Reprap development and further adventures in DIY 3D printing

Reprap development and further adventures in DIY 3D printing
One spool to rule them all... Coils and coils of lovely 3D printing filament, I'm usually surrounded by them, I struggle with them and often spend time and energy mounting, clamping, switching and feeding them into to various printers. There has to be a better way. (lets please all find a better way) * The problem * Every single one is different, bare coils or reels, some are even different from the same manufacturer.

A Simple, Low-Cost Conductive Composite Material for 3D Printing of Electronic Sensors 3D printing technology can produce complex objects directly from computer aided digital designs. The technology has traditionally been used by large companies to produce fit and form concept prototypes (‘rapid prototyping’) before production. In recent years however there has been a move to adopt the technology as full-scale manufacturing solution. 3D Printer, 4th Generation Shipping Time: SHIPPING WITHIN 2 WEEKS! Now with an all-new extruder! The Solidoodle 4 is our latest generation printer. With a new extruder, concealed components, and thumbwheel calibrations, it’s our easiest printer yet!

Enable Auto Leveling for your 3D Printer with an inductive sensor (Marlin Firmware) The auto-leveling sensor will be replacing your 3D printers z-end stop on your control board. You won't need the old z-stop because your sensor will be probing the bed for it's z-position. Make sure your sensor has a detecting distance of at least 4mm. In reality, this might be lower depending on the sensing material. Your sensor should be mounted close to the nozzle and able to reach near the corners of your print bed when mounted. Solidoodle 4 keeps 3D printing under $1,000 (video) Sam Cervantes didn't stand on his new printer when he brought it by our offices the other day. He thought about it for second, a nice reprise of the day he introduced us to its predecessor late last year, but, well, he'd only just pulled that first unit out of the box for the first time, and he didn't want to scuff up its finish or dent the new enclosure. As to whether the new 3D printer could sustain the weight of a full grown man, he certainly thinks so. It's still got that steel structure, after all. Maybe we can convince him to put on a show at CES in January. Structural integrity questions aside, the latest printer from Solidoodle is a nice looking thing, certainly.

3D Printer Frame Design There are a few very good reasons why building 3D printer frames using laser cutting and CNC cutting is so popular. First, this type of construction is very inexpensive. The material most commonly used for computer-cut 3D printer frames is MDF or plywood, both of which are very cheap. Second, designing laser cut panels is extremely easy and does not require specialized software as the design work is basically done in two dimensions. Third, building frames from computer-cut panels offers easy construction while also offering a fairly good-looking (but still mostly appealing to hobbyists) finished product. Technology - 3D printing: A new dimension to faking it Thanks to 3D printers, budding counterfeiters could soon create parts or goods themselves. The problem for authorities is that copying physical objects is not always illegal. Rolex watches, Burberry hats and other fake luxury goods are increasingly becoming small beer to ambitious counterfeiters. They are now thinking on a far grander scale – both in terms of size and the tools for the job. According to Der Spiegel, a “fake” copy of a Beijing office and retail development designed by London-based architect Zaha Hadid is already being built 900 miles (1,500km) away in Chongqing.

Extruders 101: A crash course on an essential component of your 3D printer Direct Extruder Weaknesses Because direct extruders are directly attached to the hot end, its mass must be moved along with the hot end. Moving more mass around means more likelihood for backlash, overshoot, and frame wobble (there are other things, but these are the most important for the purposes of this article). GoldFish Alpha – Download – GoldFish is a CFD Solver for grasshopper written in C++ and C# I did this because C++ is fast enough to allow the user to interact with the problem and see updates in real time. It has been a long time since i wrote this but i have finally gotten around to getting it out there. Its initial release has limited functionality but there will be more to come.

NavSpark: Arduino Compatible with GPS GNSS Receiver English, Simplified Chinese (简体中文), Traditional Chinese (繁體中文) For viewers in some region having problem seeing the above YouTube video, the contents is here: Powerpoint (简体中文), Youku Video (简体中文). NavSpark 点名时间上中文說明: NavSpark is a small, powerful, breadboard-friendly, 32bit development board that is Arduino compatible, with a world class GPS receiver as on-board peripheral, and under $15. There is also NavSpark-BD, a variant model having world-class GPS/Beidou receiver as on-board peripheral, that enables you to adopt new GPS/Beidou satellite navigation technology when Broadcom Qualcomm just recently came out with solution supporting Beidou to their tier-1 smartphone customers like Apple and Samsung.

The 3-D printing revolution has begun There’s a rite of passage for many entrepreneurs with a great product idea: Ship your design to China to get a prototype made on the cheap, and cross your fingers. Thanks to the increased accessibility of 3-D printing technology, Made In China is no longer the only option. In fact, 3-D printers are empowering entrepreneurs to design more innovative products at home, taking some mystery out of the process, and saving them time and money so they can better compete with larger companies.

Jumbo 3D-Printer PRotos X400 The biggest 3D-Printer based on RepRap technology known to us with a printing area of 400x400x350mm. The new PRotos X400 by German RepRap combines the advantages of the OpenSource technology with a performance and a quality “Made in Germany” interesting for professional operators in machinery and plant engineering, small batch production or in electronic industry and for ambitious private users. A layer thickness up to 0.1mm and a printing space of 400 x 400 x 350mm, allow the printing of precise models with a volume up to about 56 liter.
