Hi Jerry! We're sincerely sorry for the issues you've experienced with our prototype product. It's a relief to hear that you and your team remain unharmed, and we greatly value the feedback you've provided. Rest assured, we're diligently addressing these concerns to ensure our printers are both excellent in quality and safe for use. To reassure our valued Kickstarter backers, who are our earliest and most important supporters, we are committed to ensuring the highest quality in our products. If any quality issues arise with our printer, we sincerely promise to provide a full refund or a replacement within 60 days from the delivery date (calculated from the receipt date), completely at our cost. Your trust and satisfaction are our top priorities. Here's what we're doing to enhance our printer: 1) Power Switch Upgrade: We take full responsibility for the malfunction of the power switch, which was a result of inadequate power support for the required load. This led to overheating and an automatic shutdown, causing the metal casing to show signs of damage (like the "explosion" you mentioned). This is a common safety feature in many electrical devices, designed to cut off power when overloaded to prevent further problems. We've addressed this by replacing the original plastic switch with a more robust, high-capacity metal switch. 2) Improved Temperature Control: We're modifying the temperature control on the front touch panel for easier access and operation. 3) Resin Bottle Design: The resin bottle isn't completely sealed because it needs air to work right. Understanding concerns about spillage, we've developed a secure holder for the resin bottle, ensuring it stays safely in place during operation. 4) Integrated Washing Station: Currently, our printer offers dual functionality with both printing and post-curing capabilities. Looking ahead, we plan to integrate this washing station feature directly into our printer, enhancing its overall functionality and user convenience. Additionally, we've provided a washing station as an optional add-on on Kickstarter. 5) Timed Curing: We're currently testing a timed curing feature and anticipate its introduction shortly. 6)Enhanced Touch Screen: We are optimizing it to improve sensitivity. 7) WiFi Connectivity Improvement: Regarding the WiFi file transfer issues, several factors could be responsible, such as unreliable router connections, slow internet speeds, network dropouts, or incomplete transfers from slicing software. To address this, we are developing a solution that bypasses these router-related problems. Our team is testing a new device that allows for direct file transfers from your computer to the printer, removing the need for a router and ensuring a more stable and reliable connection without the worry of network interruptions. We really hope this shows you how serious we are about making a great printer. We appreciate your support and patience as we work on these improvements. Thanks for helping us get better! Best, UltraPrint Team
I know you were not able to showcase the heating aspect of the machine, but I'm curious if you recall anything about the way it was design while you had it open? Their video showcasing thermal readings show that vat & base at about the same tempt as the air coming from the holes. So I'm curious if the heater do indeed heat from below (and of course from the holes), or if it was a smoke and mirrors situation where they let everything heat up and then opened the lid to take temp readings.
I specifically remember 2 wires coming out of the electronics for heating. Those wires split and went to the two definitively separate heaters in the vents shown in the review video. I do not remember if there was a 3rd wire that went below the vat to heat from the bottom. While I did have these issues, Ultraprint did nothing to me to make me not trust them, and as it was shown in my review video (via text at the bottom), and as you might have seen in Ross's video/Kickstarter page, it does appear it heats from the bottom. I never traced those wires to the base of the vat, so sadly I cannot provide info on this and I dont have the time to open the printer up again. I really wish I could do that because now I am curious myself. What I can tell you is this though, if it can heat from the bottom there is are 3 separate heaters. Two top mounted vents and the bottom heater. There is no way to individually turn them on and off. It's either all on or all off.
@@ThePrintHouse oh I saw you videos this morning, I just hadn't fully woken up at the time I was seeing them lol. I'll admit, I was watching/listening while I drifting in and out while waking up XD But yes, I was also in his chat watching his stream :D
@@kaelichambers9261 that's honestly the best way to wake up though. It'll get your brain processing a tiny amount of info so it prevents you from falls back asleep!!
Hi Jerry.... Thanks for the video. I'm very much on the fence about purchasing this printer. So, your answer to this question might help me decide. I am sorry to hear your initial bad experience with this printer. However, this makes you uniquely qualified to possibly answer my question if you so choose. Don't know if your aware of Ross's @ F.H. Theory on what this printer looks similar too. I won't go into that. But if correct, it would be a blessing to me since that is the printer, I've been considering purchasing for its superior light source. Since you were able to have your hands & eyes inside this (pre-production Unit) & I know... This is subject to change. So, with the printer sent to you, At the time of your opening it, repairing it, & shooting this video. Did you happen to notice if the light source is a single lens? Or rather a matrix grid of lenses like most resin printers have. If it is a single lens possibly similar to the one Ross likened it to. This will be the printer I choose because of it's flip top & heater as well. Much Thanks.
Sounds like they have the switch carrying the full current of the power supply, usually you would run that power and switch through a mosfet to reduce the impact on the switch so that you don't weld or blow out the contacts. Not great design by ultraprint but somewhat understandable mistake in a prototype unit. If they are blaming the switch, thats a HUGE red flag though, its clear the switch failed because of their power supply design, not because of the switch itself. If their fix is to get new switches this problem will not go away.
no, switches get used to directly switch large currents all the time, and work just fine when specced correctly. your vacuum cleaner probably has a direct power switch, most AC-powered power tools do as well, your PC's PSU probably has one. light switches are a thing too, and they seem to hold up pretty fine over time. they really can just choose a better switch and itt'll be fine. (or do some investigating to see if that's even necessary or if that unit was just defective)
@@spambot7110 Look at the pictures of the fault. That switch is a tiny hobby grade toggle. It is clearly out of spec for this printer with its heating function and thus needed a mosfet, but the manufacturer claims it malfunctioned. Either they wont admit they messed up or took a shortcut for this prototype or they are making a legitimate mistake and will either ignore it as a fluke or put the same spec switch's from a different supplier into new units.
@ThePrintHouse it is.. as a regular printer user, I really wanted someone to talk about the safety concerns of these fully enclosed printers... I had faced a similar issue during an 18-hour print.. and it got me thinking that safety did not even cross my mind until that point. 3d printers are regularly heated, and if you live in a place that is less humid, something will burn at some point .... I think your video will make people think about safety (not with one brand but enclosed 3d printer as a whole)
I think your use of the word "Explosion" is entirely incorrect and disingenuous. The switch melted, that's far from an explosion, about as far as stubbing your toe and claiming your leg was ripped off.
The switch did more than melt, however fair play. That being said, regardless of the term I used and whatever actually happened. I had to inspect the printer to make sure there wasn't additional damage. This absolutely should have never happened and while ultraprint was communicating regularly, they should have immediately, without questions, shipped a new printer so I could test a working version. I should never be asked to open the back cover and begin cutting wires and soldering. I understand that it's a prototype and not many units exist, but I'm very confident there were more printers manufactured that could have been shipped out. If there was literally no more printers built then the run around they gave me makes sense, but just be honest about it.
I think most concerning would be trusting someones review of printers when they use the word explosion to describe a burnt out switch. A bit of clickbait is to be expected but I find your continued use of explosion infuriating.
lol how dramatic. crazy that someone that reviews FDM printers doesn't know any of the technical terms or procedures to fix a fried switch instantly with zero help.
I do not think it is dramatic to be making this video. The goal for me was to be as transparent as humanly possible. I made this exact video so ultraprint backers and customers can decide for themselves if this is a nonissue or a major issue. The video was made to be transparent so you can have the freedom to make your own judgment on the situation. To me, this sounds like it is not an issue to you, which is great to hear! :) Im sure there are other viewers and potential backers/customers that this will be a major issue for. I could have opened the printer myself and easily debugged and fixed the problem if I had a spare switch to swap in. As I mentioned at the beginning of the video, this was an unscripted one take video, it was also filmed at midnight, so I didnt have the mental capacity to use all of your preferred buzz words. Given this was a very preproduction machine I didnt want to touch anything without consulting the company first. If I did and caused undo harm to the printer the company could blame me for the issue and not want to work with me further. Given that, I needed to talk with them first in order to open the printer to begin work and before the printer was opened I had no idea what the exact magnitude of the damage was. Additionally, in a situation like this, I could very easily understand if the company desires for me to ship the printer back to the factory for them to debug the issue and run their own in house failure review without me interacting with the machine more. I very much respect your viewership and your comment interaction, but there are quite a lot of behind the scenes things, like what I mentioned above, that might not be considered from a viewer like yourself. I hope you can understand the situation a little more clearly now.
you could've just said the machine broke, or failed, or if you wanted to be spicy you could say it "popped". but if you put "explosion" in the title, meaning 90% of the people watched the video not because they're interested in what you're actually talking about, but because they thought they were gonna either hear a really wild story or learn about some new hazard they were unaware of. i thought maybe the switch thing was setup, and you were building up to some harrowing situation where the failed switch ignited a resin vapor cloud, or some other... "explosioney" thing. but no, what actually happened was highly specific and relatively minor QC issue. you wasted a few minutes of my time, and for this crime you deserve... idk maybe 4 or 5 pissed off comments.
I am sorry for wasting you time, honestly. Though I will say in this particular case I stand by what Ive written in the title and thumbnail because I want people to watch this video. Those that backed the product need to find this video so they can determine if this is an issue major enough to cancel their backing or their order. The verbiage I chose in the video is a separate debate and I dont think it is worth refilming the video over, though I can understand certain people's complaints about the words I chose.

awesome to see you guys come out and address things head on. I can tell customer safety is at the top of your concerns.

this is a scam

Hey no worries man!! Also Ross is a great guy!!! This printer uses a single light source :)

i think i misunderstood your comment to be saying that using switches in general was a bad design, not that specific switch
They are running 200W of heater and a UV lamp with an external power supply? How fat is said power supply?
I was provided a 180W external power supply.
Thanks for sharing this
Of course! I hope it was helpful!!

Up to you, big hoss
"one take wonder" literally has a jump cut every 2 seconds or less. :P
It was one take. It was jump cut to shorten it down from 30 mins to 22 mins.
Very misleading title...
