Stereolithography Goes Big

-

When it comes to hobby-level 3D printing, most of us use plastic filament deposited by a hot end. Nearly all the rest are using stereolithography — projecting light into a photosensitive resin. Filament printers have typical build volumes ranging from 1,000 to 10,000 cubic centimeters and even larger isn’t unusual. By contrast, SLA printers are often much smaller. A 1,200 CC SLA printer is typical and the cheaper printers are sometimes as little as 800 CCs. Perhaps that’s why [3D Printing Nerd] (otherwise known as [Joel]) was excited to get his hands on a Peopoly Phenom which has a build area of over 17,000 CCs. You can see the video review, below.

He claims that it is even bigger than a Formilab 3L, although by our math that has a build volume of around 20,000 CCs. On the other hand, the longest dimension on the Peopoly is 40 cm which is 6.5 cm longer than the 3L, so maybe that’s what he means. Either way, the printer is huge. That’s nearly 16 inches which is big even for a filament printer. Regardless of which one is bigger, the Peopoly is certainly much less expensive coming in at around $1,800 versus the 3L’s almost $10,000 price tag.

You can see on the video the machine is huge. It also wasn’t packed very well and took some cosmetic damage. It is also very loud thanks to a giant fan within. The prints did look good, though.

In particular, watching the huge djinn lamp grow out of the resin bath was pretty impressive. [Joel] found that some of his techniques used with smaller printers had to scale up when dealing with prints this large. With some finishing and painting, [Joel] wound up with an awesome lamp that wasn’t short on printed detail.

If you are wondering about the differences between printing with filament vs resin, we can help. If $1,800 is still too rich for you, you can get by with a few hundred, but with a 750 CC build volume.

Takeaways from the outcry over Dior’s Johnny Depp perfume ad: Tuesday Wake-Up Call

-
Welcome to Ad Age’s Wake-Up Call, our daily roundup of advertising, marketing, media and digital news. You can sign up to get an audio version of this briefing on your Alexa device. Dior pulls a perfume ad starring Johnny Depp Yet another luxury brand just had to backtrack after a culturally insensitive move. Dior on Friday pulled an ad for its “Sauvage” perfume, as Business of Fashion reports ; the spot starred Johnny Depp playing guitar in the desert while a Native American dancer, Canku One Star, performed in traditional dress. The company portrayed the spot as “an authentic journey deep into the Native American soul.” But the brand was quickly accused of cultural appropriation. Critics seemed most troubled by the juxtaposition of Native American imagery with the word "Sauvage"—which means “wild” in French, but which also evokes the history of labeling indigenous groups as “savages.”  LVMH-owned Parfums Christian Dior had apparently tried to proceed cautiously. It coo

When the coronavirus infodemic strikes

Social media sites are stepping up their efforts in the war against misinformation… specifically, the coronavirus/COVID-19 infodemic . There’s a seemingly endless stream of potentially dangerous misinformation flying around online related to the COVID-19 pandemic, and that could have fatal results. It’s boomtown in fake-news land riding high on the wave of people being left with their tech devices 24/7. I myself regularly see everything posted online from “hand gel is an immunizer” (nope) and “children can’t be affected” (not true) to “UK rules mean domestic abuse survivors have to stay with their abusive spouse” (absolutely not true at all and hugely dangerous to claim).  We even have engineers being spat on thanks to 5G conspiracy theories potentially resulting in transmission of coronavirus . Turns out a global pandemic is a lightning rod for pushing people to conspiracy theories galore, to the extent that some folks have to go hunting for guides to wean their family members a

Patch, Or Your Solid State Drives Roll Over And Die

Expiration dates for computer drives? That’s what a line of HP solid-state drives are facing as the variable for their uptime counter is running out. When it does, the drive “expires” and, well, no more data storage for you! There are a series of stages in the evolution of a software developer as they master their art, and one of those stages comes in understanding that while they may have a handle on the abstracted world presented by their development environment they perhaps haven’t considered the moments in which the real computer that lives behind it intrudes. Think of the first time you saw an SQL injection attack on a website, for example, or the moment you realised that a variable type is linked to the physical constraints of the number of memory locations it has reserved for it. So people who write software surround themselves with an armoury of things they watch out for as they code, and thus endeavour to produce software less likely to break. Firmly in that arena is the size
