The Lumen – The LCD based SLA 3D Printer.

With FDM 3D Printers being produced at very corner, most of these machines simply do not have the ability and finesse to do small parts at high resolutions, even the machines that CAN pull this off, have print times that are just way too high to be practical. There has always been a need for a machine to print really small parts at seriously high resolution and so this is the part where we introduce, The Lumen!

The Lumen is an LCD Based SLA 3D Printer. By using UV reactive liquid resin, it cures the polymer layer-by-layer until it builds up the 3D print from the bottom up with incredible accuracy.

Now the 3D Printing world is no stranger to this type of technology, Formlabs has been doing this for many years now with the use of lasers which gets pretty pricey but also complicated. DLP 3D printers are doing some awesome and similar work using DLP based Projectors but these machines can get really big since you have to fit an entire projector into the bottom of the machine. The Lumen? It has its own tricks up its sleeve.

The Lumen uses a UV Light source and a high resolution LCD display to control the images that are shown which is proving to be incredibly accurate and MUCH more efficient.


With almost 95% of the frame, chassis and build platform being built of out solid, machined aluminum. This little guy is as solid as a rock! There is simply no room for play at all.  He boasts a build volume of 120L x 60W x 150H (mm) and a 2k (2560 x 1440) resolution LCD Screen (536 PPI). The Z Axis allows The Lumen to get all the way to 30microns in layer height. As you would imagine this gives way to some phenomenal print qualities!


H
ere is all the specifications it:

Build Volume: 120L x 60W x 150H (mm)
Resolution: 30 microns. 2k (2560 x 1440) 5.5″ LCD Screen.
Light Source: 30W UV LED (405nm)
Power supply:  220 AC. 12V Power Supply built into the printer.
Resin Vat: 0.175mm FEP Film
Communication: USB, Ethernet or WiFi.
Net weight: 8KGs
Physical dimensions: 256L x 214W x 415H (mm)

The Lumen ships with all its cables and accessories and a small toolkit to get you going on your resin printing journey!

The Lumen is capable of using any conventional 3D Printing Resins that can be found on the market today. Netram will have their own 3D Resins available soon! The pricing is ranged between R800 to R1200 a litre depending on the type of resin you’re interested in. Some cure hard, some cure soft and others are made for casting molds.

The Lumen remains relatively open source and runs Photonic3D. By saying that we mean the software that it runs is open source based but if you know what you’re doing with software, you can upgrade your own machine when new versions become available!

The Lumen will be retailing for R18,500 but 10 pre-orders are available for an early bird pricing of a mere R15,600. The pre-orders require a 3 week production lead time but you’re first in line!To find out more please check out The Lumen product page!

Boeing looks to build 3D-printed modular satellites

Boeing Co. is taking steps to build satellites more quickly through new production practices that will rely more on 3D printing and involve fewer workers, which eventually could transform the aerospace giant’s traditional way of turning out high-end commercial and military spacecraft, The Wall Street Journal reports.

The company’s proposed changes, spelled out in an interview by Paul Rusnock, who leads Boeing’s satellite business, have already taken hold in the small-satellite world and shaken up that segment of the industry.

“Our roadmaps are really focused on simplifying the overall architecture and design of satellites so they can be assembled more quickly,” Rusnock said. “Making them simpler, easier to put together” also reduces production glitches, he said. The effort is part of management’s latest bid to become more competitive in an evolving industry. “We cannot continue to do what we’ve been doing and stay competitive,” he said.

Historically, satellites generally have relied on highly customized, by-hand assembly procedures that slowed production and boosted costs. But starting with small satellites, proponents of change are devising new methods that entail bringing together standardized, pretested modular components and sidestepping most of the painstaking testing and integration currently carried out on the factory floor.

Now, internal test protocols “basically tell the spacecraft to check itself,” Rusnock said.

The outcome, according to Boeing officials, ultimately is likely to reduce the longevity of some communications satellites – potentially cutting in half today’s typical useful life of 15 years or more – partly by eliminating certain expensive redundant systems on board.

The benefits of the new process, according to Rusnock, are slated to be lower acquisition costs for operators while provide them greater opportunities to launch upgraded technology before hardware becomes outdated in orbit.

Boeing’s satellite models typically take five years to design and build. Some of them can be as large as a school bus, weigh thousands of pounds and cost roughly $150 million. The number of satellites built annually can be counted on two hands.

Ultimately, Rusnock said, “there’s nothing stopping us” from realizing huge reductions in production schedules. Final assembly and painting of an entire Boeing 737 jetliner takes 11 days, he noted, “and we’re looking in that direction as to how we make that happen” for spacecraft.

Bobwi mini robot

Today it was announced that Netram will be bringing our version of “Bobwi” mini robot to market within the next 3-4 weeks. it will be available for purchase online at an affordable price,  for shipping throughout South Africa, so watch this space. Ours will be smaller compact version which will be ideal for younger kids to experiment with. This will give young minds an opportunity to develop and explore while having fun. They will be able to control the robot using their own smartphones. How cool is that?

Have a look at these videos to see some of the features you can look forward to.

Another version showing some dancing moves.  the possibilities are endless.

 

You want five reasons to teach your child robotics?

  1. Its fun
  1. A great way to introduce programming to young minds

Programming can be too daunting. By having control of a physical robot and seeing what goes wrong, young minds can learn what robots can and can’t do. They also learn the need for precise instructions. Robotics stimulates demand for teaching science, technology, engineering and maths in schools. Young minds learn about science, engineering and maths and get to understand the interrelationship of how these subjects link together.

  1. Provides them with useful job skills for future employment

There will be a need for people to be program mechanical devices in the near distant future. The drone industry has taken off. By programming robots at an early age, kids can discover if they have aptitude and interest in technology and robotic science and create a career path for themselves.

  1. Suitable for all children

Robotics are particularly suitable for engaging with children diagnosed with autism.  Robotics are great for  games and teaching skills to autistic children.  Repetition, predictability and clear emotions work well in developing these children.

  1. Demystifies Robotics

Understanding what machines can and can’t do is the best way to address fears of the unknown. By trying to build and program robots will gives children appreciation of their own capabilities and strengths. and its FUN!!

Prints here! Get your Prints!

With 3D Printers on the market priced between R10,000 to R25,000, we understand they are not the cheapest machines in the world but they are probably one of the most handiest. We’ve had a few situations where guys have needed a print done but simply can’t afford their own 3D printer, we have found a solution for  this.

Print Picture 2

Netram will now be rendering 3D Printing as a service. If you’re looking to get something printed and you have the model file available, all you need to do is send the artwork to us and we will get back to you with a quote, No problem.

We will soon be offering an artwork service for people who need a model to be made up, so if you’re looking to print a part that goes on the contraption for your What-cha-majig that no one has heard of, we’ll soon be able to help you out, but we will keep you updated when that service is available.

For now, your print sizes are limited to 200x200x200mm, which is pretty huge if you ask me. To give a ballpark figure, the calculation on price per print will depend entirely on the weight and time, The bigger the object or the more solid you need the object to be, will effect the price and vice versa. The file formats we accept are .OBJ .STL .DXF.  To get a quote, just send us an email with your artwork to production@netram.co.za
