Aluminum HBP Arms For The Replicator! by bottleworks Dec 27, 2012

Description

Upgrade your arms!
Have you been having issues with your MakerBot Replicator HBP arms warp and sag? The Replicator is a Revolutionary 3D printer pushing the limits of small scale 3D printing. As people reach new advances in desktop 3D printing, stability and consistency are critical. The original HBP arms are made of ABS plastic. Unfortunately, when the plastic arms are exposed to the heat generated by the HBP, they warp, sag, and otherwise move. This warping and sagging make it incredibly difficult to have a consistently level HBP. As a result, constant tweaks and adjustments are required. Another issue with the arms is the low mass. During high speed printing, the original, low mass arms, lightly vibrate. These vibrations contribute to further distort the object being printed.
Virtually eliminate these issues by upgrading to custom CNC milled aluminum HBP arms. These replacement arms are made out of a single solid piece of 6061 aluminum.
* The arms are designed to replace the original plastic arms with no other modifications.
* Additional mass. Fully assembled weight of 931.5 grams. The added mass reduces harmonics and vibration.
* No more constant adjustments due to unwanted arm movement.
* The upper bearing retainers help block loose items from falling behind the platform and getting lost.
You can find out more Information on the aluminum arms @ bctechnologicalsolutions.com/replicatorarms
Notice some grinding marks? Good catch! The arms photographed are a prototype set. Those grinding marks were from last minute modifications due to clearance issues. ALL production arms will have NO grinding marks - only clean, milled surfaces.

I placed my order on April 16 and I have not received my items yet. I have messaged you through your website and through thingiverse and have received no response. What is the status of my order. I have an update as of May 20th that a shipping label was printed but the label shows it has not been scanned or picked up. Sorry for posting on here but I would like a little clarification on what the status of my order is. Please give me a call 832-224-8844 or email me at [email protected]

If you need a design file for the arms, use the design files provided by MBI in Thing 18813 (http://www.thingiverse.com/thi.... There you will find all the design files for the Replicator 1. And the arms are the same for the Rep 1, Rep 2, and Rep 2X. You can start with those files and then mod them however you want.

Instructions

I printed these out at 120mm/sec (Thanks to Sailfish!).
ABS Plastic
15% Infill/Octagon Pattern.
.27mm layer height.
I printed with full support, but with NO raft.
I've added a revised STL for all arms shipped 3/18/13 and later that are being installed in a Replicator 1. The older arms used different lower bearing retainers.

Hey Bottleworks, do you have anymore of those aluminum arms for the replicator 1 available for sale? Thanks.

bottleworks on Nov 6, 2013 said:

Some aluminum bar stock was just dropped off an hour ago.... I should have some available again very shortly.

bottleworks on Aug 3, 2013 said:

I now have some in stock and available for shipment.

jimconstable on May 7, 2013 said:

I can't order on your site currently. Paypal says it is an error in your site?

bottleworks on May 7, 2013 said:

This style arm for the replicator 1 is no longer available. I will be adapting the new style arms designed for the replicator 2/2X to fit the replicator 1. I'll make a post when that is available.

TCorgard on Apr 7, 2013 said:

I noticed on mine, the holes for the side screws on the main platform did not line up right. I was able to get them to seat in the end. The holes were off by about a 1/32" I think. I also noticed some resistance with the up down movement. A few items I have printed so far now have what seems to be "Z-Wobble". I am going to print the 20mm cal cube and see what it looks like.

bottleworks on Apr 7, 2013 said:

I've been told that the platform wood dimensions changed slightly during Replicator 1 production which has caused the holes to be slightly off. If you have resistance in the bearings, it's typically caused by damage when removing the bearings. They are easily damaged. Z wobble can only be caused by a couple things. Make sure the wood is ---absolutely--- seated in the slots. Loosen the bottom and top Z rod adjustments. Jog the z axis up and down (via control panel), then re-tighten the rod adjustments. If this doesn't solve you z wobble, you may have slightly bent Z rods.

Just a public service reminder

***PRINT YOUR PARTS BEFORE YOU TAKE YOUR PRINTER APART***

Not that I did that or anything. Really, I didn't. (But I almost did ;) )

RobertDunn on Apr 1, 2013 said:

I installed my arms on the printers but am running into an issue with resistance on the linear bearing shafts. it seems that after installing the bearings that they are slightly off and solutions on how to resolve this as the plastform no longer slides fluid up and down on the shafts. there is some resistance even with the bearing and shafts being properly greased.

bottleworks on Apr 1, 2013 said:

Send me an email and I can help you resolve this. These comment forums don't work well for trouble shooting.

acilia on Apr 1, 2013 said:

Any plans on making these arms for the Rep2?

MaikaiGuy on Mar 31, 2013 said:

OMG!!! This has been, by far, the best upgrade I've made to my printer!!! I installed them on Friday and have been printing all weekend. I keep checking the build level and it's perfect. I haven't had to touch it. Also the prints are better.

Sometimes the printer prints a part of a section, then comes back to finish that section. I could always tell where that happened in the finished print. Not anymore. That was an unexpected benefit.

I can't thank you enough for making these things. Wow! This is a "must have" upgrade. Makerbot should put aluminum arms on all their new printers. This is an unbelievable improvement.

I'm sorry for being so verbose here, but this is the kind of stability improvement that takes 3D printing one giant step closer to having one of these in every home. I can't see how one could make a reliable/repeatable printer without these.

bottleworks on Apr 1, 2013 said:

That's great to hear. I'm glad you like them. If you have time, be sure to post a photo of your upgraded bot under the "made" section of this page. Thanks!

fredini on Mar 24, 2013 said:

What does it entail to install these? How far do you have to rip the bot apart to get them on there?

bottleworks on Mar 24, 2013 said:

I would plan for 1 to 2 hours to upgrade the machine. The arms come with step by step instructions for the replicator 1...In full color. It's not hard to do.

bottleworks on Mar 24, 2013 said:

I've added a revised STL for all arms shipped 3/18/13 and later that are being installed in a Replicator 1.

Deamos on Mar 23, 2013 said:

Got mine in today! Thanks Bottleworks! Great build quality and not really too difficult to rebuild. All in all, it took me about 2 and a half hours from start to finish, taking a few breaks in between. The worst part was having to sand down the rear wood on the platform to fit the arms, but the instructions mentioned there would be a good chance I would have to.

bottleworks on Mar 23, 2013 said:

Interesting that you had to sand the the back wood part... Which shipment were you in? I'm trying to figure out if there is a discrepancy that I missed. The newest revision shouldn't need any sanding.

RobertDunn on Mar 21, 2013 said:

Have my arms shipped yet you said they would ship on the 15 and now its the 20th.

bottleworks on Mar 21, 2013 said:

I'm sorry, there was never a ship date of the 15th. A group of 24 shipped this week. There'll be the final group shipped next week. If you did not receive a shipping notification from PayPal, you are likely in the second group. The arms are shipped in the order in which they were purchased.

oldmaker on Mar 13, 2013 said:

Your HBP aluminum looks very thick. What is the thickness? Thanks

bottleworks on Mar 13, 2013 said:

They are less wide at .75". The height is aprox the same as the OEM arms.

ckchavez on Mar 12, 2013 said:

I've been using my new Arms over the last few days and they really are a worthy upgrade.Thanks bottleworks! So far, I've noticed that the Build plate leveling is staying consistent and print plate vibration seems really minimized. Thanks for making this happen.

delsydsoftware on Mar 11, 2013 said:

I finally got around to installing my aluminum arms today. It took a bit longer than I expected, but the results were instantly noticeable when I started leveling the glass HBP. It really is rock solid, and I was able to get the HBP leveled much more quickly. I have the printer knocking out a guardian squirrel at 8 microns at 120mms (Yay for Sailfish!) and the exterior quality of the print looks a lot more consistent and less noisy than before.

bottleworks on Mar 11, 2013 said:

Up late I see... That's great to hear! Over time, you will forget how to re-level (because you never need to!).

GeraldO on Mar 6, 2013 said:

Just got mine in the mail today! Sending them off to anodizing ASAP and will mount shortly after :)

bottleworks on Mar 6, 2013 said:

I should warn you that the Bearing area may have to be sanded after you anodize them. These were MachineD to fit the bearings there isn't much extra clearance for the anodizing layer

bottleworks on Mar 6, 2013 said:

It will be interesting to see how thick the Anodizing layers are.

bottleworks on Mar 5, 2013 said:

I just got the server. It has crashed. Hardware failure....

bottleworks on Mar 5, 2013 said:

Temp server running. My poor ANS 700/200 has died!

RobertDunn on Mar 5, 2013 said:

Your site is real slow you might want to think about switching over to zencart for easier purchasing and order tracking. Please shoot me an email over to [email protected] so i can order some aluminum arms. I have 6 replicators that i want to upgrade so that would be great.

bottleworks on Mar 5, 2013 said:

I just sent you an email.

bottleworks on Mar 5, 2013 said:

Speed is not the issue. There is a power outage. The web site will be back up in 3 hours. From there you can order, however, I suspect the system I have setup though PayPal will charge you equal shipping on each set you buy (no discount). It's a bit crazy to charge $90 domestic/ $180 international. I'll contact you directly about your order interest.

Deamos on Feb 27, 2013 said:

Ordered a Set up yesterday! Looking forward to not having to deal with the platform warping or vibration as much!

Kronos10 on Feb 26, 2013 said:

Mine came in and they work great! Thank you for doing this!

ThePuzzleGeek on Feb 25, 2013 said:

One set of shiny, sturdy arms now fitted . Thank you Bottleworks for making this happen! Just running a quick test print now and it's all looking good - they'll get a proper work out tomorrow.

Printed_Solid on Feb 21, 2013 said:

I placed an order for a pair from the third batch. Are people that have received and installed these finding that this takes care of leveling issues?

bottleworks on Feb 21, 2013 said:

Only 25 have been shipped so far. Half of those went overseas (so still in transit). The next 25 are shipping Monday. So, more will have their hands on these soon. Those that do have them installed - please post a photo in the "made" section!!

andyways on Feb 18, 2013 said:

thank you bottleworks!

bottleworks on Feb 16, 2013 said:

I've just opened up the ordering for the third batch of arms. I've already ordered the metal, so that should cut down on the lead time.

BitBuilder on Feb 16, 2013 said:

Got my order in!

bottleworks on Feb 13, 2013 said:

Ok. By now the US buyers of the first batch of arms should have received them. Let me know what you think. Feedback is welcome. Post a picture of your bot in the "made" section of this page.

MakerCoast on Feb 14, 2013 said:

Everything worked out great. Had to sand the wood down a bit for everything to fit snug. I'll post a picture later today of it completed. Thank you once again!

bottleworks on Feb 8, 2013 said:

I'm packing up the first set of 25 arms right now...

MakerCoast on Feb 8, 2013 said:

Can't wait! :-)

Printed_Solid on Feb 3, 2013 said:

AH, all sold out. I'd like to buy a kit if you run some more.

bottleworks on Feb 3, 2013 said:

Stay Tuned. More May come.

diecast_dirtboy on Jan 29, 2013 said:

Any chance they will fit the Replicator 2? I would like to upgrade and improve the Replicator 2. Maybe add an aluminum build plate to eliminate warping.

bottleworks on Jan 29, 2013 said:

They -might-. I don't have a Rep2 available, so I can't say for sure. I know a couple people who are getting some of the first sets have both Replicator 1 & 2s. Maybe they will check it out.

BitBuilder on Jan 23, 2013 said:

Just found this, I'm hoping you do another run of these...

bottleworks on Jan 23, 2013 said:

It might happen. The first sets haven't shipped yet, so we will see. The first sets should be shipping soon.

Anonymous on Jan 12, 2013 said:

Money sent. Is there a replacement guide so I know what I'll be getting into?

bottleworks on Jan 12, 2013 said:

Yes. I will be putting up a guide. There are some steps that people may skip that I feel are needed if I just say "good luck".

bottleworks on Jan 11, 2013 said:

The freight company called... They will be dropping off the alumium stock on Monday.

bottleworks on Jan 11, 2013 said:

Now only 7 sets...

bottleworks on Jan 10, 2013 said:

Now only 8 sets left.

bottleworks on Jan 9, 2013 said:

Only 9 sets are left for sale...

bottleworks on Jan 6, 2013 said:

I bring news! Good, bad, and just news...
The good news is that this is still happening and I don't have to refund everyone their money. Also, there will be 50 total sets made. There are currently 32 sets sold. It took longer to order the material then I hoped. I should have it by then end of this week (Jan 10-11th). I ordered 296.3 Lbs of aluminum...56 linear feet. The holidays pushed back everything. I couldn't get in contact with people and it was to the point that I was going to throw in the towel. Then some costs jumped up at the last minute. That's why there are 50 sets being made. It was going to cost more per set with only making 32.
So the bad news: It's going to take a little longer then I thought. The first 25 sets will be available 3 weeks after the material arrives. That brings the shipping date for the first 25 set to 4 weeks from now. The second 25 sets will be done 5-7 weeks from now (depending on you're order date). If you ordered before Dec 28th, 2012 @ 2 PM, you're within the first set of 25. After 2 PM, you're in the second round. I hope this timeline is worse case and things will move faster.

So, with that said, I've got 18 more sets for sale.

you're awesome man so great idea ! :)

TeamTeamUSA on Dec 28, 2012 said:

Nice idea!

Would MakerBeams work for this too? One of these should yield several arm pairs: https://www.sparkfun.com/produ...

Your welcome to design your own. This project is for a "drop in" replacement. Not a rework.

Thank you for doing this! Payment sent!

drandolph on Dec 27, 2012 said:

When my set comes in I'll redo my platform files to make it not have the recesses and fill in the slots I'm seeing on the supports. Not a big deal and I'm sure it won't make a bit of difference but it will make for a nice look. I also plan to re-cut my platform out of aluminum.
