEDs, one may take more current than the other, and can get destroyed (or at least will be non-uniform brightness). Benchy is a small 3D printed model designed for testing your 3D printer’s accuracy. Accidents happen, it's okay. One question, does that enamel protect from UV? Modelling the glass holder as I envisioned it was probably the most difficult part. Because of that, it can be printed … I've reduced the contact area as much as I can in my software, but still it is an issue. With Magnifier, you can turn your iPhone or iPad into a magnifying glass so you can zoom in on objects near you. The reason for the diffuser being completely solid is because that way I can take full advantage of the internal reflections produced on T-Glase, but if you’re going to use another type of material you might need to print the diffuser hollow. The final STL files can be downloaded here. Laboratory. I guess the next test is to leave a coated piece in direct sunlight for a few hours and see what happens. 5 years ago The first step in the process was to 3D print the models. This is a 3D printed magnifying glass printed using an SLA printer using clear resin. ( Log Out /  Perhaps others have mentioned this, but I didn’t see any comments.
