Our translucent polycarbonate films for light diffusion are particularly impressive due to their mechanical strength and impact resistance. In addition, they have a distinct temperature resistance from - 40 °C to 130 °C (continuous operating temperature of 105 °C), a high dimensional stability as well as good dielectric and insulating properties.

The market for light-emitting diodes in lighting is booming. This is hardly surprising since the LED technology has huge advantages: they consume less energy than incandescent bulbs and discharge lamps and help protecting the environment, and have a much longer service life. If you are designing or manufacturing an LED lighting component for commercial, industrial or residential use, we have the solution you need. We offer a wide range of technical films for the diffusion of light and LED light. These films act as diffusor to avoid that the light source gets visible. In addition to a high light transmission, all our diffusor films show a good heat resistance.

First place the M3 nut at the extremity of the bolt and place it in the hexagonal hole of the "X stage table". Fit should be tight. You can heat the nut a few seconds with a lighter to help the insertion. If the nut does not hold in place by itself you should glue it.

Check that the translation is smooth and the springs force the table down after unscrewing the knob. If so congratulation, your linear stage is finished. You may add the top hot melt inserts according to your needs.

You may add the top hot melt inserts on the top surface depending on your needs. If you plan to use this stage in an assembly and you know which mounting hole you will use it is not necessary to add inserts to all the positions.

For the Z stage you will need the 3D printed parts: 1x "Z stage base", 1x "Z stage table", 1x "Z stage middle" and 1x "knob".

The 3D files for all three stages are freely available on the following websites. Take the time to read the description as various versions are available depending on the tolerances of your 3D printer and the type of hot melt insert you want to use.

Translucent diffusor materials are designed for light diffusion in high quality lighting applications. These films in milky white color contain a scattering additive specially developed for this application for uniform light diffusion. When used in backlit components using LED light, our light diffusion films provide uniform and homogeneous illumination over a wide area.

Linear stages are mechanical platforms capable of precise translations in one direction. They are often used in science, like in optics to place components on a bench, in microfabrication to interact with microscopic devices or to place a sample under a microscope. But generally speaking they are very handy in a workshop, whether you want to make a complex soldering jig, do some macro photography or mount a camera.

If you have any further questions about our range of plastic materials, suppliers such as Lexan and Makrofol, the color and light transmission of our films, our cutting service into sheets, delivery and any other concerns, we will be happy to advise you.

FDM printers can hardly provide the resolution required to produce a perfectly smooth sliding mechanism without any play. For this reason i aimed for all the 2mm rod holes to be slightly tight and you will likely need to adjust it. The best method i could find to obtain a perfect fit consists in using the same 2mm rods (not drill bits), and an electric drill to locally heat the PLA and deform it to the right diameter.

The different light diffusion films differ from each other in terms of light transmission (light transmittance), the half-power angle and color. Depending on the application, the light source, we recommend you a material with suitable light values. The surface of the film has a slight glare without being reflective.

The translucent diffusor films impress with their homogeneous diffusion of light and provide an excellent light diffusion. This makes them the ideal solution for a wide range of applications in lighting technology and the lighting industry. The diffusor films are used for spreading light and dividing the brightness and glare over the whole area of the lighting surface. The diffusion can vary from translucent and strongly light-scattering films. We supply you our film diffusor as rolls or sheets. Just tell us the sheet size and we prepare you a competitive quote.

A diffusor film is needed to spread and diffuse the light of the LED over the entire surface of the light surface. Like this no single light sources are visible, but the optical brightness is spread over the whole surface to achieve a perfect illumination.

Thanks to their surface structure with a slight glare (without being reflective), our polycarbonate light diffuser films are characterised by good and constant printability. Furthermore, our diffuser films can be cut, punched, lasered (partly possible), embossed and glued using professional accessories. Polycarbonate light diffuser films are suitable for deep drawing and back injection and the insert moulding process (FIM) as well as high pressure forming (HPF). The films we offer can be cold and hot formed. Our polycarbonate light diffusion films are also suitable for special applications such as deep drawing or high-pressure forming.

After that place the "X stage base" and "X stage table" together and insert the rods in the holes. At this point the holes should be slightly undersized and the parts should have difficulties sliding. You can use a rod and a drill to adjust the hole size until the two parts can slide smoothly together. Please refer to the optional step 8 "Adjust The Hole Diameter" for more details.

All stages are designed to be stackable and have the basic dimensions of a 65mm square. The X stage is 18mm thick and has a total course (maximum displacement) of 20mm in one direction. The XY axis is 30mm thick and also has a total course of 20mm in two directions. The Z stage has an adjustable thickness between 26 and 36mm. For the X and XY stages, the stages moves by 0.7mm per turn of the knob. For the Z stage the thickness varies by 0.24mm per turn.

All stages can be assembled and/or fixed to a substrate using 6mm M3 screws. The mounting holes are arranged in an array with a 20mm base spacing (see illustration). I plan to upload different versions compatible with standard optical tables but you can contact me if you need a specific spacing. For the X and XY stages, fixation can be done by driving the stages to their endpoints if you want to use the outer fixation holes, but in general it requires to disassemble the stage.

To do that first install all the rods that form your sliding mechanism and test the fit. If you see that one hole is too tight remove only that rod (keep the other ones in position to ensure the two printed parts are hold correctly one related to the other). Mount a long rod on your drill, insert it in the hole and spin it for 15 to 30 seconds. The rod will heat up because of the friction and the PLA will deform. Move the two sliding parts back and forth during the whole process to make sure the "forming" is uniform over the whole mechanism.

Those 3 designs are: 1) a single axis translation system "X stage", 2) a two axis translation system "XY stage" and 3) a single axis translation system with the translation perpendicular to the stage: "Z stage". My design requirements where to make the systems as compact as possible, very stiff, without backlash and using only cheap, standard elements. The results cost bellow 5 USD, can be built in 10 to 20 minutes and can give you a positioning accuracy close to 10 microns.

I tried to design this project with standard, easy to procure materials but that doesn't guarantee you will have them on stock. Here are some links to help you gather what you need. For each one, I've tried to include one link from Taobao (Chinese platform) and one from Amazon.

As a specialist for technical films and thin sheets, the König Film Centre offers you numerous diffusor / light diffusing films for lighting applications and the design of high quality lights. These are polycarbonate films (plastic) of the brands:

Place the "Z stage table" on top and fix it by placing the 20mm springs in the top holes of the table and holing it in place with the 2x 25mm flat head screws.

After that place the "XY stage base" and "XY stage middle" together and insert the rods in the holes. Use a rod and a drill to adjust the hole size until the two parts can slide smoothly together (refer to the optional step 8 "Adjust The Hole Diameter" for details). Disassemble the parts and repeat the process with the "XY stage table" and "XY stage middle". You should use a marker to note which side of the "XY stage middle" inserts in the base and which part corresponds to the table as it may not be completely symmetrical anymore after the hole adjustment.

If you like those, i have also designed two rotation axis shown in the introduction video: Link to the In-plane rotation axis RZ stage, and to the Out-of plane rotation (goniometer) RY stage.

We provide you polycarbonate light diffusion films in thicknesses from 150 µm to 500 µm as sheets or rolls. The roll length of each diffusor film varies depending on the thickness. We are happy to cut and convert the rolls into rectangular sheets in the sheet format you require. Just tell us the required sheet size and we will send you an offer with an attractive price for sheets or rolls.

You may add the top hot melt inserts on the top surface depending on your needs. If you plan to use this stage in an assembly and you know which mounting hole you will use it is not necessary to add inserts to all the positions.

I recently dedicated quite a few hours of my life designing a 3D printed micromanipulator (see here if you are curious) and concluded that it is possible to make very good 3D printed sliding mechanisms using inexpensive 2mm metal rods as slides. Based on this design principle i made 3 types of linear stages and this instructable is meant to illustrate the fabrication process.

The first step to build these stages is to cut the rods to the right dimensions (X stage 4x 64.5mm, XY stage 8x 64.5mm, and Z stage 4x 25.5, 2x 44.5 and 2x 61.5mm). You may off course do that by hand if you wish but i designed some cutting guides to help you with the task. Just fix the guide in a vice, insert the rod to the end and cut at the extremity. To facilitate the insertion, i recommend making a chamfer at one of the rod's extremities by holding it in a drill and spinning the tip against a file.

Place the M3 nuts at the extremity of the bolt push it in the hexagonal holes of the "XY stage middle". There are two nuts to insert. Fit should be tight. You can heat the nut a few seconds with a lighter to help the insertion. If the nut does not hold in place by itself you should glue it.
