Lasersaur build - SolidStateDepot From SolidStateDepot Lasersaur This page is here to document the rough pricing of they diy laser cutter called the lasersaur. More info is available at the nortd labs lasersaur page [1] Our goal is to bring the total price down as low as possible. Straight from the bill of materials the price is ~$4600. I believe we can get it down to around $2k without too much ebaying. Big fish These items look grossly overpriced on the BOM[2] water chiller - $400 Some people seem to run 40w tubes without cooling. Smaller savings There is probably some savings to be had by price checking locally whenever possible to avoid shipping and handling fees. Added costs There are some things we will need to look into purchasing that are not on the list. IR blocking goggles exhaust fan and tubing fire extinguisher possibly air assist compressor? To do Continue squeezing the price down.
Baricuda Extruder for 3D Printing Sugar and Chocolate by jmil UPDATE 2: HOW-TO ASSEMBLE Visual instructions posted on my flickr: UPDATE: My Z-idler files are now posted at the request of bill20r3. NOTE: Sugar and Chocolate precision extrusion should be controlled NOT by precision of air pressure (which is hard) but instead by precision of temperature (which is easy). Temperature controls viscosity which controls extrusion rate at a given temperature. The temperature to use depends on the material properties of your extrudate (read: the sugar). Chocolate is just as easy -- but don't use water! Get a Frostruder MK2 (you need the rubber stopper, tubing, and pneumatic solenoids) Lasercut these new parts out of 1/4" MDF or other RIGID wood. NOTE: There's no BOM because it will depend on the thickness of the material you laser cut. But the idea is you take the stopper clamp and top clamp and put the glass syringe in (I use Air-Tite.com). Enjoy!
Open Book on "Low-cost 3D Printing for Science, Education and Sustainable Development" Low-cost, three-dimensional (3D) desktop printing, although still in its infancy, is rapidly maturing, with seemingly unlimited potential. The hope is that this cutting-edge 3D technology will open new dimensions to science and education, and will make a marked impact in developing countries. This book gives a reasonable, first overview of current research on 3D printing. It aims to inspire curiosity and understanding in young scholars and new generations of scientists to motivate them to start building up their own 3D printing experiences and to explore the huge potential this technology provides –with the final goal of putting learning literally in their hands.

Hot Glue Gun Extruder for Your CNC Machine or 3D Printer 3D Printing still costs a few dollars and may be out of reach of hobbiest who do not have any budget. The goal of this instructable is to construct an FDM (Fused Deposition Modeling) printer extruder (a key component) using a $3 Hot Glue Gun. If you don't think you have seen an FDM machine, you probably have. There are many parts to a FDM printer and in this instructable I am going to concentrate on the extruder. Before I get any further I would like to extend a big "Thank You" to the open source community and all of the people who have contributed to the 3D printing community. So let's get started shall we. Just in case you want to see it in action before you do some reading, view the video below. Apple Logo (the one with the bite out of it) The apple turned out the best. Yay!
Tantillus Cable Chain and Brackets for PrintrBot by alexmadsen1 This thing provides the means to effectively manage cables on a stock Printerbot. It connects the x axis (X-CARRIAGE to the X-MOTOR mount) carrying the extruder and hot end cables. Continuing on it then connects the z axis (X-MOTOR mount to the PB-BASE) carrying extruder, hot end, x end stop, and x motor cables. I use cable chain links from thing # 1978 for the x axis. I created larger links (1056-01) for z axis. The bracket (1054-01) clips to stock PrintrBot PB-X-MOTOR-V2. Note: For my inplamentaion only the extruder motor cables had to lengthened/spliced. BOM for X and Z Axis Cable Chain Qty 1 1054-01 (BRACKET, CABLECHAIN, PB-X-MOTOR) Qty 1 1055-01 (BRACKET, CABLECHAIN, LARGE LINK, PB-BASE-V2) Qty 13 1056-01 (LINK, CABLE CHAIN - LARGE) Qty 12 thing # 1978 CableChain (chain links) Qty 1 1057-01 BRACKET, CABLECHAIN, X-CARRIAGE (to be uploaded at a later date) Qty 1 DIN 912 / ISO 4762, SOCKET HEAD CAP SCRE, M3 X 8, 12.9 ALLOY STEEL BLACK
openscad tutorial In this OpenSCAD tutorial series so far we’ve covered the basics of the OpenSCAD interface, how to make 2D forms, how to make some basic 3D forms, how to position those forms in 3D space, the different ways to combine forms, how to create mashups of one or more existing STL’s and OpenSCAD forms, and how to use modules to reuse your code to make your life easier. Although I described the last three tutorials as “intermediate” levels, that’s really only because you learned the basics so quickly from the first few tutorials. With just the basics you can literally design anything you can imagine. The “intermediate” lessons will let you do a little more and make your life a lot easier. Before we get started, the image is from BoriSpider‘s OpenSCAD tutorial homework. You may remember one of the first tutorials was about creating flat 2D forms using some simple commands.

Printrbot LC by abdrumm Printrbot is a 3D printer that had a highly successful kickstarter campaign... so successful, a laser cut design was needed to reduce production time. It has since become a hit. These are the unique parts that make up a Printrbot LC. Printrbot LC has a 6" x 6" x 6" (150 x 150 x 150 mm). This is about 3.5 liters. The Printrbot LC takes a couple hours to build - give or take. For more here:printrbot.com/shop/printrbot-lc/ PrintrBot : Les plans sont disponibles sur Thingiverse Il y a quelque temps, je vous ai présenté le projet PrintrBot, un imprimante 3D économique et simple à réaliser. Comme l’avait promis Brook Drum, son concepteur, il vient de mettre à disposition les plans de chaque pièce sur Thingiverse. Cela est une bonne occasion pour rendre cette imprimante totalement réplicative, mais c’est aussi un moyen pour réaliser la votre facilement si vous disposer déjà d’une autre imprimante 3D, ou si vous connaissez quelqu’un qui pourra réaliser les pièces pour vous. Vous pouvez donc retrouver toutes les fichiers 3D de chaque pièce au format STL sur Thingiverse. Et pour continuer dans la simplicité, Brooke Drum a également réaliser une série de photos permettant de suivre toutes les étapes de l’assemblage de l’imprimante 3D PrintrBot. Vous pouvez retrouver la galerie de photo sur flickr.com.
