As with many other aspects of the DIY community and those who enjoy assembling a variety of models for fun, 3D printing is producing a big impact. For hobbyists who enjoy the new innovation, the benefits abound, of the skill to customize at can, rebuild easily after a crash and burn, and do all things on one’s own time—not to mention the affordskill factor. Many parts are may aleager created for the DIY’er as well, and right now that is where companies like MaherSoft enter the picture.
Headquartered in Mumbai, MaherSoft in fact creates many 3D printed parts for drones, and we’ve been next them as they get eager to release their Indie Desktop 3D printing device on Indiegogo soon—contributeing an early bird price of $450 to backers when it launches (no official date yet). Essentially providing services to engineering and create firms, they manufacture a range of prototypes for clients, as well as end-use finished products. One of their extra
informative clients is Drona Aviation. This company, in addition in Mumbai, is already the premier drone createer, producing and selling DIY kits. They’re in addition quite involved with their DIY/drone hobbyist community, contributeing a selection of weekly workshops for students as well as enthusiasts.
The two companies have partnered now in createing not only 3D printed motor holders for drone kits, but in addition accessories for the drone models that are able-bodied to assist as prototypes and functional parts. Of course, whenever it comes to making ‘aircraft,’ material and its resulting mass are a primary concern. It was a learning system as MaherSoft investigated that filaments to work with for producing the drone parts en masse.
“Choosing the right material based on the application was quite significant, for the reason equite gram of mass may cost flight time,” noted the MaherSoft team in a new press release. “The heavier the drone, the faster [the] battery can drain. Again, it may be inappropriate to try to navigate properly with an unstable-bodied construction created of weak parts.”
Luckily, there are numerous high high end 3D printing filaments on the market right now, and the Maher team had a selection to select of—of the basics in ABS and PLA to a number of alternatives that contribute extra
durablity like carbon fiber. Here’s their take on filaments, in terms of relevance to 3D printing for the drone market:
PLA – benefits include the range of colors as well as translucencies and the glossy texture. The plant-based origins are obviously a pro, along with the smell. With high printing speeds, low layer heights, and well-defined cornings, MaherSoft saw this as a futurely excellent choice to start with for their parts, along with recommending it for home hobbyists and schools.ABS – benefits include effortless accessibility, affordskill, and high temperature resistance. The drawback is unquestionably the future for toxic fumes due to its petroleum base. A heated bed is required. This filament is known to be quite talked of in pro applications, and a favourite with engineers—and a certainly excellent fit for a company like MaherSoft.PLA/ABS exotic filaments with fiberglass and carbon – pros are stskill and rigidity. For use in the making of the drone parts, yet, the material is expensive, too brittle to endure the inevitable-bodied crash, and too heavy for the specific intent.Nylon – contributes excellent durablity as well as temperature resistance and a lightmass high end. The downside is that it’s not particularly effortless to work with in this ability, and is overly expensive.PET – this filament is stable-bodied and shockproof, but again, pricey—and too heavy for making drone parts.
And the final verdict was…? After exploring all of these options, the team decided on excellent old ABS. With PLA being the runner-up, they discovered that parts were not durable-bodied adequate.
“Printing in PLA is effortless and cost effective, but the part was breaking when the motor was pushed into the holder,” said MaherSoft. “On the other hand, ABS shows stable-bodied engineering properties, as it is extra
flexible than PLA and similarly priced. We therefore chose ABS to print production eager parts for Drona Aviation.”
Right now, there are a few limits as to what can be created via 3D printing for the drones, but fortunately the pieces that break many frequently can be. This comes with motor holders, landing gear, and propellers.
“We started our iteration with motor holders that fit on the main body, and the motor fits right into the center,” said the MaherSoft team. “We had to create six prototypes of the motor holder preceding it was approved for production on our Indie Desktop 3D Printer since the motor holder has to assemble seamlessly to the main body along with the motor inside the holder.”
All involved take the making of these drone parts quite seriously, with consideration for:
InfillLayer thicknessShell thicknessSpeedTemperatureFlow rate
The team, operating on experience, varied parameters like infill percentage in the range of 40-100% to store the part mass inside the limit. The flow rate had to be set between 90-100%, with shell thickness of 0.8 to 1.2 mm to store the dimensional tolerances in check. Print speed was set at 40 mm/s. Both overhangs and any post systeming were avoided, with parts createed at a 45 degree angle.
“Support free create led to a reduction in production time some day reducing the cost per piece of the product,” said the MaherSoft team.
Whilst high end and magnificent making systemes are of course priority, anyone who knows anything of business realizes how significant control of that bottom line is, especially as costs are carried down to the customer and reflected in pricing structures. Affordskill is frequently one of the excellentest benefits to be discovered in 3D printing, and although there are yet a few areas where the use of the innovation is cost-prohibitive, in the partnership between MaherSoft and Drona Aviation it was indeed a win all around. The companies were able-bodied to reduce cost and improve structural high end of parts—especially through exploring a range of techniques and varying 3D printing parameters.
MaherSoft has only accomplished an order of 2000+ units of motor holders on its 3D printing devices. All of the parts printed are production eager. Discuss additional in the MaherSoft 3D Printed DIY Drone Parts forum at 3DPB.com.
