richrap blog Like many who print with natural PLA hollow objects start to look like good fun, they can be a little tricky to print but here are a few things I have printed so far and a few tips that worked for me - I printed a few things with the 'Fill' module turned off in Skeinforge, this is ok, but you only get one (fragile) shell 'outline' and no base or lid on your model, for me this seems to be a problem with 0.25mm layers, the material seems to collapse on itself. So I experimented slowing down the print but really I wanted to have extra material both to make the hollow object stronger and help it stay up during a normal speed print. If you leave the 'fill' module enabled but set the infill density to 0 you get a hollow model and you can select multiple outlines and also get a nice base on your model, this seems to work really well if you are trying to print large things without a heated bed. Solid base on the legs gives it a really good grip on the bed. Rich.
in italiano - RepRap in Italian/Costruire una reprap Questa pagina non è stata verificata e potrebbe contenere informazioni non corrette Ci sono diversi modi per costruire una RepRap o una Repstrap; il metodo scelto per queste istruzioni è stato scelto per minimizzare le conoscenze e gli strumenti necessari. Per esplorare altre opzioni cliccare su: Build a RepRap-Advanced ("Costruire una RepRap - Avanzato"). Il Design Classico RepRap è "Darwin" nell'immagine a destra. La RepRap è stata attentamente studiata per utilizzare solo componenti che possono essere costruiti con una RepRap ed altri componenti economici. I Cloni RepStrap Darwin sono copie abbastanza accurate del tipo Darwin ma i componenti RepRap sono sostituiti da componenti creati in un modo diverso, magari in plastica stampata, in acrilico o compensato tagliato al laser. Altre RepStrap, queste sono altre stampanti 3D in grado di fabbricare componenti di RepRap (Darwin) ma che non sono strutturalmente simili alla Darwin.

Low cost 3D printing filament extruder for recycled plastics Low cost filament extruder made from 10 mm ID stainless steel tube, silver soldered inside an ordinary plumber 15 mm copper tube (melt zone) Auger is a 10 mm wood drill bit with the end cut off 5-10 mm in the melt zone. 1 mm hole in a brass endstop at the end of the copper pipe. Aluminium block with a 15 mm hole to fit around the copper pipe. Fixed to the outside of the aluminium two 220 volt 200 degree PTC heaters( I tried 12 volt 230 degrees but the temperature was to high) Insulated with glass fibre cloth. The ptc heaters are available on aliexpress for $1 each) System driven with a car windscreen motor at the low speed (I have a 2 speed motor - salvaged from scrap yard) I use the white plastic that is in the inside of the doors of scrap refrigerators. Cut it up with a circular saw and extrude that to a filament of 1.75 mm I use this filament in my Delta printer on a daily basis.
Bukobot 3D Printer - Affordable 3D with No Compromises! by Diego Porqueras Affordable Desktop 3D Object Printing for EveryoneGreat First Printer..or Second..or Third! Easy to BuildEasy to Expand or UpgradeHigh Quality ComponentsFaster than most printersDual Extruder OptionGreat DocumentationOpen Source Environmentally Friendly Options You can create almost anything you can dream up with a Bukobot 3D printer, right on your desk! The Buko framework is the next generation of Open Source 3D Printers. 3D printers using this new framework are called Bukobots. With many months in development, I have combined the best ideas from the open source community and some new ideas of my own into an extremely flexible open source 3D printer design. 3D printing is the process of creating solid objects from digital files. Here's a timelapse video of a Bukobot making the CrashSpace Pyramid logo by theron ( Note: I have no association with thingiverse.com, I just love the site! All kits will include a 1lb of plastic filament to get you started!
Filament Tolerances and Print Quality This entry was posted on November 29, 2011 by Luke Chilson. Filament Tolerances is a subject that doesn't get much discussion, yet is arguably the most important quality to look for when choosing a plastic supplier. Hobby Printers use what is traditionally known as Plastic Welding Rod. When examining the quality of filament there are two things to look for; the Precision of the Diameter to which the plastic is extruded and the roundness of the filament. Filament is visibly poor. Proper filament is round and very consistent. The filament on the left is 3mm Natural ABS Filament we obtained as a sample while searching for suppliers. On the right is how 3d printer filament is supposed to be. Tracking Diameter Error For a printed object to look nice, be structurally strong, and have the appropriate dimensions your printer needs to know exactly how much plastic it is pulling through the machine at any given time. is the capital greek letter Delta and in this case indicates error.

ErikZalm/Marlin Options This page attempts to make some sense, in general, of how all the pieces fit together to create a RepRap. However, if you want to skip all this stuff and get straight to getting your hands dirty then your best bet is to take a look at The incomplete reprap beginner's guide and the build instructions category. In addition to those guides, you may also want to take a look at the links under the Models section below. RepRap Component Structure. That being said, to get a higher-level overview, we must start with discussing the different models of repraps, then go on to the four main components of a reprap: The software toolchain. Models These days there are a growing number of many great and detailed build instructions for repraps! Software Toolchain The software toolchain can be roughly broken down into 3 parts: CAD tools. CAD Tools Computer Aided Design, or CAD, tools are used to design 3D parts for printing. Software Files There are very few interchangeable CAD file formats. CAM Tools Part Files

Comparing Entry Level 3D Printers This entry was posted on February 21, 2012 by Luke Chilson. Dec 5, 2012 : Please note that this post contains out of date information and is in need of revision. May we suggest these other fine links? The Differences Between ABS and PLA 3D Printer Filament Buyers Guide These days there are a number of personal 3D Printers to choose from. Below are some statistics and descriptions of currently available or soon to be released personal 3D printers. Absent are the more varied and technically involved printers of the RepRap branch (though every bit as capable and very much worth checking out). I think it is worth clarifying why a couple printers did or did not get included (at least yet) in this post. Time has gone into distilling the comparable features that will most decide the limits of what you can do with the machine.
